Building Regulations
Design Information
New Zealand Building Code (NZBC)
General
3.1
In the opinion of BRANZ, Thermakraft BULLDOG
2° Window Sealing Tape, if designed, used, installed and
maintained in accordance with the statements and conditions
of this Appraisal, will meet or contribute to meeting the
following provisions of the NZBC:
Clause B2 DURABILITY: Performance B2.3.1(b), 15 years and
B2.3.2. Thermakraft BULLDOG 2° Window Sealing Tape meets
these requirements. See Paragraphs 8.1 and 8.2.
Clause E2 EXTERNAL MOISTURE: Performance E2.3.2.
Thermakraft BULLDOG 2° Window Sealing Tape contributes to
meeting this requirement. See Paragraphs 7.1 – 7.4 and 11.1.
Clause F2 HAZARDOUS BUILDING MATERIALS: Performance
F2.3.1. Thermakraft BULLDOG 2° Window Sealing Tape meets
this requirement and will not present a health hazard to people.
7.1
Thermakraft BULLDOG 2° Window Sealing Tape meets
the requirements of AC148: 2001 which is an alternative
solution to the version of AC148 referenced by NZBC Acceptable
Solution E2/AS1 Paragraph 9.1.5(b). The installation method
for Thermakraft BULLDOG 2° Window Sealing Tape is an
alternative solution to the installation method shown within
NZBC Acceptable Solution E2/AS1, Figures 72A and 72B.
7.2
The use of flexible flashing systems around window
and door joinery openings is critical to assist the overall
weathertightness performance of window and door joinery
installations.
7.3
Thermakraft BULLDOG 2° Window Sealing Tape is
suitable for use over flexible wall underlays compatible with the
flashing tape in NZS 3604 Wind Zones up to and including
Extra High. In the Extra High Wind Zone, the flexible underlay
must be installed over a rigid underlay complying with NZBC
Acceptable Solution E2/AS1, Table 23.
7.4
Thermakraft BULLDOG 2° Window Sealing Tape is
designed to prevent air leakage and water penetration around
window and door openings at framing junctions (e.g. at the
sill trimmer and opening stud junction), and to keep any water
that gets past the cladding, or through the joinery, from direct
contact with the framing timber. 7.5
Thermakraft BULLDOG 2° Window Sealing Tape is not
designed to overcome poor detailing and workmanship of the
window or door joinery installation. The system must not be
considered in isolation, but be considered as part of the wall
cladding system. Thermakraft BULLDOG 2° Window Sealing
Tape is designed to be used in conjunction with air seals and
joinery flashing systems, not as a substitute.
7.6
When Thermakraft BULLDOG 2° Window Sealing
Tape is used in conjunction with LOSP (light organic solvent
preservative) treated timber, the solvent from the timber
treatment must be allowed to evaporate (generally at least one
week) prior to the installation of the system.
3.2
This is an Appraisal of an Alternative Solution in terms
of New Zealand Building Code compliance. See Paragraph 7.1.
Technical Specification
4.1 System components and accessories supplied by
Thermakraft Industries (NZ) Ltd are:
• Thermakraft BULLDOG 2° Window Sealing Tape is a
polymeric faced, bituminous modified, self adhesive tape
with a release backing paper. The tape is supplied in rolls
200, 150 and 75 mm wide x 25 m long. The rolls are
wrapped in clear polythene film.
• The Thermakraft Corner Moulded Piece is made from inert
polyethylene and is coloured orange. It is used in conjunction
with the Thermakraft BULLDOG 2° Window Sealing Tape
and building underlays as part of the Thermakraft BULLDOG
2° Window Sealing Tape system.
• The Thermakraft Tool is used to ensure proper adhesion of
the Thermakraft BULLDOG 2° Window Sealing Tape and to
achieve a tight fit into corners.
4.2
Accessories used with the system which are supplied
by the installer are:
• Thermakraft Corner Moulded Piece fixings – staples, clouts
or other temporary fixings to attach the corner mould to the
framing prior to the installation of the Thermakraft BULLDOG
2° Window Sealing Tape.
Durability
8.1
Assessment of durability to meet the NZBC is based
on difficulty of access and replacement, and the ability to detect
failure of Thermakraft BULLDOG 2° Window Sealing Tape both
during normal use and maintenance of the building.
Serviceable Life
8.2
Provided it is not exposed to the weather or ultraviolet light for a total of more than 42 days, and provided the
exterior cladding is maintained in accordance with the cladding
manufacturer’s instructions and the cladding remains weather
resistant, Thermakraft BULLDOG 2° Window Sealing Tape is
expected to have a serviceable life equal to that of the cladding.
Handling and Storage
5.1
Handling and storage of all materials supplied by
Thermakraft Industries (NZ) Ltd, whether on or off site, is under
the control of the installer. Thermakraft BULLDOG 2° Window
Sealing Tape and accessories must be protected from damage
and weather. Rolls must be stored under cover, in clean, dry
conditions away from direct exposure to sunlight.
Maintenance
9.1
No maintenance is required for Thermakraft BULLDOG
2° Window Sealing Tape. Regular checks, at least annually,
must be made of the junctions between the joinery and wall
cladding to ensure that they are maintained weathertight and
that the primary means of weather resistance for the junction
e.g. flashing, sealant, etc continues to perform its function, to
ensure that water will not penetrate the cladding.
Technical Literature
6.1
Refer to the Appraisals listing on the BRANZ website
for details of the current Technical Literature for Thermakraft
BULLDOG 2° Window Sealing Tape. The Technical Literature
must be read in conjunction with this Appraisal. All aspects

Prevention of Fire Occurring
Installation Temperature
13.8 Thermakraft BULLDOG 2° Window Sealing Tape must
not be installed at temperatures of less than 2°C. When installed
at temperatures less than 5°C, the tape must be mechanically
fixed in place with staples or clouts. When the temperature has
reached 5°C, the Thermakraft Tool must again be used to ensure
adequate adhesion of the tape is achieved.
Inspections
13.9 The Technical Literature must be referred to during the
inspection of Thermakraft BULLDOG 2° Window Sealing Tape

Solutions C/AS1 to C/AS6, Paragraph 7.5.9 for the protection of
combustible materials.
External Moisture
11.1 Where a cladding manufacturer specifies the use of
generic flashing tapes around window and door joinery openings
at framing junctions as part of their system, or they specify the
use of flexible flashing tapes that comply with NZBC E2/AS1,
Paragraph 9.1.5(b), Thermakraft BULLDOG 2° Window Sealing
Tape may be used.
Basis of Appraisal
The following is a summary of the technical investigations
carried out:
Installation Information
Tests
Installation Skill Level Requirements
14.1 Testing of Thermakraft BULLDOG 2° Window Sealing
Tape has been completed by BRANZ to the requirements of ICC
Evaluation Service Acceptance Criteria for Flashing Materials
AC148:2001. The adhesion of Thermakraft BULLDOG 2°
Window Sealing Tape to black bituminous Kraft building paper
complying with the requirements of NZBC Acceptable Solution
E2/AS1, Table 23 and selected other synthetic wall underlays
has been tested and found to be satisfactory.
12.1 Installation of Thermakraft BULLDOG 2° Window
Sealing Tape must be completed by tradespersons with an
understanding of flexible flashing tape systems, in accordance
with instructions given within Thermakraft BULLDOG 2°
Window Sealing Tape Technical Literature and this Appraisal.
General
13.1 The selected wall underlay must be installed in
accordance with the manufacturer’s instructions, and must
completely cover the joinery opening. The underlay is then cut
on a 45° angle away from each corner of the opening so the
flaps can be folded into the opening and secured to the interior
face of the timber framing.
13.2 Fit a Thermakraft Corner Moulded Piece into each of
the bottom corners to create a seal at the corner junction. The
corner piece must be fixed to the framing with staples or clouts.
13.3 Before the Thermakraft BULLDOG 2° Window Sealing
Tape is applied, the substrate surfaces must be clean, dry and
free from any surface contaminants such as dust and grease
that may cause loss of adhesion.
13.4 A length of Thermakraft BULLDOG 2° Window Sealing
Tape must be cut to the length of the sill plus 400 mm. The
tape is installed flush with the interior face of the opening and is
applied along the entire length of the sill and 200 mm up each
jamb. The overhanging tape is cut at the corner of the opening
to allow the tape to be folded onto the face of the building
underlay. The Thermakraft Tool must be used to ensure that
adequate adhesion of the tape is achieved and that the tape is
installed tight into the sill/jamb junction.
13.5 A 400 mm length of Thermakraft BULLDOG 2°
Window Sealing Tape must be installed 200 mm down the jamb
and 200 mm along the lintel at each of the top corners of the
window or door joinery opening. A 75 mm wide x 100 mm long
sealing tape ‘butterfly’ must be installed at 45° across the corner
of the head/jamb junction overlapping the corner by 3 mm to
create a seal at the corner junction.
13.6 Thermakraft BULLDOG 2° Window Sealing Tape must
not be stretched. To avoid wastage, the tape can be lapped
100 mm minimum onto itself without reducing the performance
of the Thermakraft BULLDOG 2° Window Sealing Tape System.
13.7 If the Thermakraft BULLDOG 2° Window Sealing Tape
is exposed to the weather or UV light for more than 42 days,
then it must be replaced with new material.

Natural Lighting Systems Performance
2.4.1.1.2 DURABILITY
(a) Sheet Characteristics
The useful life of Natural Lighting products is determined by their ongoing ability to allow sufficient light into
the building. Table 2.4A gives a guide for the recommended use of each of the product types and the expected
useful life based on light transmission.
The long-term performance of Durolite products is enhanced by the use of a 100-micron integral gel coat surface
rather than a laminated polyester film (Maxilite®).

2.4.1.1.3 LIGHT TRANSMISSION DESIGN
The Durolite® range and Maxilite® provide a source of soft, shade free natural light to building interiors. This results
from the refraction by the glass fibre reinforcement in the sheet material, in contrast to the more direct and intense
light and heat transmission of clear glass or clear plastic. The light transmitted excludes 99% of UVB radiation, thus
minimising burning. Photosynthetically active radiation is transmitted through Durolite and Maxilite allowing plant
growth in greenhouse buildings.
Durolite and Maxilite are available in a range of tints to reduce the level of light transmission if required.
Refer Table 2.4D for Relative Light Transmission.
Opal and Woolstore tints may not be available ex stock, but can be manufactured in minimum run quantities.
Discuss with your Dimond representative well in advance of your required delivery date to ensure the product required
to meet your light transmission needs will be available.
Design Method For Light Transmission
To calculate the level of light transmission through Natural Lighting installed in a building the following procedure can
be used.

2.4.1.1.4 SOLAR HEAT GAIN
There are four ways of reducing solar heat gain using the Dimond Natural Lighting range.
1. Durolite and Maxilite are available in a range of clear and colour tints in Dimond profiles to reduce the level of
solar heat gain as required. Refer to Table 2.4I for relative solar heat gain.
2. Use Durolite HeatGuard 4 in any of the Dimond profiles to reduce the total amount of heat generated by solar
transmission by 13% without any noticeable loss of visible light transmission when compared to Durolite clear.
Choose Durolite HG4 to reduce 20% heat while allowing 64% of visible light through the sheet.
3. Use Durolite HeatGuard 8 in any of the Dimond profiles to further reduce the total amount of heat created by
solar transmission. When compared to tinted Durolite opal sheet, Durolite HG8 reduces heat by 20% while still
allowing 49% of visible light through the sheet.
4. Using the DSR 5 system, a double skin of translucent sheet forms a 20mm air space to reduce both the amount
of heat transfer into the building and heat loss out of the building. Also a reduction in condensation forming on
the system’s underside is expected. Only available for use with SS900 or Topspan steel profiled roofing. Refer detail
2.4.1.1.10, Fig 11.
For the System in point 1 above, the heat gain resulting from the use of Durolite or Maxilite® can be estimated in a
simple way using the following calculations: (This does not take into account heat transmissions through other materials
making up the building envelope.)

2.4.1.1.5 LOAD SPAN DESIGN
Table 2.4K provides the maximum spans for each product type Glasslite, Maxilite, Durolite, in all the grades such as
clear, HG and FG for each profile and sheet thickness limited by the ultimate limit state capacities given. The load
span data is based on the number of fasteners/sheet/purlin given. The load capacities apply to both inward and outward
uniformly distributed loads. Table 2.4K does not cover Natural Lighting Systems intended to support concentrated
loads (e.g. foot traffic). Consult Dimond for alternative systems if design consideration is to be given to concentrated
load support.
Fastener Design
Dimond Natural Lighting sheets must be fixed with screw fasteners of the same type and length for the matching metal
sheeting. The fastener frequency should be specified according to Table 2.4K.
Weatherlok roofing washers may be used to achieve a seal and to spread wind uplift reaction loads. For roofs with design
wind loads close to the maximum values below or above 2.0 kPa, use the matching metal profiled washer and 36Ø
EPDM seal. Side lap stitching and pre-drilled oversize holes may be required (refer Section 2.4.1.3.2).

Natural Lighting Systems Safety
2.4.1.1.5 Continued
Mid Span Support
Whenever the span capability of the Dimond Natural Lighting product does not match the purlin spacing used for the
adjoining metal sheets, a mid span support must be used. The sheets must be fastened to the mid span support in the
same manner as they are fastened to the purlins. Mid span supports are required to reduce sheet flutter due to wind
loads and are not intended to support concentrated loads.
1⁄2
Sheet Widths Spans
The use of profiled 1⁄2 sheet widths, lapping over the side of the steel sheets, allow the spans of the selected profile
Natural Lighting sheet to be increased by up to 40%, while still achieving the same ultimate limit state capacity, before
needing mid supports. Half width sheets must have side lap stitching as shown in Table 2.4M, Section 2.4.1.3.2.
2.4.1.1.6 CONDENSATION CONTROL & INSULATION
Condensation can occur on the underside of Natural Lighting sheet when the building is not sufficiently ventilated or
moisture is generated within the building space.
The following three methods are recommended options to help reduce the effect of condensation that may form on
Natural Lighting.
1. Install a system that incorporates Dimond Skylight film as a translucent underlay. Refer 2.4.1.1.10 Detailed
Drawings Fig. 1. This is a low performance system which in the extreme cases of low exterior temperatures,
condensation may still form on the underside of the skylight film. Otherwise the skylight film is intended to carry
condensation moisture dripping from the underside of the Natural Lighting sheet to the outside of the building,
similar to building paper.
2. Install a system that incorporates a double skin of Natural Lighting sheeting with an air gap between. In colder
climates the air gap provides additional insulation and reduces the likelihood of condensation forming on the
underside of the inner surface.
For additional design considerations relating to condensation control by ventilation, refer to Section 2.4.4.
2.4.1.1.7 FIRE RESISTANCE
The fire resistance properties of the Natural Lighting products have been evaluated by recognised Fire Safety
Consultants, resulting in the opinion that Durolite can be used within the New Zealand Building Code requirements
for fire safety given the following guidelines.
Durolite FireGuard 2 (FG2) and Durolite FireGuard 3 (FG3) are manufactured with fire retardant polyester resin and
have been tested by BRANZ.
Durolite FG2 achieves a Group 2 Number classification to the NZBC verification method C/VM2 appendix A.
Durolite FG3 achieves a Group 3 Number classification to the NZBC verification method C/VM2 appendix A.
BRANZ Test Report FH 5552-TT for FG2 and BRANZ Test Report FH 5553-TT for FG3 are available upon request.
Contact Dimond on 0800 ROOFSPEC (0800 766 377).
Durolite FG2 and FG3 are available in all profiles and standard colour tint options, e.g. HG4.

The Dimond Natural Lighting sheets with safety mesh laid under are not intended to carry foot traffic and Dimond
recommend using Dimond Webglass if trafficable sheets are required.
When accidental fall safety is an issue, usage outside the scope of this table (e.g. different profiles, thinner sheet or
greater spans) may require the installation of an approved safety mesh – see Section 2.4.5.
Alternatively Dimond Webglass may be used, which is manufactured to a thicker sheet weight of 2.1 mm and reinforced
with a heavy woven glass mat which provides continuous reinforcement both across and up the profiled sheet. This
reinforcement gives the sheet enough strength under an impact load such that safety mesh is not required under the
webglass sheet.

Natural Lighting Systems Components
2.4.1.2.2 BARRIER STRIP
The recommended strip to use as a barrier between the purlin/mesh and Natural Lighting sheets is Purlin Protection
Strip (PPS). These flat sheet strips of GPP are provided with double sided tape on one side for attachment onto the
purlin over the netting or safety mesh before the Natural Lighting sheets are fixed down. They are supplied in either
70mm or 90mm wide strips to best suit the purlin flange width.
2.4.1.2.3 FASTENERS
1. Primary Natural Lighting sheet fasteners should be the correct length gauge and grade of screw fastener for the
profile and will therefore be specified as the same fastener as for the adjoining metal sheeting. Clearfix 12g x 65mm
long hex head self-drilling screws, drill both an oversized clearance hole in the Natural Lighting sheet and self drill
into timber or steel purlins. Suitable for Corrugate, Styleline/VeedekTM, Dimondclad into timber or steel purlins
and DP955, BB900, LT7 and V-Rib profiles into steel purlins only.
2. Washers, metal profiled shaped washers used with a 36Ø EPDM seal.
3. Lap stitching fasteners

Natural Lighting Systems Installation
2.4.1.3 INSTALLATION INFORMATION
2.4.1.3.1 HANDLING AND STORAGE
Dimond Natural Lighting sheets are delivered to the site in bundles which should remain strapped together and stored
where damage will not occur. Ensure the product remains clean and dry. Edges of bundles must be protected during
cranage. Sheets must be lifted into place, not dragged.
Maxilite® sheets have a thin plastic film laminated to each surface. As these films are critical to the products’ long
term performance, it is highly important that damage to sheet surfaces is avoided during handling, installation and
subsequent use. Durolite has a 100 micron integral gel coat top surface which is less likely to suffer damage during
handling that will affect long term performance. The underside however does have a thin plastic film laminate and care
must be taken to avoid damaging it.
2.4.1.3.2 SHEET LAYOUT AND FASTENERS
(a) Supporting Structure
Before installation is commenced, the supporting structure must be free of sharp protrusions, or abrasive surfaces
that may come into contact with the sheets. Ensure the purlin spacing is not greater than the span limitations for the
selected profile as detailed in Section 2.4.1.5. A pliable, non-abrasive separation layer must be placed between the sheet
underside and the wire netting/purlin surface. Refer to Section 2.4.1.2.2.
(b) Mid Span Support
In instances where single Dimond Natural Lighting sheets are to be used as skylights and placed between adjacent
metal sheets, they may be installed on purlin spacings that exceeds the maximum span limitation for the sheet thickness
chosen provided a mid span support member is incorporated to enable extra fastening to reduce sheet flutter in high
winds. See Fig 12 for typically installed view. Where two or more Dimond Natural Lighting sheets are laid side by side
purlin spacings must be reduced to suit the maximum span of the Natural Lighting material. (For decking profile refer
to paragraph (e) below.)
(c) Layout
Sidelaps are designed for both edges of the Natural Lighting sheets to overlap the adjoining metal sheets. All sidelaps
must lap over the profile rib of the sheet. It is preferred that the sheets are run from ridges to eaves without end laps.
Where end laps are necessary, they should be a minimum of 200mm and fully sealed at both edges of the lap with a
neutral cure silicone sealant. Laps must be positioned on a purlin in such a manner that the overlapping sheet edge is
firmly fastened against the underlapping sheet.
(d) Fastening
Dimond Natural Lighting sheets will undergo movement at the fastener position. To correctly allow for this, the
sheets should be pre-drilled through the crest of the rib or corrugation with a hole diameter at least 2mm greater than
the screw. Larger pre-drilled holes will be required if the sheet length is greater than 6m and allowance for thermal
expansion is required – see Section 2.1.3.4.
Ensure the correct fixings and washers are used in accordance with Section 2.4.1.1.5.
Screw fasteners must be tightened sufficiently to prevent the sheet lifting from the framing but not overtight so as to
cause rib deformation. To control sheet flutter in high winds side lap stitching through the rib top is required similar to
the primary fasteners and should be completed at spacings that achieve the side lap fastening required in Table 2.4M.
Use profiled washers with 36Ø EPDM seals into 8mmØ oversized holes in the natural lighting sheets.

2.4.1.3 Continued
(e) DD400 Decking Profile
Where one sheet of Natural Lighting DD400 or decking profile is used in conjunction with the metal decking, the
sheets are laid using the under/over method. The sheets are held in position by galvanised bolts, which are located
through each rib. The bolts must also pass through the rib of the metal decking and the deck clip to ensure correct
hold down is achieved. If purlin spacings are greater than 1200mm centres or in high wind areas additional bolts must
be placed through the sheet edge laps at 600mm centres. Where two or more Natural Lighting sheets are laid side by
side, deck clips are replaced by Dimond Tee Rails manufactured from .55mm G550 Z450 Galvanised Steel or AZ150
Zincalume. These are located at every side lap. Fixings are placed through ribs and Tee Rails at 600mm centres ensuring
that a fastener is immediately adjacent to the purlin. The Tee Rail must be fixed to the purlin through both flanges.
(f )Dimondek 630 Profile
Where one sheet of Natural Lighting is fixed between metal Dimondek 630, the sheets are laid over using the following
method. The centre support rib of the fixing clip is required to be removed. If the spans of the Natural Lighting are
greater than 900mm, span breakers are required, up to a maximum of 900mm centre modules. Span breakers can only
be installed one way around with the larger rib on the span breaker clipping and snapping up into the underside of
the overlap rib of the metal Dimondek 630 when installed from above. The span breakers are then positioned in their
correct positions and the sheets are placed over, before a 10mm clearance hole is drilled though the Natural Lighting.
The position of the hole is in the horizontal area adjacent to the side lap at both the purlin and mid span supports, using
the side lap clips as a template. On top of each metal rib, either side of the Natural Lighting a continuous side lap 6mm
thick x 15mm wide EPDM foam seal is adhered to run the full length of the Natural Lighting sheet. Then the sheet is
held in position by fixing a 12g x 65mm tek screw through the side lap clip and Natural Lighting sheet into the span
breaker. This allows the Natural Lighting sheet to expand and contract without being connected to the metal roofing
sheet.
A centre fixing using a 14g x 95mm long tek through a 10mm clearance hole and a Dimondek 630 profiled washer with
36 diameter EPDM seal is required on the purlin line only.
On the ends of Natural Lighting sheet 70x50x25mm thick foam blocks are pushed up between the metal and the
Natural Lighting sheet to fill in the gap created. Refer Fig. 10 in Section 2.4.1.1.10.
With end lapped sheet that will form runs over 25m, we recommend overlapping 200mm, applying 4 beads of neutral
curing silicone sealant approx. 10mm ø in size. Allow these to tack off for 20 mins before screwing down. This will
allow the beads of silicone to roll and not shear under thermal expansion, and continue to provide a seal.
Refer 2.4.1.1.10, Fig. 10 for treatment of sheet ends.
2.4.1.3.3 FLASHINGS AND STOP ENDS
In addition to normal requirements (refer Sections 2.2.4 and 2.3.3) stop ends must be provided on all roof pitches, at
the top end of all Natural Lighting sheet installations to provide a watertight seal under all over flashings, including
immediately below any roof penetration. Sheet stop ends can be achieved by using either:
a. Compressible Closed-Cell Foam Strip to match the profiles. Use if roof pitch is greater than 15 degrees.
b. Metal angle folded to the height of the profile rib and fastened to the end of the sheet with rivets. Neutral curing
sealant is then applied to the intersection of the sheet and metal angle. Refer Section 2.4.1.1.10, Fig. 5.
2.4.1.3.4 GENERAL WORKMANSHIP
In addition to normal requirements (refer Section 2.3.4) note the following:
1. Sheeting Cutting
Natural Lighting sheets can be supplied cut to custom lengths. Where onsite cutting is necessary a fine tooth
handsaw or an electric saw fitted with a fibre disc must be used. Breathing protection must be worn to prevent
inhalation of glass fibres and resin dust. To resist cracking, the sheets must be firmly supported during cutting
operations.
2. Water Run-Off
Dimond Natural Lighting sheets, as with any other plastic or prepainted metal roofing materials, act as inert
catchment areas for rainwater, and run-off from these areas onto unpainted galvanised surfaces may cause accelerated
corrosion of the galvanised steel.

accordance with the requirements of the NZBC and the roof
cladding manufacturer.
General
7.2 Thermakraft Covertek 407 Fire Retardant SelfSupporting Roof Underlay is intended for use as an alternative
to conventional kraft paper roof underlays, which are fixed over
timber or steel framed roofs in order to limit the entry of wind
into the roof cavity, and to assist in the moisture management of
the roof cladding system.
7.3
The material also provides a degree of temporary
weather protection during early construction. However, the
product will not make the roof weathertight and some wetting
of the underlying structure is always possible before the roof
cladding is installed. Hence, the entire building must be closedin and made weatherproof before moisture sensitive materials
such as ceiling linings and insulation materials are installed.

Notes
1. In any category, spans above the maximum shown should not be used. Category 1 and 2 maximum spans are based on static point load testing as a guide,
and further limited by practical experience of roof performance under dynamic foot traffic loads. Category 3 maximum spans are limited as a guide to
achieving satisfactory appearance for wall cladding.
2. Loads given are based on 5 screw fasteners/sheet/purlin.
3. Loads given are limited to a maximum of 4.5 kPa. If design requirements exceed this limit, contact Dimond for specific advice.
4. Duraclad
– Serviceability Limit State loads are not applicable to the Duraclad material, as it does not experience permanent deformation.
– System must include Safety Mesh if intended for use as a Restricted-Access roof. Refer Section 2.2.1.8.
5. N/R = not recommended.
6. End span capacities given in this table are based on the end span being 2/3 of the internal span.
7. Design Criteria for Limit State Capacities
a) Serviceability Limit State
No deflection or permanent distortion that would cause unacceptable appearance, side lap leakage or water ponding, due to foot traffic point load, inward
or outward wind loads or snow loads.
b) Ultimate Limit State
No pull through of fixings or fastener withdrawal resulting in sheet detachment due to wind up-lift (outward) loads.
System Design
The span capacity of Corrugate is determined from the Corrugate Limit State Load / Span Capacity Chart using the sections of the Chart appropriate to
the grade and type of material, and to the category of serviceability selected from the three categories below.
It is recommended that to obtain a dependable design strength capacity for the ultimate limit state, a reduction factor of = 0.8 is applied.
The capacities given do not apply for cyclonic wind conditions.
Serviceability Requirements
While these categories are given for design guidance to meet the serviceability limit state criteria, foot traffic point load damage may still occur if there is
careless placement of these point loads.
Service Category
Description
1. Unrestricted-access roof Expect regular foot traffic to access the roof for maintenance work and able to walk anywhere on the roof. No congregation
of foot traffic expected.
2. Restricted-access roof
Expect occasional foot traffic educated to walk only on the purlin lines, in the profile pans, or carefully across two profile ribs.
Walkways installed where regular traffic is expected, and “Restricted Access” signs placed at access points.
3. Non-access roof or wall Walls or roofs where no foot traffic access is possible or permitted. If necessary, “No Roof Access” signs used.

Fastener Design
Corrugate should be screw fixed to either timber or steel purlins. The use of the appropriate length of 12g
screw, or when fixing aluminium the use of a 12g or 14g Alutite, on both a non cavity and cavity system will ensure
failure by screw pull out will not occur under loads within the scope of the Limit State Load / Span Capacity Chart.

* If sarking or insulation is used over the purlins or for wall cladding fixing onto a cavity batten, into the stud,
the screw length will need to be increased.
For screw size range and fastener / washer assembly refer Section 2.2.3.1.
The Limit State Load / Span Capacity Chart is based on 5 screw fasteners/sheet/purlin without the use of load
spreading washers (except for Duraclad material, which must be fitted with either profiled metal washers and
36mm EPDM seals, or 32mm Weatherlok washers).
Profiled metal washers are recommended for use:
1. On end spans, or large internal spans where the Ultimate Limit State distributed load is limiting. Contact
Dimond for specific advice in these design cases.
2. When required to enable the fixing system to accommodate the thermal movement of long sheets – see
Section 2.1.3.4 Thermal Movement.
3. Wherever the designer wishes to ensure the risk of fastener over-tightening will not cause dishing of the
crest of the profile rib.
Use in serviceability categories (1) or (2) can allow the reduction of fasteners to 3 screw fasteners/sheet/purlin.
If this is done, the distributed load capacities given in the chart should be reduced using a multiplying factor of 0.6.
Long spans may require the specification and use of side lap stitching screws – see Section 2.3.2C Installation
Information: Layout and Fastening.

COVERTEK
™
403/405/40
Covertek is a fire retardant, absorbent and
breathable synthetic roof and wall underlay.
Constructed using a microporous water
resistant film sandwiched between two
layers of shrink resistant spun-bonded
polyolefin. Designed as a means of managing
condensation, water vapour transfer and
water ingress in roofs and wall applications.
In Roof Applications
Intended for use as a alternative to conventional kraft paper
CONTROL OF
CONDENSATION
In climatic regions where condensation risks are high, such
as cold or high humidity areas, care needs to be taken in
specifying the correct design and installation to prevent
moisture build-up in the roof cavities. Factors which adversely
affect the condensation risk in roofing systems include:
• Humid, and/or cold climatic regions
roof underlay, fixed over timber or steel framed roofs and to
• Warm/Skillion roof construction
assist in the moisture management of roof cladding systems.
• Low roof cavity air volume and restricted air movement
In Wall Applications
• Omitting Vapour Control Layers
Intended for use as an alternative to conventional kraft paper
wall underlays, fixed over timber or steel frame walls in order
to limit the entry of wind and water into building cavities.
Covertek has a Flammability Index ≤5 and therefore meets
the requirements of NZBC Acceptable Solutions C/AS2 to
• Ceiling penetrations and entry of warm air into roof
cavities
• Occupancy activities which have high moisture loading on
conditioned spaces
C/AS6 Paragraph (4.17.86), for the surface finish requirements
• Low pitched roof
of suspended flexible fabric used as an underlay to exterior
• Bulk insulation
cladding that is exposed to view in occupied spaces. It may
therfore be used with no restrictions in all building.
For horizontal laying, see NZBC E2/AS1. For vertical laying,
refer MRM Roofing Code of Practice.
Note: If applying window sealing tape to Covertek, improved
adhesion performance can be achieved by using a hot air gun
(gentle on the window sealing tape) or the use of a spray
primer/adhesive.
• Building structures ability to naturally dry Construction
Moisture
Skillion and Warm Roof Construction are particularly sensitive
to moisture accumulation and the design and installation
of roof construction needs to take into account the higher
condensation risks. Refer MRM Code of Practice for details.

Window Flashing Tape
is used to seal the up
stand of the window
head flashing to the
building underlay.
(Refer to the cladding
manufacturer’s details).
IMPORTANT INFORMATION
To assist the adhesion of window flashing tapes
Thermakraft suggests the following two options this is
particularly relevant in the following conditions:
• In temperatures below 5ºC
• When adhering to non-woven surfaces such as Covertek™
• When the tape has been lifted or moved after initial application
Application of Heat:
• Press the window sill tape into position in the usual manner
• Apply a gentle heat, using a heat gun on low heat to the top of the window sill tape
• Once the adhesive starts to soften use the Thermakraft tool or a roller to firmly press the tape into the wall underlay ensuring good adhesion
• Take care not to damage the foil face lining
Application of Spray Adhesive:
• Before installing the window sill flashing tape apply a light coating of suitable solvent based spray adhesive (not water based)
• Allow spray adhesive to flash dry. When dry to the touch apply the window sill flashing in the normal manner
• Take care once applied not to disturb the tape until fully cured
Adhesives and Solvents:
After the installation of Aluband/Bulldog, ensure that the
edges do not come into contact with solvent based sealants or
adhesives. Solvents in these products can adversely affect the
adhesion or dissolve the bituminous adhesive and cause it to
run. If the application of solvent based adhesives or sealants are
necessary, cover the edges with Thermakraft F150 pure foil tape
or equivalent foil tape to form a barrier.
LOSP Treated Timber:
Aluband/Bulldog should not be applied directly on to the timber,
or indirectly on to a timber sheathed in underlay that has been
freshly LOSP treated. Always allow the solvent to fully flash off
prior to wrapping in underlay and applying Aluband/Bulldog.
Surface Preparation:
Always ensure that Aluband/Bulldog is applied to surfaces that
are clean and free of dust, contaminates, solvents, oils or waxes.
Exposure Time:
Aluband/Bulldog must not be left exposed to the elements for
more than 42 days.

INTRODUCTION
In the interest of your safety, building regulatory Authorities in Australia and New Zealand require
any woodfire installation to comply with Installation Standard AS/NZS 2918:2001. They may also
have local requirements in addition to those in the Standard. Check with your local Building Authority before commencing installation to find if you will require a Building Consent and whether there are extra requirements. This woodfire has been tested to ensure that it will meet the appropriate safety Standard requirements when these instructions are followed. As the safety and
emission performance can be affected by altering the appliance, no modifications are allowed
without written permission from the manufacturer.
The model I9000 has been tested to demonstrate compliance with current general emission requirements in New Zealand, but some areas have stricter limits. So check before purchasing or
installing, the requirements for your area.

INSTALLATION REQUIREMENTS
INSTALLATIONS- FLOOR TO CEILING ENCLOSURE:
1.
Inspect the house construction at the proposed installation position to verify that the flue casing (250mm diameter, plus 25mm clearance all around) can pass through the ceiling space
without requiring the removal of essential roof or ceiling support beams. The flue centerline will
be 305mm from the rear wall and it must be at least 610mm from any side wall. (See Fig. 2).
Fig. 2
FLOOR PLAN
2.
Drop a plumb line from the ceiling to the floor to verify the centerline and cut a hole at least
300mm square or round through the ceiling on this centerline. If preferred, there may be no
ceiling inside the fireplace enclosure. (See step 21).
3.
Ensure that there are suitable noggins at either the ceiling or roof level (or both) to provide anchorage for the outer flue casing bracing angles.
4.
Frame up the enclosure using normal 90x45mm dressed timber, verifying that it will be on the
flue centerline. (See Fig. 2). The overall depth should be (610 - t) mm, where ‘t’ is the cladding
thickness. The distance between the front uprights must be 755mm (use the supplied metal
support angle as a spacer). Fix the metal support angle between the two front uprights at a
height of 700mm above the base of the shielding (zero clearance) box.
5.
For an ‘elevated’ installation (See Fig. 6), fix two extra noggins (90x45x955) across the front
opening of the enclosure, one at the bottom and the other at the desired ‘elevation’ height.
These extra nogs will carry the front cladding below the heater. Fix two 90x45 bearers running
from front to back behind the top extra noggins, positioned 210mm each side of the enclosure
centerline to provide support for the shielding box rails. The bearer tops must be flush with the
top of the top extra nog. Provide a suitable support at the rear ends of the bearers to carry the
weight of the appliance. The shielding box can sit directly on the bearers. No insulation is necessary. The usual three noggins may be fixed at each side of the enclosure. At the front, the
lowest wooden nog must have its lower face at least 1470mm above the top of the bearers for
an elevated installation. Further wooden nogs can be fitted above this one.
6.
Side cladding: This can be made from GIB board or other wall cladding materials. Remember
to fit two air vents, see fig. 4,5,6,7. You must leave the cladding off at least one side until the
flue system has been installed.
7.
Fix the cladding to the front of the enclosure, including down each side of the opening. All
front cladding from the floor up must be of heat resistant material such as PROMATECT H,
ETERPAN LD or SUPALUX. The heat resistant cladding shall cover the whole width of the
enclosure up to 510mm from the centre of the appliance. The heat resistant cladding must
have a minimum height as follows: For installations with a mantel shelf it must go up to the
height of the mantle shelf (see fig. 4&5 for min. height of mantle shelf). For installations without
a mantle shelf it must go up 1470mm above the base of the shielding (zero clearance) box.
5
8.
Wall surfaces directly above the heater may reach 85 degrees C, so materials such as
wallpaper and water based paint may be adversely affected. For durability of finishes
and surfaces you should contact the relevant manufacturers for their specifications.
Glen Dimplex accepts no responsibility for the deterioration of surfaces of finishes. It is
usually convenient to carry the same material right up to the ceiling level. At the lower edge,
drill (4.5mm diameter) holes into the metal support angle through the holes in the top flange of
the shielding box and fasten with the self threading screws provided.
9.
Mantel Pillars: You are allowed to have combustible mantel pillars. They mast be placed at
least 460mm from the centre of the appliance and must not protrude more than 100mm from
the wall where the fascia is butting against.
10.
For heat sensitive floors, construct an insulating floor protector of the shape shown in the
Floor Plan (Fig.2) and projection sizes on page 11, (see below for concrete floors). The insulating floor protector is constructed of one layer of 6mm thick PROMATECT H or SUPALUX,
topped with a layer of tiles or slate. The floor protector must be at least 875mm wide. It is desirable to carry the floor protector all the way inside the enclosure to ensure that the bottom of
the shielding box does not rest below the top surface of the floor protector.
11.
Note: For elevated installations (bottom of the shielding box rails at least 300mm above floor
level), the floor protector (min. size: 300mm from cladding x 875mm wide) may be installed
after the appliance is in position as it does not extend into the enclosure. However, its rear
edge must butt up against the face of the heat-proof front cladding below the appliance, and
the joint at that point must be sealed to prevent the possibility of ember penetration. In this
case an ash floor protector is sufficient. Construction requirements for an ash floor protector
are: one sheet of 6mm fibre cement board (e.g. Hardies TILE & SLATE UNDERLAY) covered
with ceramic tiles or slate.
12.
Cement tiles or slate to the top of the floor protector. The part inside the enclosure will not be
visible and therefore does not need complete coverage. It is necessary to fix the finishing layer
only under the support rails in this area. The visible edges of the floor protector are best finished with wooden trim or tiles after the stove has been installed.
13.
Penetrate the roofing material on the flue centerline. Working from the bottom, assemble sections of the flue pipe and the inner and outer casings and pass them up through the hole in
the roof. Remember the flue pipe sections must be fixed together at each joint with at least
three monel or stainless steel fasteners, and the crimped ends of the flue casings go to the
top. The joints of the flue pipes must be sealed with an appropriate fire proof sealant. When
the flue system is in its final position, the top of the outer casings must be above the ridge line
or roof as follows: If the flue centerline is within 3m from the ridge, the outer casing must end
at least 600mm above the ridge. If it is further than 3m from the ridge, the outer casing must
extend at least 1000mm above the point of roof penetration. In some cases where there are
trees or high buildings in the vicinity, it may be necessary to increase the height to avoid downdraughts. You need to temporary support the flue system so that you can install the appliance.
14.
Assemble the base, sides, back, top shield assembly and top panel of the shielding box. The
top shield rests on the top edges of the inner heat shields of the cabinet. Make sure the back
flange hooks over the shield on the rear panel (See Fig. 3).
15.
Attach the two standoff brackets to the sides of the shielding box panels (if not already fitted).
Use four pop rivets for each bracket.
16.
Slide the assembly into place in the enclosure. After centralizing, fix the flange of the top
panel of the shielding box through the cladding into the metal angle support. Use 2/ 12g x
25mm screws.
17.
The special adapter spigot ring with holes to ventilate the space between the flue and the
inner casing as well as the space between the inner casing and the outer casing has to be attached with 4 screws 8g x 13mm to the top of the shielding box. Both flue casings (inner & outer) will engage with this special adapter spigot ring.
18.
In New Zealand and some parts of Australia, Standards require that the appliance be seismic
restraint to prevent shifting in the event of an earthquake. To provide seismic restraint, fix
the shielding box to the floor (bearers in an elevated installation) with two 6mm masonry
anchors (DYNABOLTS) or two 12 gauge screws . Use the two holes in the bottom of the
shielding box spaced 687mm apart.
6
19.
Now go to the firebox cabinet and remove the two retaining screws and slide out the top section of the firebox cabinet.
20.
Attach the two centralizing brackets to the side panels of the firebox cabinet, flanges facing
outwards. Use two screws provided for each bracket.
21.
Slide the firebox cabinet into the shielding box. Centralize it and secure the restraint brackets
to the shielding box flanges.
22.
Complete the seismic restraint of the fire by screwing the base plate of the fire to the bottom
of the shielding box with two M6 screws. Use the two holes in the base spaced 464mm apart.
23.
Lower the assembled flue pipe (sections must be sealed and held together with three S/S fasteners) and seal and fix it to the flue socket of the appliance. Use stainless steel screws.
Lower the inner casing and engage it with the special adaptor spigot ring, repeat this step with
the outer casing. See Fig. 8 & 9 for flue pipe and casing lengths.
24.
Fit the two casing bracing angles at either ceiling or roof level as appropriate. Fix a suitable
flashing where the outer casing penetrates the roof.
25.
IMPORTANT: TO AVOID THE RISK OF A FIRE, COVER THE ENTIRE OPEN SPACE SURROUNDING THE OUTER CASING AT CEILING LEVEL WITH WIRE NETTING WHICH HAS
A MESH SMALL ENOUGH TO PREVENT THE ENTRY OF BIRDS OR VERMIN INTO THE
ENCLOSURE.
26.
At the top of the flue pipe, fix the flashing cone and fit the cowl in the usual way. There must be
a 25mm gap between the top of the two casings and the flashing cone, so that the spaces between the flue pipe, inner and outer casings are properly vented.
27.
Re-fit the removable top section of the firebox cabinet and secure it with two screws.
28.
Fix the cladding to the enclosure side(s).
29.
Fit the fascia. See instructions supplied with the fascia.
30.
Ensure that the ceiling baffle, secondary air tube and the two side bricks and the two rear
bricks are in the correct position.
31.
Check and ensure that the fan rests on four rubber grommets and that the front two grommets
are resting over the two upturned lugs of the cabinet base plate. (Australian models only).
32.
Finish the floor protector by installing an edge trim if desired.

NOTES FOR VARIATIONS
CONCRETE FLOORS
The above instructions assume that the appliance is being installed on a heat sensitive floor such as
timber or particle board. Where the floor is not heat sensitive (e.g. concrete), the insulating floor protector may be omitted. However, if heat sensitive floor coverings (e.g.carpet) are fitted it will be necessary to keep them at a safe distance. The most practical way to do this is to fix tiles to the floor
where the floor protector normally would be. This will make the top of the floor protector approximately flush with the floor covering, so a larger floor protector will be needed. It must extend the min. of
440mm from the face of the front cladding, but the 875mm width will be sufficient (see Fig. 5). Remember to raise the shielding box by the same amount as the thickness of the tiles on the concrete
floor.
BRICK FACED INTERNAL ENCLOSURES
The flue system installation and clearance requirements are as detailed above. Brick wall construction will normally require a cast concrete base slab, so this slab could be extended to provide the
necessary floor protection.
CAUTION. If your local Building Requirements permit laying the concrete slab on top of a wooden
floor, it should be made of lightweight concrete and even then foundation support may be required. In
any case, the slab should be poured on top of one layer of 16mm thick Micore 160 board (covered
with plastic sheet to keep it dry) to prevent heat damage to the wooden floor.
The top surface can be finished with bricks or tiles etc. In all cases the floor protector dimensions
must be as previously shown.
EXTERNAL INSTALLATIONS
In the case where the enclosure is to be erected outside the house, the shielding and flue system
installation details will still apply. It is important to remember that the aperture in the wall of the house
will need to be sufficient high to permit the installation of heat resistant paneling around the appliance
to at least 1470mm above the bottom of the shielding box rails. Suitable foundations will be required
to support the weight of the enclosure and the appliance and weatherproofing of the entire assembly
will be necessary.
HEARTH REQUIREMENTS:
You need an insulating floor protector (hearth). The minimum requirement for an insulating floor
protector (hearth) is one layer of 6mm thick ‘PROMATECT H’, SUPALUX, or ETERPAN LD (or similar with a heat transition coefficient of 5 W/m³ K), and a layer of tiles or slate. This will give a thickness of approximately 14mm, and the extension from the face of the glass must be at least 441mm
(or 440mm from fireplace surround) if the floor protector is flush with the surrounding heat sensitive
material. The floor protector must be at least 875mm wide. It is desirable to carry the floor protector all the way inside the fireplace to ensure that the bottom of the zero clearance box does
not rest below the top surface of the floor protector.
The projection distance for the floor protector can be reduced if the height of the hearth is more than
0mm above combustible materials. Please refer to the following table:

INSTALLING THE FASCIA
Preparing the appliance:
Remove the door: Open door and lift door until the top pivot disengages and then lower the door to
free the bottom of the hinge.
Preparing the fascia:
Unpack the fascia and fit the Zero Clearance Infill Panel to the bottom panel of the fascia. Use 4
screws provided. The Zero Clearance Infill Panel is supplied with the Zero Clearance Enclosure, not

Note: This statement shall only be relied upon by the Building Consent Authority named above. Liability under this statement accrues to the
Design Firm only. The total maximum amount of damages payable arising from this statement and all other statements provided to the
Building Consent Authority in relation to this building work, whether in contract, tort or otherwise (including negligence) is limited to the
sum of $200,000*.
This form is to accompany Form 2 of the Building (Forms) Regulations 2004 for the application of a Building Consent.
GUIDANCE ON USE OF PRODUCER STATEMENTS
Producer statements were first introduced with the Building Act 1992. The producer statements were developed by a
combined task committee consisting of members of the New Zealand Institute of Architects, Institution of Professional
Engineers New Zealand, Association of Consulting Engineers New Zealand in consultation with the Building Officials
Institute of New Zealand. The original suite of producer statements has been revised at the date of this form as a
result of enactment of the Building Act (2004) by these organisations to ensure standard use within the industry.
The producer statement system is intended to provide Building Consent Authorities (BCAs) with reasonable grounds for
the issue of a Building Consent or a Code Compliance Certificate, without having to duplicate design or construction
checking undertaken by others.
PS1 Design
PS2 Design Review
Intended for use by a suitably qualified independent design professional in circumstances where the
BCA accepts a producer statement for establishing reasonable
grounds to issue a Building Consent;
Intended for use by a suitably qualified independent design professional where the BCA accepts an
independent design professional’s review as the basis for establishing
PS3 Construction
reasonable grounds to issue a Building Consent;
Forms commonly used as a certificate of completion of building work are Schedule 6 of NZS 3910:20031
or Schedules E1/E2 of NZIA’s SCC 2007 2
PS4 Construction
Review
Intended for use by a suitably qualified independent design professional who undertakes construction
monitoring of the building works where the BCA requests a producer
statement prior to issuing a Code Compliance Certificate.
This must be accompanied by a statement of completion of building work (Schedule 6).
The following guidelines are provided by ACENZ, IPENZ and
NZIA to interpret the Producer Statement. Competence of
Design Professional This statement is made by a Design Firm
that has undertaken a contract of services for the services
named, and is signed by a person authorised by that firm to
verify the processes within the firm and competence of
its designers.
A competent design professional will have a professional
qualification and proven current competence through
registration on a national competence based register,
either as a Chartered Professional Engineer (CPEng) or a
Registered Architect.
Membership of a professional body, such as the Institution of
Professional Engineers New Zealand (IPENZ)or the
New Zealand Institute of Architects (NZIA), provides additional
assurance of the designer’s standing within the profession. If the
design firm is a member of the Association of Consulting
Engineers New Zealand
(ACENZ), this provides additional assurance about the
standing of the firm.
Persons or firms meeting these criteria satisfy the
term “suitably qualified independent design professional”.
* Professional Indemnity Insurance As part of membership
requirements, ACENZ requires all
member firms to hold Professional Indemnity Insurance to a
minimum level. The PI insurance minimum stated on the front of
this form reflect standard, small projects. If the parties deem this
inappropriate for large projects the minimum may be up to
$500,000.
Professional Services during Construction Phase There are
several levels of service which a Design Firm may provide
during the construction phase of a project (CM1CM5) 3 (OL1OL4) 2 . The Building Consent Authority is encouraged to
require that the service to be provided by the Design Firm is
appropriate for the project concerned. Requirement to
provide Producer Statement PS4 Building Consent
Authorities should ensure that the
applicant is aware of any requirement for producer statements
for the construction phase of building work at
the time the building consent is issued as no design
professional should be expected to provide a producer
statement unless such a requirement forms part of the
Design Firm’s engagement. Attached Particulars
Attached particulars referred to in this producer statement refer to
supplementary information appended to the producer statement.

PosiGlaze
Glass Balustrade System
The Solution
for Cantilevered
Structural Glass
Balustrades
Innovative design
The PosiGlaze Glass Balustrade
System was developed for
cantilevered structural balustrades
to cope with the transition from
monolithic Toughened Safety Glass
(TSG) to Toughened Laminated
Safety Glass (TLSG).
The unique design uses a special
high strength hollow core aluminium
extrusion and special glass clamp kits
that clamp the glass and locate into the
section. This means the system can be
used on 12, 15, & 19mm TSG and 13.5,
17.5 and 21.5 LTSG without holes in
the glass. Holes can make the systems
more complex and often the holes are
the point of failure.
The other key to PosiGlaze is its clever
locating and adjusting technique which
allows the installers to adjust the glass
panels once in place, with a turn of a
spanner, saving on installation time.

System types
Design & testing
Compliance
The PosiGlaze Glass Balustrade
System can be base fixed or
side fixed for top or side (face)
mounted balustrade applications.
The PosiGlaze Glass Balustrade
System has been designed and
tested to New Zealand and British
Standards, which use similar
occupancy types and loading
requirements.
The PosiGlaze Glass Balustrade
System can be used for
compliance with NZ Building Code
Clause F4 – Safety from falling,
with barrier heights to suit the
design application, normally 1000
or 1100mm.
The 120mm high x 72mm wide extrusion
comes in 3 metre lengths all predrilled
ready for fixing and once the section
is fitted the glass is easily dropped in
and located. The systems also makes
re-glazing easy, or the glass type or
thickness can be easily changed at a
later date.
A top seal strip section and gasket
are installed after the glass has been
adjusted to give a clean top edge look
and matching end caps complete
the system.
For the side fixed systems an additional
clip on side cladding and tapered base
cladding section is used for aesthetics
and to cover the fixing holes.

PosiGlaze PG180S Side Fix System
180mm high x 74mm wide
Finish
The sections and covers are fully
anodized for durability and come
standard in a unique brushed
anodized finish which give a
“Stainless Steel Effect”.
The UK testing to BS 6180:2011, involved
base and side fixed systems to concrete
and steel and a range of glass types and
thicknesses from 15 to 21mm including
TLSG with EVA and SG interlayer.
The NZ testing is to AS/NZS 1170 loadings
in accordance with B1/VM1 Amend 8, for
Occupancy A,B,E,C3 and the higher C1,C2
and D loadings.
Therefore the systems can be used for all
residential applications and commercial
applications, except for C5 (over-crowding).
Installation
The Posiglaze Glass Balustrade
System is glazed with Metro
GlassTech, TempaFloat,
TempaSoak, TempaScreen or
TempaPrint Toughened Safety
Glass (TSG) or SafeLite Toughened
Laminated Safety Glass (TLSG),
using either, PVB, CIP, EVA or SG
interlayer. Note that the breakage
characteristic can alter with
different interlayer’s.
The maximum glass height is a function
of the glass type, thickness, occupancy
loading, and wind loading and a design
table or specific design is available from
Metro GlassTech.
Test data and independent engineered
and certified Producer Statements (PS1)
are available from Metro GlassTech for
compliance with the NZ Building Code.
After installation by Metro GlassTech
a code compliant PS3 is provided.
The PosiGlaze Glass Balustrade System
can be used with or without interlinking
handrail or top rails and comply with the
recommendation of the DBH Guidance on
Barrier Design section 4.1.4.3.
TempaSoak - Heat Soaked TSG is
recommended for barriers with interlinking
handrails or top rails
SafeLite TLSG is recommended for barrier
without interlinking handrails
or top rails.
(Refer Metro GlassTech SafeLite brochure).

SUPALUX® - Introduction
SUPALUX® consist of a calcium silicate matrix of reinforced fibres and
fillers, 100% asbestos free The SUPALUX® formula is cured to form a
dimensionally stable board through an autoclave process where the
board is subject to pressurised steam and high temperature. The result
is a board that is lightweight, has a high impact resistance, high fire
resistance, and with all the excellent qualities that SUPALUX® has been
delivering to a loyal following of customers and end users for more
than 25 years.
EFFECT OF MOISTURE
Saturate a SUPALUX® board in water and allow it to dry and it will return to
its original condition with almost no degradation. Moisture and dampness
has no permanent effect on the mechanical or fire performance of the
material. It is therefore possible to install SUPALUX® at any time in the
building programme.
IMPACT RESISTANT
A SUPALUX® wall construction has fulfilled all the severe duty requirements
for impact, crowd pressure, deflection and multiple cycles of door slam in
accordance with British Standard 5234, proving its excellent impact
resistance.
THERMAL
SUPALUX® has very low thermal conductivity of 0.24 W/mK.
BIOLOGICAL
SUPALUX® does not attract insects or vermin and does not support mould
growth.
CHEMICAL
SUPALUX® is not affected by brine or dilute chlorine and other chemical
solutions. It is also resistant to low concentrations of most acids, alkalis,
bleaching agents and solvents.
COMPATIBILITY
SUPALUX® is compatible with most building materials, is non-caustic and
will neither promote corrosion nor affect bituminous compounds.
The surface of SUPALUX® can readily receive many forms of architectural
treatments from painting, wallpapering, waterproofing membranes, tiling, and
other common aesthetic finishes. It is advised that the decorating materials
manufacturers instructions should be strictly adhered to at all times.

SUPALUX® - Terminology of Fire Resistance.
FIRE RESISTANCE OF STRUCTURES
Fire resistance is not a property of a material but the performance of a
complete element of structure which will generally be comprised of a number
of different materials and components. The fire resistance of loadbearing
and non loadbearing partitions and celilings are determined by a test in
accordance with the criteria of British Standard 476: Part 21 and 22: 1987
respectively.
Specifications shown in this document have been tested or assessed
by independent authorities for compliance with International Standards.
Additional testing has been carried out worldwide.
A fire resisting construction can be any one of a number of elements
in a building, for example a wall, ceiling, duct, protected shaft or cavity
barrier. This document gives details of some of the constructions used
in fire resisting applications. for full details on many other fire
resistant constructions please refer to Intumex Asia Pacific.
NON COMBUSTIBLE MATERIALS
Building materials are classified as non combustible when they are tested to
and pass BS 476: Part 4: 1970. SUPALUX® is non combustible. Under the
Singapore building code, BS 476: Part 11: 1982 can be used to determine
the heat emission of materials and thus the combustibility of a product.
These tests provide a measure of the propensity of materials to generate
heat and flames under standardised heat exposure conditions, and
represent some of the highest and most stringent standard for the reaction
to fire performance of materials.
FIRE TEST
Fire resistance is determined in tests which subject a representative
specimen to heating conditions based on a standard temperature/time
curve (below) while subject to its design loading where appropriate. Test
methods are detailed in the various parts of the BS 476 series of standards.
The fire resistance of a specimen is the time in minutes for which it continues
to meet the criteria of Stability, Integrity and Insulation where appropriate.
The specimen under test is progressively heated in an accurately controlled
furnace, the temperature of which varies with time and follows as closely as
possible the International Standard curve. This is set out in graph form and
is called the time/temperature curve. The heat evolved is not necessarily
that which is produced in a true fire situation but is an agreed standard for
purposes of comparison for elements of construction.
After 30 minutes the temperature of the furnace is 841°C, increasing to
945°C after 60 minutes. Then to 1049°C after 120 minutes to a maximum
1213°C after 360 minutes. These figures illustrate how severe the
performance tests are in respect of elements of structure.
The fire resistance of an element is the time in minutes from the start of the
test until failure occurs under any one of the criteria of Stability, Integrity
and Insulation if all are appropriate to the particular type of element being
tested; or, if no failure occurs, until the test is terminated.
For example, a test result showing
Stability: 120
Integrity:120
Insulation: 15
would mean that a specimen failed in respect of the Insulation ctiteria after
15 minutes, but complied with the other criteria for at least 120 minutes.
A large number of various types of elements of structure using SUPALUX®
have been tested over a many years.
The designer of a building can therefore refer quite readily to previous test
results from a range of official publications and will know whether or not the
particular type of construction selected will be appropriate in respect of the
fire resistance of the proposed elements of structure.
Should the designer wish to use new or untested materials, testing would
be necessary and a satisfactory report would need to be furnished prior
to approval being given for the use of such elements in the construction
of a particular building.
Stability
The ability of a system, e.g. ventilation and smoke extraction
ductwork, to remain in place and capable of fulfilling its intended
function throughout the duration of exposure to fire. this also applies
to load-bearting elements of construction and refers to the ability of
the specimen to stay in place and support the required load for the
duration of its exposure to fire.
Integrity
The ability of a separating element of construction to contain a fire
within one compatment and to remain free from holes, cracks or
fissures through which fire, smoke or hot gases could pass to any
ajacent compartment. This also refers to the ability of the specimen to
prevent any sustained flaming on the unexposed face.
Insulation
The ability of a separating element to restrict the temperature rise on
the exposed face to specified levels, i.e. a maximum permitted 140°
rise as an average over the whole specimen and/or a 180° rise at ony
single point on the unexposed face of the construction.

Biolytix BioPod (BF6) Wastewater Treatment System
Specifications
The Biolytix BioPod (BF6) is an onsite treatment system designed to treat wastewater from domestic
sources. It uses a single tank configuration based on an enhanced trickling filter process which
mimics a natural soil habitat. The BF6 is certified to comply with AS/NZS 1546.3:2008 and must be
operated in accordance with this standard.
Effluent Quality
The BF6 wastewater treatment system generates secondary treated effluent of the following quality:
•
•
5-day Biochemical Oxygen Demand (BOD5) <20 mg/L
Suspended solids <30 mg/L
The effluent must be disposed of as stipulated by the responsible authorities. AS/NZS 1547:2000
describes discharge options for secondary-treated effluent. However, the Regional Authority
regulations applying to a specific site may be different and more stringent. The local Regional
Authority should be consulted before making a decision.
Maximum Loading
•
•
•
Flow rate: 1600 L per day
Organic loading as BOD5: 700 g per day
Suspended solids loading: 700 g per day
Important: The actual maximum loading of an installed BF6 is limited by the capacity of the dispersal
system it discharges to. For example, if the BF6 is connected to a land dispersal system with a
capacity of 800 L/day, then the BF6 must not be loaded at more than 800 L/day.
Operation
•
•
•
•
•
•
Emergency storage capacity: 1450 L
Temperature and humidity: Operates under normal temperature and humidity conditions
experienced in Australia and New Zealand. If required, systems installed in cold and hot
climates use insulation.
Noise < 40 dB LAeq at a distance of 1 m
Electricity consumption (per year): Treatment process 44 kWh; effluent pump typically 165
kWh (per year). Effluent pump power use can vary significantly depending on the size and
location of the dispersal system and the actual household water usage.
Maintenance: Requires one maintenance service per year (Note: Some Regional Authorities
require at least two services per year regardless of the type of on-site wastewater system)
Minimum serviceable life: 15 years

Treatment Process
The BF6 filter bed (Figure 1) is contained in an Everhard injection moulded high grade polypropylene
tank and consists of six alternating layers of drainage matrix elements and humus matrix elements.
Both layers contain plastic trickling filter media contained in open-mesh bags. In the filter bed there is
in excess of 2m3 of plastic filter media with a high porosity and a high specific surface area. The
humus layers additionally contain coco peat, the fibrous structure of which significantly increases the
available treatment surface. The three drainage/humus double-layers are separated by a 3mm coarse
HDPE mesh fabric.
The resulting filter bed mimics a natural soil habitat, containing a diverse ecosystem of micro and
macro-organisms. These organisms aerobically treat the wastewater as it percolates through the bed,
prevent the accumulation of sludge, and keep the filter aerated. On commissioning, the filter is
inoculated with 1 kg of tiger worms (Eisenia Fetida). These worms propagate and burrow through the
filter bed, thereby keeping its structure open and porous. A Schego M2K3 air pump is used to provide
additional air to the bed at the rate of 350 L per hour.
A geotextile filter layer with a nominal pore size of 80 micron separates the filter bed from the effluent
storage sump. Its purpose is to remove fine solids from the treated effluent. To support the bed, the
sump is filled to a depth of 300 mm with a matrix of plastic media. It drains into the central pump well,
from where the effluent is pumped using a submersible pump to a land dispersal system (e.g.
subsurface drip irrigation). The pump is controlled by a factory set float switch. The total bed depth
including sump is 1050 mm.

Configuration Options
Installation
The BF6 can be installed in-ground or above ground. Local Council restrictions may apply to aboveground installations (Land Use/Building Consent conditions etc.). If installed above ground, the tank
needs to be protected against UV radiation, for example by painting it with UV-reflective paint.
Available tank sizes are 3000 L and 4000 L. Both tanks have the same bed configuration and provide
the same treatment capacity and performance, but use different inlet invert depths as follows:
•
•
BF6-3000 tank: 650 mm
BF6-4000 tank: 1100 mm
Effluent Discharge
The BF6 effluent is either gravity drained or pumped to a dispersal system. The pumpout (dose)
volume is 220 L per cycle. The standard pump is a high-quality Pedrollo NKm 2/1 submersible pump,
the characteristics of which are shown in Figure 2 below. Other Pedrollo pumps may be used instead
to suit specific sites. Contact Biolytix to discuss your requirements and for information on the types of
pumps available.
Figure 2 Pedrollo NKm 2/1 characteristic curve (power 0.45 kW)
Alarm System
The BF6 is equipment with an AS/NZS 1546.3 compliant Audio/visual alarm using a mutable audible
signal and an alarm light. The alarm plate is typically mounted in a visible location within the dwelling.
Alarms are triggered by a high-level float switch in the pump well, an air pressure switch on the air
supply line or if the power supply to the Biolytix tank is interrupted.
