Whitesales is
renowned for proven
product ranges,
industry leading levels
of service and expertise.
Why is natural daylight so important?
Natural daylight has long been recognised as the most
effective form of light. Building Regulation Approved
Document L requires designers to provide adequate
daylight ‘...where rooflight areas are reduced below
20%, the building designer must take special care to
demonstrate daylight levels remain adequate...’
Flat roof rooflights are the most efficient means of
providing natural daylight, providing up to three times
more daylight than an equally-sized vertical window.
The light from a rooflight is also more evenly distributed
throughout the room, less likely to result in glare or
compromise of privacy.
Natural daylight is an invaluable natural asset.The benefits
of a naturally-lit workspace are well documented and include
increased productivity, work satisfaction and cost reduction,
as well as significant reduction of impact to the environment.
From a building design perspective the use of rooflights is an
excellent means by which both light and solar energy can be
utilised to save energy and to reduce the carbon footprint of
any property.
There are specific industry policies and guide documents
to assist with introducing naturally-lit space into different
building types (especially schools).Whitesales can offer support
and advice on the requirements for specific applications.

Em-Dome
®
Em-Dome in opal diffused with
300mm PVC upstand and rotating vents
Em-Dome pyramid in opal diffused with Em-Curb PVC 300
High quality thermoformed rooflights designed to make
optimum use of natural light. Em-Domes are offered in a
wide range of sizes, shapes and glazing options to meet
virtually any specifier and client requirement.
Description
High security screwbolts
Em-Dome rooflights are thermoformed from UV protected,
co-extruded polycarbonate sheet and are available in single,
double, triple, quad skin or Eco multiwall construction.
Unique to the Em-Dome are the patented high security
screwbolts, supplied factory fitted as standard to all units.
Once installed, the fixing cannot be removed using common
tools. The screwbolt provides a high level of resistance to
tampering or forced entry. The fixing screw or bolt is sleeved
within the body of the screwbolt which avoids pressure being
exerted on the rooflight glazing as the fixing is tightened.
This virtually eliminates the risk of stress fractures caused
by over-tightening.
Polycarbonate Em-Domes use a minimum 3mm thick glazing
and have been tested and certified according to EN 1873:
1200 Joules, and ACR(M): 001: 2005 Class B.
Em-Domes are tested to the highest standards and are proven
suitable for use on most flat roofs, including single ply, felt,
hot-melt, asphalt, liquid, GRP and lead. They are normally
specified with our proprietary curbs (see page 10) but can also
be installed on existing builder’s curbs.

Em-Collar adaptors
Em-Dome linked double units with Em-Collar and aluminium cowl
Em-Collars provide a thermally broken solution for replacing
existing rooflights and would typically be installed to an
existing builder’s upstand. Consideration should be given
to using the PVC 350/s upstand to oversleeve existing site
upstand as this reduces site work, especially where existing
linings must not be disturbed, e.g. may contain asbestos.
T-Collar adaptors, collars and flanges
T-Collars are purpose made to fit any size or type of existing
builder’s curb or proprietary upstand and enable Em-Domes
to be fitted where existing dimensions are irregular or a
direct size match is not available.
Em-Collars and T-Collars are a flexible solution and can
also incorporate all ventilation, access hatch and smoke
vent options.
Em-Collar PVC Adaptor Collar
Em-Collar PVCu 150mm high
Multiple Em-Dome rooflights
For extra long applications, e.g. 3 to 6m, two or more
Em-Domes can be installed together by means of linked
T-Collar adaptors. These are self-supporting up to a span
of 1m. For spans over 1m a structural support will be
required. Where necessary, linked T-Collar adaptors are
supplied in individual sections for jointing on site, utilising
a standing seam detail.
Aluminium cowl
Em-Curb upstands can also be used in conjunction with
multiple rooflights.
For roof openings longer than 6m, we would normally
recommend a continuous barrel vault rooflight (refer
to the Whitesales ‘Continuous rooflights’ brochure).

Description
Where the rooflight is to be used as a means of access on
to a roof the hinged access hatch frame opens to 90° to provide
a safe route for personnel and equipment, often avoiding the
need to provide other external facilities. The access frame can
be specified for mounting either direct to a builder’s curb with
Em-Collar and T-Collar adaptors or in conjunction with Em-Curb
upstands.
Standard features include a locking handle to secure the
rooflight in the closed position and telescopic struts to hold
the rooflight in the open position. The telescopic struts are
either gas assisted hydraulic operation or have adjustable
friction control and can be set according to dome weight
and prevailing site conditions.
Limitations of use
Access hatches are not recommended in sizes larger than
1160mm square or 860 x 1460mm rectangular.
Other options
Remote electric operation opening units are also available
(refer to Whitesales).

OVs (Opening Vents) and AOVs (Automatic Opening Vents)
are required to meet the relevant Building Regulations for
ventilating escape routes. The Regulations stipulate a minimum
free ventilation area (normally 1.0m2 or 1.5m2), and require units
to open to either 90° or 140° depending on a number of factors.
Ventilation areas can be achieved with a variety of square or
rectangular Em-Domes and can be used in conjunction with
Em-Curb upstands or T-Collar and Em-Collar adaptors.
Opening the rooflight is by means of a 24V DC electric actuator.
For OVs we can provide a stand alone control panel with a
comprehensive range of accessories – for AOVs our control
panel can interface with the main Building Management
System (BMS) or accessories. Due to the variety of BMSs that
are required to satisfy the relevant authorities, we recommend
that a qualified mechanical and electrical company is employed
to plan and install the system.

Where natural ventilation is insufficient, Em-Domes
can be supplied with Vent Axia Solo or Centrif Duo centrifugal
extract fans. These are mounted in the side wall of Em-Curb
PVC-u 150/v or Em-Curb PVC-u 300/s.
These high performance extract fans are specifically designed
for ventilating internal bathrooms, WCs and other small
rooms. They have an extract performance of 85 m3/hr (24 l/s)
or 220 m3/hr (61 l/s) respectively and can be fitted in one or
more sides. Where greater air movement is required, white
PVC lined fan collars with pre-cut apertures are available to
enable fitting of larger axial fans (e.g. Vent-Axia T-series).
This allows either new high capacity fans to be installed or
existing fans to be reinstalled through the rooflight unit.

Em-Glaze
™
Em-Glaze Modular to builder’s upstand
Em-Glaze Modular with insulated T-Collar
High quality, aesthetically pleasing prefabricated flat glass
rooflights. Em-Glaze Modular units are available in a wide range
of standard sizes or can be made to measure and can also be
colour coated to match other roof components if required.
Description
Performance
Em-Glaze Modular rooflights are designed to maximise the
amount of natural daylight in a building and at the same time
provide a clean minimalistic finish both inside and outside.
They are manufactured with flat sealed glass units and
incorporate a fully welded aluminium frame and cill detail.
All visible aluminium is polyester powder coated light grey
as standard.
Thermal regulations
The flush design ensures efficient drainage of rainwater and
the silkprint edge ensures that the double glazed unit holds
the unrivalled insulation value over the full lifetime without
deterioration.
The double glazed unit exceeds current thermal requirements
and the triple glazed unit gives an industry leading
performance.
Sound reduction
With glass panes each at 6-8mm thick and a 16mm argon filled
cavity the sound reduction will give excellent protection from
traffic or other noise.
Installation
As the units are supplied prefabricated and assembled they
are very simple to fix, either to a site formed upstand or to
one of our PVC proprietary Em-Curbs.
Certification
Impact resistant to CWCT Class 2.

Em-Tube
™
After Em-Tube installation
Before Em-Tube installation
Em-Tube with PVC 150mm upstand on flat roof
Em-Tube Tubular Skylights effectively transmit natural daylight
to internal rooms or areas that do not receive adequate daylight.
Natural daylight is captured at roof level and directed downwards
through rigid or flexible tubes and then diffused at ceiling level.
Flat and pitched roof tubular skylights
How much light does Em-Tube transmit?
Many buildings suffer from low levels of daylight. Occupants
and workers in all types of building, e.g. residential and
commercial buildings, schools and hospitals all benefit from
increased levels of natural daylight.
Tests carried out in the UK prove that anything up to fourteen
times the equivalent of a 100 watt bulb can be achieved with
3m of flexible Em-Tube run on the 550mm diameter unit.
Natural daylight in buildings reduces energy demand and
provides the full colour spectrum, thus reducing eyestrain,
improving concentration and increasing productivity.

Description
Applications and limitations of use
Em-Tube is an innovative and effective means of transmitting
natural daylight to otherwise poorly lit areas. A passive
ventilation system is included as a standard option and is
available in rigid and flexible tube systems.
For maximum daylight output the Em-Tube should be located
on a south facing roof slope and/or as high as possible, out of
any shadow of tall trees and buildings. It should also be
installed to give the most direct run from roof to ceiling level.
Rigid tube system
No specific level of light transmission can be guaranteed
because specific applications and external light conditions are
beyond our control.
Offers 98% reflection on inner surface. Up to 20 times more
light (2200 lux) than a 100w bulb (105 lux). Suitable for longer
tube lengths.
Tile Flashing Kits are available to suit plain/profiled tiles or slates:
Provides up to 14 times more light (1500 lux) than a 100w bulb
(105 lux). Suitable for shorter tube length and is easier to install.

Design considerations
contribute to an overall reduction in CO2 emissions in most
buildings. Rooflights are up to three times more effective at
supplying daylight than vertical windows. Where artificial lighting
is controlled by daylight sensors, installing rooflights can result in
a significant reduction in the energy used for lighting. Energy
consumed in lighting a building is often greater than that used to
heat it. In addition, the SAP and SBEM software programs take
account of the contribution made by passive solar gains through
rooflights. Solar gains help to offset the increased heat loss of
rooflights compared to the insulated main roof.
Air permeability
Whitesales is able to advise on current requirements and regulations.
The following pages summarise some of the key considerations
that should be taken into account when specifying rooflights.
Approved Document L 2010:
Conservation of fuel and power
Introduction
This Approved Document, which takes effect on 1 October 2010,
deals with energy efficiency requirements in the Building
Regulations (as amended) and is made up of four distinct
publications which are summarised below. It should be noted that
Approved Documents are guidance publications and there is some
provision for trade-off with other building elements – any proposal
should be checked with the relevant building control body. U-Values
should be calculated in accordance with BRE 2006. The document
also covers areas such as Materials and Workmanship including
a requirement to demonstrate appropriate use of products with
CE marking, British Standards and European Technical Approvals.
Whitesales Em-Dome rooflights have undergone stringent and
extensive testing and are certified to these standards.
Solar heat gain
Approved Documents L1A and L2A include requirements to limit
solar gains through the summer period. The inside of the building
can heat up during daylight hours due to the sun. This is termed
as solar heat gain. To reduce this effect, solar control glass can be
adopted to reflect heat and reduce glare from the sun’s rays. This
lessens the burden on air-conditioning systems thus reducing CO2
emissions. In simple form, this may be body tinted glass in blue,
green or bronze or more sophisticated, coated clear glass that
allows maximum light transmission, but at the same time
substantially reduces heat gain. For Em-Dome values, see page 9
of this brochure – Solar heat gain factor (g%).
Optimum rooflight provision
A building’s design will affect the contribution rooflights can make.
The optimum area of rooflights will therefore vary for each building.
However, research has shown that a rooflight area of 15-20% will
36
Air permeability is the physical property used to measure airtightness
of the building fabric. It is defined as air leakage rate per hour per
square metre of building envelope at the test reference pressure
differential across the building envelope of 50 Pascal (50N/m2). The
limiting air permeability is the worst allowable air permeability. The
design air permeability is the target value set at design stage, and
must always be no worse than the limiting value. The assessed air
permeability is the value used in establishing the BER, and is based
on a specific measurement of the building concerned.
ADL 1A: New dwellings
This document sets a minimum energy performance
requirement called the ‘Target CO2 Emission Rate’
(TER), and ‘Dwelling CO2 Emission Rate’ (DER). The
aim is to improve the overall building envelope rather
than specific elements hence improvements in one
area can be used to offset other areas of poorer
performance. Section 4.20 covers ‘Window, roof window, glazed
rooflight, curtain walling and pedestrian door’. Specifically rooflights
must conform to a U-value of no more than 2.00W/m2K and the
calculation is based on the value of the complete rooflight unit
rather than the values of any one component part.
ADL 1B: Existing dwellings
Section 4.19 covers ‘Window, roof window or
rooflight’ The document states that where windows,
roof windows or rooflights are to be provided, the
reasonable provision – in normal cases – would be
the installation of draught-proofed units whose
performance is no worse than a U-value of 1.6W/m2K
or complying with the Window Energy Rating System, B and C.
ADL 2A: New buildings other than dwellings
This document sets a minimum energy performance
requirement called the ‘Target CO2 Emission Rate’
(TER), and ‘Building CO2 Emission Rate’ (BER). The aim
is to improve the overall building envelope rather
than specific elements hence improvements in one
area can be used to offset other areas of poorer
performance. Section 4.30 covers ‘Window, roof window, glazed
rooflight, curtain walling and pedestrian door’. Specifically rooflights
must conform to a U-value of no more than 2.2W/m2K. The
calculation is based on the developed area of the rooflights rather
than the roof aperture and is the value of the complete rooflight
unit rather than the values of any one component part. Also
included are ‘Roof ventilators (inc. smoke vents)’ which must
conform to a U-value of no more than 3.5W/m2K.
ADL 2B: Existing buildings other than dwellings
Section 4.23 covers ‘Window, roof window and glazed
rooflight’ and ‘Plastic rooflight’. Specifically plastic
rooflights must conform to a U-value of no more
than 1.8W/m2k. Also included are ‘Roof ventilators
(inc. smoke vents)’ which must conform to a U-value
of no more than 3.5W/m2K.
Approved Document B 2006: Fire Safety
Approved Document B places certain limitations on
the use of rooflights, which are dependent on glazing
material and site circumstances, such as building size,
use of area below rooflights, rooflight size and
proportion of total roof area, distance from boundary
etc. The relevant information is set out in Volume 1:
Sections 3 and 10; Volume 2: Sections 6, 12 and 13 of Approved
Document B, 2006 Edition. Where applicable, the responsibility
for determining that any building component complies with the
relevant Regulations rests solely with the customer or specifier.
Approved Document E 2003 (amended):
Resistance to the passage of sound
This document requires that buildings are designed
and constructed to provide resistance to sound and
reverberation. The aim is to limit noise disturbance by
including sufficient acoustic properties and insulation
in areas such as internal and external walls, floors and
other elements. Rooflights should perform in
accordance with these requirements and the decibel reduction
value can be used in calculations for this purpose. For Em-Dome
acoustic values see page 9 of this brochure and for Em-Glaze
Modular see page 24. Further information is available in Building
Bulletin 93 – Acoustic Design for Schools.
Approved Document F: Means of ventilation
This document places the responsibility on the
designer to comply with ventilation requirements
to new and existing buildings. It states ventilation
types including extract, whole building and purge
and gives minimum ventilation requirements.
Rooflights are often a useful means of complying
with the requirements especially where no other external aperture
is available. See pages 16-18 of this brochure for Em-Dome
ventilation options. Further information is available in Building
Bulletin 101 – Ventilation of School Buildings.
BS 6229
BS 6229: 1982, Code of Practice for flat roofs with continuously
supported coverings, requires rooflights to incorporate upstands to
raise them at least 150mm above the uppermost roof surface to
which the roof covering is bonded or dressed. The designer should
ensure that the builder’s curb is at least 150mm high.
BRE BR443
Various standards deal with the calculation of U-values of building
elements. The conventions provide guidance on the use of the
standards, indicating the methods of calculation that are
appropriate for different constructional types, providing additional
Rooflights are up to

information about using the methods and providing data relevant
to typical UK constructions. The U-value conventions were originally
published by the BRE in 2002 and the 2006 edition is an update
which provides additional information and reflects changes in the
underlying British Standards. The U-Value calculation methods are
also referred to in Approved Documents L1A, L1B, L2A and L2B.
Condensation
Condensation occurs where warm moist air meets cold surfaces.
As warm air rises, the risk of condensation forming at rooflight level
is relatively greater than at lower level. The risk can be minimised by
specifying triple skin Em-Domes and Em-Curb insulated upstands.
The provision of ventilation may also assist (see options on pages
16-18). However, because temperature and humidity levels are
clearly beyond our control, no guarantee can be given against the
formation of condensation.
Condensation between the skins can also occur when the room
below has high humidity levels, for example during construction
from new plaster or paintwork. Polycarbonate is hygroscopic and
allows water molecules to filter through – the water pressure forces
its way through the lower skin and condenses inside the cavity.
However, once the humidity level in the room is restored to normal
this condensation dissipates through the breathable seals.
Limitations on use
Whitesales modular rooflights are designed for use in normal
circumstances on flat roofs up to 15° pitch (on flat roofs Em-Tube
can be used up to 15° and on pitched roofs above 15°). For
applications in excess of 15° or in unusual circumstances (e.g.
extreme temperature or climatic conditions) please refer to
Whitesales. Please note that all information supplied is based on
our best knowledge and general experience. Because of factors
outside our control which can affect installation and use of
products, no warranty is given or implied in respect of information
provided. A policy of continuous product improvement applies and
Whitesales therefore reserve the right to alter specifications
without prior notice.

Health & Safety
For specifiers the key message is to eliminate ‘fragile’ materials
from roof design. For contractors, provide effective fall arrest
equipment or safety netting.
Non-fragile rooflights
Whitesales Em-Dome rooflights are out-of-plane rooflights,
and provided they are specified with polycarbonate glazing,
can be deemed to be ‘non-fragile’.
Polycarbonate Em-Domes have been independently
tested according to EN 1873 2005 [E] to an energy of 1200J
and to ACR[M] 001: 2005 and can be classified as Class B
‘Non-Fragile’.
Whitesales offers a 10 year warranty against discolouration
of Em-Domes glazing material and, in the case of
polycarbonate, loss of impact strength underwritten by
the sheet material supplier.
Whitesales polycarbonate Em-Domes have been awarded
BBA Certification or are manufactured to ISO 9001.
Construction (Design & Management)
Regulations 2007
According to the Health and Safety Executive, almost 20%
of deaths in the construction industry are caused by falls from
or through roofs. The majority of these falls are through fragile
materials such as asbestos cement roofing or old/fragile
rooflights.
The Construction (Design and Management) Regulations 2007
places a duty on designers and specifiers to give proper
consideration to eliminating or reducing risks at the design
stage. Health and Safety Executive (HSE) Health and Safety in
Roof Work draws attention to the responsibilities of those
specifying rooflights.
(HSE) Health and Safety in Roof Work states that where
rooflights are required, designers should consider:
Specifying rooflights that are Non-Fragile.
Fitting rooflights designed to project above the plane of
the roof and which cannot be walked on (these reduce the
risk but they should be capable of withstanding a person
falling onto them).
Protecting rooflight, e.g. by means of mesh or grids fitted
below or above the rooflight
Specifying rooflights with a design life that matches that
of the roof, taking account of the likely deterioration due to
ultraviolet exposure, environmental pollution and internal
and external building environment.
38
Whitesales offers a post-forming warranty backed by the
sheet manufacturer.
Man-safe
Man-safe is a term often used within the construction industry
to mean that the product can withstand foot traffic. However
man-safe has no recognised definition and ‘non-fragile’ does
not qualify a product to be used as a thoroughfare.
Whilst glazing and other accessories may be designed to safely
resist the impact of a human body falling against it, the wilful
act of walking on any kind of roof glazing must be forbidden
at all times.
The act of walking upon a glazed structure can cause
microscopic damage that, in time, may have a detrimental
effect upon the impact performance of the system.
Walking upon glazing may encourage a practice that could
lead to general disregard for the rating of said glazing, with
catastrophic consequences.
Safety data sheets are available on request.
Sitework
Handling and storage
While all Whitesales modular rooflights and associated
products are suitably packaged to avoid damage care should be
exercised when handling. For moving larger items, two or more
people may be needed. All products should be stored on edge in
flat dry conditions.
Installation
Fixing Em-Domes to Em-Curbs
The Em-Dome should be accurately positioned on the Em-Curb
and the screwbolt fixing positions marked on the Em-Curbs.
The fixing holes are drilled in the Em-Curb and the Em-Dome
is simply placed in position and fixed using the screwbolt
fixings supplied.
All Em-Dome and Em-Glaze rooflights are supplied ready
assembled and pre-drilled complete with security screwbolts
and factory applied sealing tape where applicable and are
delivered to site in protective packaging. Full instructions and
fixings are included with all products, and should be carefully
studied prior to installation.
Overall rooflight size
Daylight size
Fixing upstand curbs
For fixing curbs to the roof structure, drill holes in the bottom
flange, 100mm from each corner and at maximum 300mm
centres and screw to roof structure. Typical installation details
are shown below. The PVC-u Em-Curb is suitable for use with
most flat roof systems including single ply, felt, hot-melt,
asphalt, liquid and lead.
Where asphalt is specified, Whitesales recommend the use of
PVC-u upstands with pre-fixed sheathing felt and expanded
metal lathe. This must be specified if required.

Fixing Em-Domes to builder’s curbs
The Em-Dome overall rooflight size should be 60mm bigger
than the outside dimensions of the upstand curb. Holes should
be pre-drilled in the upstand curb to accept the tamper-proof
screws provided for use with the screwbolt fixings. The fixing
positions can be located by accurately placing the dome over
the upstand curb, with the screwbolt caps removed, and
marking the position of the fixings.

Environment
Our responsibility
Environmental policy
The environment and the effect we have upon it is one of the
key issues facing the construction industry.
In maintaining and developing our business, products and
services, we will pay careful attention to the following
measures:
There is a growing demand for construction solutions which
minimise the consumption and use of natural resources.
Whitesales recognises the impact that we can have on the
environment and is managing activities to maximise our
contribution towards the protection of the environment
and preservation of natural resources. This includes constant
reviews of our manufacturing operations and distribution chain.
Sustainability
Sustainable developments ensure a better quality of life
for everyone, now and for future generations. To be
environmentally sustainable a product must be manufactured
and used in a way that minimises its impact on the
environment.
Sustainability covers all aspects of a product’s impact on
the environment. This includes original source of raw materials,
the manufacturing process, transportation, construction, life
span of the product and eventual disposal and re-use of the
material.
Comply immediately with all applicable laws and
regulations concerning the environment.
Develop manufacturing processes and operational
procedures that minimise, as far as practically possible,
pollution risks to the environment.
Reduce waste generated by our activities and encourage
energy conservation, recycling and re-use.
Provide training and support to employees to enable
them to maximise their contribution towards the
protection of the environment.
Encourage suppliers, contractors and customers to share
in our aims to promote good environmental management.
