GTEC® SYSTEMS FOR HEALTHCARE
SYSTEMS FOR
HEALTHCARE
GTEC Plasterboard Systems have been used extensively in major
healthcare projects across the UK and Ireland as fast and effective
solutions to healthcare construction.
The GTEC Boards and GTEC Systems have been developed to meet
and exceed the full range of extraordinary demands placed on
hospital and healthcare buildings.
EXTRAORDINARY DEMANDS
ACOUSTICS:
The acoustic demands on partitions in Healthcare buildings are extreme; from
ensuring consultation room privacy and operation suite concentration, to
dealing with emergency vehicle sirens and the intensity of A&E departments.
While layout can ease noise risk, GTEC Systems allow for flexible design with
extremely high levels of sound insulation from space to space. The partition
performance ensures that a superior healing environment is achieved. GTEC
Pregybel ceilings also help to control noise levels through acoustic absorption.
FIRE:
Multi-storey constructions containing bed-bound patients, large public areas,
multiple service entrances and numerous circulation routes, place a high fire
resistance demand on any project.
GTEC Partitions and GTEC Ceilings provide a simple design with high levels
of fire resistance and robust detailing for design flexibility. GTEC Shaftwall
and GTEC Encasement Fire Protection solutions offer specialist passive fire
protection to lifts, shafts and structural steel.
IMPACT:
Hospitals are dynamic, highly trafficked, public environments where walls are
subject to constant impact from staff, visitors and hospital equipment.
GTEC LaDura, a unique and exceptionally strong plasterboard, achieves severe
duty ratings with the minimum of boarding. Plus, it provides high levels of
fixing resistance for crash rails, skirting, services and fixtures.
HYGIENE:
Easy to clean surfaces are vital for good healthcare environments which need
frequent washing, and are dependent on excellent hygiene.
GTEC Finishing solutions combined with GTEC Partition and Lining systems
offer smooth, easy to joint and repairable surfaces which are easier to clean.
GTEC Megadeco Board requires no pre-sealing for even faster finishing.

GTEC® SYSTEMS FOR EDUCATION
SYSTEMS FOR
EDUCATION
GTEC Plasterboard Systems have been adopted in hundreds of
school, academy, college and university projects across the UK and
Ireland to efficiently meet the needs of education construction.
The range of GTEC Board and GTEC Systems suit the full scope
of extraordinary demands placed on education buildings.
EXTRAORDINARY DEMANDS
ACOUSTICS:
From music and sports noise to examination room silence, Education buildings
place extreme acoustic demands on specification. The isolation and control
of ambient noise from space to space is vital, as is good speech clarity in open
spaces, along with controlled reverberation.
While layout design can reduce noise risk, GTEC Systems’ high level of sound
insulation allows design flexibility from space to space. GTEC Pregybel ceilings
offer acoustic absorption and echo control, improving speech clarity and
reducing noise distractions.
FIRE:
“Each year around 1 in 20 schools experiences a fire and nearly 60% of school
fires are started deliberately.” BB100
Large circulation areas, multi-storey construction and broad types of use from science
labs to sports halls place a high fire resistance need on any Education project.
GTEC Partitions and GTEC Ceilings achieve high levels of fire resistance
with uncomplicated, robust and proven detailing for design flexibility.
GTEC Shaftwall and GTEC Encasement Fire Protection solutions offer
specialist passive fire protection to lifts, shafts and structural steel.
IMPACT:
Education buildings face some of the most intense usage. With high levels
of student movement, a wide variety of activities taking place and the chance
of misuse, careful specification is needed to reduce maintenance and repairs.
GTEC LaDura Board is exceptionally strong and achieves severe duty ratings
with the minimum of boarding. It offers excellent impact performance for
corridors and high levels of fixing resistance for fixtures and fittings.
DESIGN:
An innovative design can transform the learning experience of students,
enhancing their performance, motivation, behaviour and engagement.
Ideal for the most ambitious projects, GTEC Systems are flexible,
high performance and easy to install, providing quick construction.
GTEC LaDura, Aqua Board and Megadeco take plasterboard systems
to new areas replacing slower, less flexible, wet construction methods.

GTEC® SYSTEMS FOR RESIDENTIAL
SYSTEMS FOR
RESIDENTIAL
GTEC Plasterboard Systems have been used across the UK and
Ireland to successfully build or renovate thousands of housing,
apartment and hotel projects.
The diverse range of GTEC Board and GTEC Systems features solutions
ideal for the construction of homes and other residential buildings.
EXTRAORDINARY DEMANDS
ACOUSTICS:
Busy lifestyles, close neighbours and urban noise can all combine to affect the
quality of home life. Party walls, party floors, partitions and ceilings all require
special attention to reduce noise issues.
GTEC Systems are tested to achieve extremely high levels of sound insulation.
They meet Part E Regulations and the enhanced CSH (Code for Sustainable
Homes) requirements* with the minimum of components.
*+3dB and +5dB over Part E for separating elements (Code for Sustainable Homes Technical Guide – November 2010)
FIRE:
With occupants of all ages, most often present at night while asleep, a
fire resistant design is essential. Multi-storey buildings and their escape
routes present even greater fire resistance needs, as stipulated by Building
Regulations Part B – Fire Safety.
GTEC Partitions and GTEC Ceilings achieve a full range of fire resistance using
minimal components for multi-storey apartments, dense housing developments
and detached houses. Robust and proven detailing enables design flexibility
and economic construction.
SUSTAINABILITY:
Dwellings are responsible for up to 30% of national carbon emissions through
their construction and use. Huge changes to the Building Regulations, as well
as the Code for Sustainable Homes (CSH), have been implemented to reduce
these carbon emissions representing a major shift in construction methods.
The use of GTEC Systems can earn CSH credits in a variety of ways – for more
details see the Sustainability section on pages 336-340. GTEC Systems are made
up of fully recyclable components with gypsum plasterboard being 100% re-usable
in a closed loop process. Recent product innovations use minimal components to
achieve technical performances, limiting material usage and waste.
All GTEC Lining systems can provide insulation to enhance the thermal
performance of external walls. These include the GTEC Thermal Boards range;
thermally laminated plasterboards which are recommended by Approved
Document L1B to achieve thermal upgrades in renovation projects.

From over 25 years of experience on building sites we know
there is unmet potential in drywall and have created the
boards to unlock it.
Excellent fire and acoustic performance is always
expected and we have the range of boards with
higher densities, highly developed additives and
patented technology to achieve the top levels
of fire and sound performance needed in the UK
and Ireland.
But we don’t consider that to be enough. Better
finishing capabilities are available. As a result we
are the first and only manufacturers of gypsum
plasterboards which offer exceptional water
resistance, exceptional strength and exceptional
finishing speed.
We also know that one board can do more than
one thing. Our boards combine the highest levels
of performance making them suitable for a huge
breadth of applications, reducing the amount
of fixing, and potentially meaning only a single

SYSTEM SOLUTIONS
Each of our three unique boards elevates the final layer of the partition,
ceiling or lining, to previously unknown levels of standard plasterboard
construction. These capabilities drive a different ethos in specifying
drywall systems – the basic demands of acoustics and fire are always
achievable and the focus can now switch to these extra benefits.
Good design means every space has its own needs and tuning boards
to best suit these demands is made possible.
FROM TWO BOARDS TO ONE
OPPOSING NEEDS
For many performance requirements the
board configuration can be improved with
Siniat products, from two layers of a lower
spec board to just one layer of a board such as
GTEC Megadeco or LaDura. This can drastically
reduce the number of boards needed on
site. One high performance technical board
can often do the job of two standard boards.
Installation time is reduced without having to
fix multiple layers, there is less waste as material
volumes are reduced and the whole project
becomes simpler to specify and manage.
Great architectural design will not always
place identical rooms on opposite sides of a
partition. With Siniat systems this problem is
solved with hybrid system make-ups giving
different finishing performance on each side of
the partition. For example, a partition between
a shower room and a corridor in a school could
use GTEC Aqua Board on one side and GTEC
LaDura for the corridor side. The lower of the
two corresponding performance values for
sound or fire being would be used unless the
system has been tested in a hybrid make-up.

SYSTEM PERFORMANCE
SYSTEM
PERFORMANCE
FIRE
Gypsum is a naturally fire resistant material, locking in water which will
be released during a fire. This water controls the temperature allowing
plasterboard systems to survive a fire for substantial lengths of time.
The requirement for fire protection in a project is
driven by the Building Regulations, fire strategy
and any high risk equipment or activity in a
building. The ratings in this manual represent
the minimum passive fire protection that
can be expected in a fire and can be used to
show compliance with the current Building
Regulations in the UK and Northern Ireland.
The fire ratings of the systems are determined
by testing and assessment to British and
European standards. In the UK the BS 476
series of test standards and BS EN 1361, 1362,
1363 standards are used to establish the fire
resistance of building elements such as walls
and ceilings. A different temperature monitoring
method is adopted in the European test methods
and the results obtained are not the same
as the British Standard results; both results
are declared in this manual where possible.
The tests are carried out in 3m x 3m aperture
furnaces which simulate the most intensive
period in a fire. The results of these tests are
expressed in terms of integrity, insulation and
loadbearing capacity (where applicable).

SYSTEM PERFORMANCE
ACOUSTICS
Control of sound in buildings is essential for comfort. Plasterboard systems
can assist with acoustic requirements in two ways, through sound insulation
and sound absorption. Sound insulation is principally driven by the surface
mass of a building element. As a thin, dense material plasterboard can be
used to provide adaptable solutions for minimising sound transmission.
Plasterboards generally reflect sound, however, perforated boards enable
effective sound absorbing systems to be built.
For residential construction the Building
Regulations contain minimum values for sound
transmission between rooms and absorption
within communal areas. For many other
projects acoustics are beyond the remit of
building regulations. It is essential to consider
the noise tolerance and noise output of
neighbouring spaces to select the right levels
of sound insulation for the separating element,
consultation with acousticians is recommended.
The sound insulation values quoted in this
manual use consistent laboratory testing to allow
system comparison. Elements are placed in an
aperture between spaces with the reduction in
sound pressure between the two spaces being
recorded; this testing is carried out to BS EN
ISO 140 and BS EN ISO 717 standards. The result
is the Weighted Sound Reduction Index (Rw)
measured in decibels (dB) with higher values
offering better insulation.
Site testing uses a different measurement
method of Standardised Level Difference (DnT,w)
where values around 7dB lower than laboratory
tests can be expected. It is critical to seal all
air paths, avoid routes for sound to ‘flank’ the
element and build to high standards to achieve

Sound absorption is calculated through laboratory
testing to European and ISO standards where
a component is located in a space with known
reverberation – the resulting reduction in
reverberation time gives a coefficient of sound
absorption. This co-efficient varies between 0
and 1 with higher values representing greater
absorption per square metre.

SYSTEM PERFORMANCE
STRUCTURE
A major advantage of plasterboard systems is their low mass to height/span
ratio, this enables tall partitions and wide spans to be created without imposing
high loads on structures supporting the system. As a lightweight system overall
robustness must be considered and by using the correct framework and board
combinations extremely tough partitions, ceilings and linings can be built.
The maximum height of a partition is determined
from its ability to resist a uniformly distributed
lateral pressure, taken as 0.2kN/m2 for most
internal applications, and limiting the resulting
deflection to height/240. Greater lateral pressures
and other imposed loads are possible and depend
on the layout adopted. The ‘Strength’ criterion
in the System Performance Tables is determined
according to the test methods and criteria
given in BS 5234-2. There are four grades in the
standard, increasing in robustness from Light,
Medium, Heavy to Severe Duty. In most projects
the use of the lowest duty grade will result in
walls which are too flexible for the expectations
of users and are not generally recommended.
Based on extensive testing and calculations
the height values shown in this manual are the
maximum that the system can safely satisfy
when fully built. Care must be taken during
construction to ensure that the construction
sequence does not undermine structural
strength and construction loads are not
applied to the systems.
The ceiling systems in this publication will not
support imposed loads in addition to those
given in the appropriate sections. Fixings to
structural elements must be determined by
suitably qualified professionals and are not the
responsibility of Siniat.
GRADE

SYSTEM PERFORMANCE
THERMAL
Plasterboard is not a low conductivity material but can be combined easily with
different types of thermal insulation to create systems or products (such as GTEC
Thermal Boards) which offer excellent thermal insulation properties. Plasterboard
systems can contribute to construction with the most thermally efficient U-values
satisfying new build or renovation building regulation requirements.
Plasterboard is dimensionally stable and can be
ideal as the air-tightness envelope in a building,
with projects typically achieving 3m3/hr/m2
@ 50Pa, exceeding the building regulation
requirement. The stability of plasterboard
systems also allows construction independent
of the substrate to prevent thermal bridging.
this manual so it is often possible to achieve
improved U-values by changing the quality
and quantity of insulation, contact Technical
Enquiryline for further information.
The U-values quoted in the system performance
tables can be used in SAP and SBEM calculations
either as part of an external element or as
the whole element where no other material
is involved. For thermal upgrades to existing
dwellings the default U-values for construction
types and ages found in RdSAP 2009 have
been used to indicate a resulting U-value with
GTEC products and systems. Only a select range
of systems configurations can be shown in
TYPICAL U-VALUES
FOR PART L 2010
U-values are calculated, following the
conventions of BR 443, using specialist
calculation software, from conductivity values
in international standards or manufacturers’
information. In product reference tables the
quoted conductivity values (λ) W/mK for the
materials in specific products have been used
to calculate the thermal resistance (R) mK/W
for that product. The GTEC range does not
include independent insulation and therefore
U-values should always be checked against
manufacturer’s data for the actual insulation
used in construction.

PARTITION PERFORMANCE NOTES
Performance values are for imperforate, jointed systems using Siniat GTEC components (metal studs and tracks, boards, metal accessories,
screws and finishing systems) and specified insulation quilt material (type, thickness and density) and installed to Siniat specification and
installation guides.
Any alterations may impair the quoted performance. Contact Technical Enquiryline for further system configurations and their resulting
performances.
All maximum heights are based on a maximum partition deflection limit of height/240 at the stated duty ratings under a uniform lateral
pressure of 0.2 kN/m2 and can be increased using thicker gauge studs.
Maximum height can be increased by 0.3m for single layer boarding and by 0.6m for double layer boarding when studs centres are
reduced to 400mm.
The maximum partition height may vary from the quoted values if the fire resistance of the system is specified according to BS EN 1364-1.
Insulation shown may be replaced with thicker and/or heavier quilt material without impairing the quoted performances.

GTEC® C STUD PARTITION
®
GTEC C STUD
PARTITION SYSTEMS
GTEC Metal Stud Partitioning is an economical, friction-fit system for
assembling internal partitions. The unique design of the components
ensures high strength, easy installation and a higher performing
alternative to traditional timber frame partitions.
GTEC C Stud Partitions are constructed using a frame of GTEC U Track
at the head and base with GTEC C Studs for vertical framing elements.
A range of GTEC C Stud and U Track widths allow varying partition
depth, enhancing fire resistance, sound insulation and maximum
heights. For individual system performances, refer to the System
Performance Tables on pages 22 to 44.
WHERE TO USE:
GTEC C Stud Partitions create internal dividing walls within both
domestic and commercial projects.
FEATURES
BENEFITS
Strong
Less material is required than a similar timber
frame structure
Lightweight
Multiple lengths can be carried at one time
Natural resistance to bowing, bending and
insect infestation
Metal maintains shape, removing the chance of
‘screw popping’
High fire resistance levels
Fire performance levels are easily achieved
using metal
High acoustic performance levels
Acoustic performance levels are easily achieved
using metal
Flat finish
Provides an easy surface for decoration
GTEC® C STUD PARTITION
TIP: Partition heights can be increased with additional studs,
e.g. with studs boxed, back-to-back, at closer centres or
thicker stud gauges.

GTEC® ACOUSTIC STUD PARTITION
®
GTEC ACOUSTIC STUD
PARTITION SYSTEMS
The GTEC Acoustic Stud is an alternative to 70mm, 90mm and
146mm GTEC C Studs, where higher levels of acoustic performance
are needed from a partition.
With a unique profile design, the engineered slots create a spring
section, resulting in less acoustic energy being transmitted through
the stud and sound is absorbed within the partition.
Compatibility with the GTEC C Stud system and all GTEC Boards
allows a range of partition performances within identical footprints.
For individual system performances, refer to the System Performance
Tables on pages 22 to 44.
WHERE TO USE:
GTEC Acoustic Stud is an internal partition system for commercial and
domestic applications requiring high acoustic performance levels.

install insulation to achieve a 40RwdB rating.
The narrow stud width and specially configured boards
simplify specification and use the least material to achieve
the demands of Part E.
WHERE TO USE:
GTEC Acoustic Homespan is an internal partition for
new-build domestic applications.

GTEC RESILIENT
BAR PARTITION
SYSTEMS
GTEC Resilient Bar is a versatile component that can be used with
a variety of partitions to provide improved acoustic performance.
GTEC Resilient Bar decouples the plasterboard from the metal frame
to reduce sound transmission with little increase in thickness. It is
fixed across the flanges of GTEC C Stud and GTEC Board to provide a
substrate for the plasterboard away from the metal framing. Refer to
the System Performance Tables on pages 22 to 44 for full details.
See the GTEC Timber Partitions section for details on using the
GTEC Resilient Bar with timber construction.
WHERE TO USE:
GTEC Resilient Bar is used with the GTEC C Stud Partition system
in both domestic and commercial applications.

GTEC® TWIN FRAME PARTITION
®
GTEC TWIN FRAME
PARTITION SYSTEMS
Separating walls and divisions between noisy or noise sensitive
rooms requires very high levels of sound insulation. The GTEC Twin
Frame metal system is a dual layer C Stud Partition used where the
highest fire and acoustic performance is required.
GTEC Twin Frame Partitions are constructed from two metal frames
in parallel, braced together with GTEC Acoustic V Brace and boarded
on the external sides only. Varying cavity size options help optimise
acoustic insulation and provide a service cavity. The GTEC Twin
Frame system is a lightweight, flexible option compared to traditional
masonry separating walls. Refer to the System Performance Tables on
pages 22 to 45 for full performance details.
WHERE TO USE:
GTEC Twin Frame systems are suitable for creating internal dividing
walls in both domestic and commercial applications with increased
performance and / or height requirements.
The highest performing GTEC Twin Frame partitions are commonly
used in cinemas, theatres and schools.
Benefits from all key features as detailed for GTEC C Stud, plus:
FEATURES
BENEFITS
Cavity space between the two frames
Provides high levels of acoustic,
thermal and fire performance
Varying cavity size
Optimisable for obstacles in
the path of the partition
Higher partition heights
Increased height capabilities
Enables use in large commercial spaces
GTEC® TWIN FRAME PARTITION
TIP: GTEC Twin Frame Partitions have been built
in cinemas across the UK as they are ideal for tall,
highly sound insulated partitions.

GTEC TIMBER
PARTITION SYSTEMS
In timber frame construction or where traditional methods dominate,
a timber partition may be the preferred construction method.
GTEC Timber Partitions use timber studs and plates in place of metal
framing with GTEC Board screw fixed to complete the partition. Refer
to the System Performance Tables on pages 47 to 49 for full details.
Separating walls can also be constructed with double layers of GTEC
Board and twin timber frames built in parallel to create a separating
cavity. Insulation is applied in between for further sound reduction.
WHERE TO USE:
GTEC Timber Partitions are used to create internal and separating
partitions within domestic applications.

GTEC® SUSPENDED MF CEILING
®
GTEC SUSPENDED
MF CEILING
SYSTEMS
The GTEC Suspended MF Ceilings are used to create ‘false ceilings’
which house services between the ceiling and soffit. The large voids
created also improve acoustic, fire and thermal performance.
GTEC Suspended MF Ceilings are formed from a series of GTEC
Primary Channels hung from the soffit. Attached to these channels
are GTEC Ceiling Channels, slotted into GTEC Edge Channel to form
the frame. GTEC Board is fixed to the MF frame to complete the
system. Refer to the System Performance Tables on pages 133 to 136
for full details.
WHERE TO USE:
GTEC Suspended MF Ceilings are used for commercial
applications where services are required below the soffit.
For ceilings with enhanced fire and acoustic performance
in commercial and residential applications.
FEATURES
BENEFITS
Variable cavity depth
Optimisable cavity size for service and
insulation requirements
High acoustic, fire and thermal capabilities
Required performance levels are easily achieved
Creates a ‘false ceiling’
Can be used to upgrade or protect
existing structures
Demountable
Easy to renovate
Flat finish
Provides a smooth surface for decorating

GTEC PREGYBEL MF
CEILING SYSTEMS
The GTEC Pregybel MF Ceiling system is used for creating sound
absorbing ceilings to control sound reflection in larger spaces,
creating a more comfortable level of sound and improved audibility.
GTEC Pregybel MF Ceilings combine the easy to install advantages of
the GTEC Suspended MF Ceiling with the sound absorption capability
of GTEC Pregybel Board. Using frame components from the GTEC
Suspended MF system enables flexible design and specification.
GTEC Pregybel board is perforated in a range of patterns for attractive
designs and reduction in the reflective surface of the board to limit
echo or reverberation. Refer to the System Performance Tables on
pages 131 to 132 for full performance details.
WHERE TO USE:
GTEC Pregybel MF ceilings are used in commercial applications
where large, hard-surfaced and uninterrupted spaces would
otherwise suffer from echoing.
GTEC Pregybel MF ceilings are also required for corridors and
stairwells in residential blocks to reduce sound travel through
the building.
FEATURES
BENEFITS
Variable cavity depth
Cavity size can be optimised for service and
insulation requirements
Up to Class B acoustic absorption

GTEC DRYLINER
CEILING SYSTEMS
The GTEC Dryliner Ceiling system is a simple, quick and
cost-effective method for constructing a true, flat ceiling,
even when connecting to uneven joists or concrete soffits.
It also creates a small cavity to accommodate services.
GTEC Dryliner ceilings are made from GTEC Dryliner Brackets
fixed to the soffit or joists, with GTEC Dryliner Channels secured
to them. The channels provide a strong, level substrate for fixing
the plasterboard. GTEC Dryliner Brackets are available for a range
of cavity depths up to 130mm.
Fire rating and acoustic performance can be enhanced by the
selection of appropriate GTEC Boards. Refer to the System
Performance Tables on page 127 for full details.
WHERE TO USE:
GTEC Dryliner Ceilings are used for both domestic and commercial
applications for either new build or renovation projects.
FEATURES
BENEFITS
Improved fire protection for timber joists
Cost effective solution for achieving required
performance
Creates a cavity
Accommodates services without the need to
drill joists
Adjustable brackets
Creates a flat surface even with uneven joists
or soffit
Separation from soffit
Provides improved acoustic performance
No direct connection between board and joists
Reduces risk of plasterboard cracking from
movement of wooden joists

GTEC® ACOUSTIC FLOOR
®
GTEC ACOUSTIC
FLOOR SYSTEMS
Load bearing timber floors separating dwellings or other spaces have
limited sound reduction properties. The GTEC Acoustic Floor, ‘floating
floor’ system improves the acoustic performance of these floors with
minimal additional depth.
The system is installed in a two stage process. GTEC Acoustic Clips
temporarily support GTEC Board mounted on GTEC Metal Angle
between the joists, until the final floorboard layers are fixed to the
plasterboard. The only contact between the board and structure is
through GTEC Resilient Tape. The GTEC Acoustic Floor system also
enables fire protection for existing, hard to renovate, decorative
ceilings by applying GTEC Fire Board from above. Refer to the
System Performance Tables on page 137 for full details.
WHERE TO USE:
GTEC Acoustic Floors are used for domestic renovation and
conversion projects or new build.

GTEC® DIRECT BOND LINING
®
GTEC DIRECT BOND
LINING SYSTEMS
The GTEC Direct Bond Lining system is the simplest option for
single layer drylining of masonry substrates. It provides a clean,
flat and easy to finish surface by bonding GTEC Board to the
masonry substrate. This construction method reduces drying out
time speeding up internal fit-out.
The system uses GTEC Universal Bonding Compound to directly
attach GTEC Plasterboards to the wall and corrects minor surface
irregularities. GTEC Thermal Boards can also be bonded to increase
thermal performance through the wall.
WHERE TO USE:
GTEC Direct Bond Lining systems are used in new build residential
and general renovation projects.
FEATURES
BENEFITS
Few products required
Low installation cost
Limited increase in wall thickness
Minimal effect on room size and achieves the
required finish
Service cavity of 10-25mm can be created
Allows installation of conduits and small services
Suitable for GTEC Thermal Boards
One-fix method of achieving required thermal
performance
Workable bonding compound
Easily achieves air tightness by bonding around
the wall perimeter
Allows adjustment during boarding

GTEC CONTOUR
LINING SYSTEMS
The GTEC Contour Lining system is a simple and fast means
of renovating flat walls which simply need a new, consistently
smooth finish e.g. tiled or plastered walls which have become
scuffed or chipped.
The system uses GTEC Wall Lining Adhesive to directly attach
light and strong GTEC Contour Board to the substrate. It provides
a smooth surface by boarding over existing finishes but will not
correct substrates which are out of plumb.
Once complete, the system provides a smooth and easy to finish
plasterboard surface in the minimum thickness.
WHERE TO USE:
GTEC Contour Board Lining system is suitable for use over
existing wall finishes such as distressed tiled walls.
FEATURES
BENEFITS
8mm total lining thickness

GTEC SHALLOW
WALL LINING
SYSTEMS
The GTEC Shallow Wall Lining system is an alternative to the
GTEC Direct Bond Lining system. It provides a mechanical fix for
boards which are unsuitable for use with GTEC Universal Bonding
Compound. It can also create a fully mechanically fixed option where
the substrate cannot be bonded, such as some concrete walls.
The system uses GTEC Universal Bonding Compound to attach
GTEC Shallow Wall Channels to the substrate providing a fixing
surface for GTEC Boards. When bonded, it can correct minor surface
irregularities through minimal levelling adjustment of the shallow
channel before the dabs have cured. Alternatively, the GTEC Shallow
Wall Channels can be fixed directly into the substrate.
WHERE TO USE:
The GTEC Shallow Wall Lining system is suitable for most project
types and masonry substrates.

GTEC
INDEPENDENT WALL
LINING SYSTEMS
Based on the GTEC C Stud Partition system, the GTEC Independent
Wall Lining system is a fully dry, light frame, drylining system. It is
completely separated from the underlying substrate.
The GTEC Independent Wall Lining system combines GTEC Boards
with GTEC I or C Studs fixed into GTEC U Tracks. The cavity created
behind the boards can be of any depth. This allows for heavy
services, ducting, and insulation.
Once complete, the GTEC Independent Wall Lining system provides
a clean, flat and easy to finish plasterboard surface, offering the
highest technical performances.
WHERE TO USE:
Ideal for commercial projects where deep continuous cavities behind boards
are needed to correct or isolate substrates and accommodate services.
Particularly suited to substrates which may not be suitable for direct fixing,
e.g. metal cladding and other modern methods of construction.
FEATURES
BENEFITS

or finished according to guidance in
Finishing section (p276-291) to achieve
system performances.
GTEC Pregybel Board to be sealed and
painted with rollers to prevent blocking tissue
backing and reducing absorption capability.
GTEC Finish materials appropriate to board
type to be used.
PLAN
GTEC Pregybel boards to be arranged to
achieve desired board pattern. GTEC Pregybel
Boards and GTEC Boards may be mixed
for decorative effect however acoustic
absorption only occurs where board, void and
insulation match the system performance.
GTEC Pregybel boards are recommended
for use above pedestrian height
unless otherwise protected.
SYSTEM CONTINUITY
Only areas with full system continuity will
achieve rated performances.
Bead of GTEC Intumescent Acoustic
Sealant to be applied to perimeter of all
runs and in all other locations specified in
Construction Detail Drawings to prevent
dust accumulation.

GTEC Acoustic Panels are suitable for fixing
to most, level, stable and secure substrates
and should be fixed with appropriate fixings
capable of supporting the load of the panel.
SECTION
Board and insulation configuration to be
selected according to acoustic absorption
and pattern required, see performance tables
p180-191.
Box to be positioned above height of
pedestrian movement to prevent crowd
loading, GTEC Acoustic Panels are selfsupporting only.

FIRE PROTECTION PERFORMANCE NOTES
Performance values are for imperforate, jointed systems using Siniat GTEC components (metal studs and tracks, boards,
metal accessories, screws and finishing systems) and specified insulation quilt material (type, thickness and density)
and installed to Siniat specification and installation guides.
Maximum heights depend on deflection criteria and applied air pressure.

GTEC SHAFTWALL
SYSTEMS
The GTEC Shaftwall Fire Protection system protects shafts
and voids in multi-storey buildings with a rapid installation
system preventing continuous routes for the spread of fire.
The system uses a non-symmetrical board assembly for full
installation from one side of the shaft, allowing construction in
tight spaces. The frame features friction fit channels to receive
GTEC Fire Core Board and a fixing flange for the installation
of GTEC Fire, Megadeco or Universal Boards ready to finish on
the room side. The shaft side can also be decoratively finished
using GTEC Shaftwall Stairwell systems, this is commonly used
in stairwells.
GTEC Shaftwall Fire Protection can also be used horizontally to
protect the underside of ductwork or provide a ‘lid’ to a shaft.
In horizontal applications, further boards may be needed to
achieve fire performances. Refer to the System Performance
Tables on pages 244 to 249 for full details.
WHERE TO USE:
GTEC Shaftwall Systems are used to protect voids in commercial or
public multi-storey buildings and is suitable for most construction types.

GTEC ENCASEMENT
SYSTEMS
The GTEC Encasement Fire Protection system provides high levels of
fire resistance to structural I-section columns and beams, delaying the
loss of strength in steel which occurs at temperatures over 550°C.
The system uses push-fit GTEC CB Clips to secure GTEC Edge Channel
to the steel. GTEC Fire Core Boards, Fire Boards, and other high
performance boards as detailed in the performance tables, are fixed
to the edge channel to protect columns and beams. Excellent fire
performance is achieved by holding the boards off the columns on a
strong metal frame.
WHERE TO USE:
The system is used in commercial multi-storey construction to ensure
structural safety during fire. The range of impact resistant boards
compatible with the system enables use in high traffic areas.

GTEC® TAPING AND JOINTING
®
GTEC TAPING
AND JOINTING
GTEC drywall systems require taping and jointing to complete
the wall surface, reinforce joints to prevent cracking, and
ensure fire and sound performances are achieved.
GTEC Taping and Jointing products use limited combustibility,
gypsum and limestone based compounds which secure the
fire rating of the system. These are reinforced with paper tape
or corner beads to create a smooth, durable surface, ready for
decoration. Two and three stage processes are available using
the correct GTEC Finish products to provide options on site and
different setting times.
Water resistant compounds and finishing accessories are
available for GTEC Aqua Board. The GTEC Deco compound range
complements the use of GTEC Megadeco for direct decoration.
WHERE TO USE:
Taping and jointing are suitable for large surface areas
where speed and ease of application can greatly reduce
installation cost and drying time.
FEATURES
BENEFITS
Applied to low surface areas
Quicker than a full plaster skim with less drying

GTEC® TAPING AND JOINTING
SYSTEM GUIDANCE
COMPOUND SELECTION
Joint compound selection is largely a matter
of site preference, depending on weather
conditions, time and equipment. GTEC
Compounds can be combined in numerous
permutations each offering a high quality
surface finish. However, GTEC Aqua Board and
GTEC Megadeco require specific compounds to
suit their unique facers.
Taping and jointing is conducted in three
main stages: Bedding; Second Coat; and
Finishing Coat.
TWO STAGE PROCESS
1
THREE STAGE PROCESS
BEDDING
Tape or bead is bedded into the
compound and taper filled out
SECOND COAT
The taper is re-filled with
compound where required

FINISHING COAT

Final compound layer is applied
and sanded for a smooth finish
3
COMPOUND TYPES
All compounds are suitable for Bedding and
Second Coat, however, setting and hybrid
compounds reduce overall time required.
Setting and hybrid compounds must not be
used over air-drying compounds.
Only air-drying or hybrid compounds are
suitable for the final finishing coat.
Air-drying and hybrid compounds are low
shrinkage. Where low shrinkage compounds
have been used in Bedding layer the Second
Coat may not be required.
The drying time of air-drying compounds
is dependent on climatic conditions and
layer thickness. Drying takes approximately
24 hours but may be extended by adverse
conditions.

INTRODUCTION
SINIAT FIRSTS:
Sustainability has long been a core value at
Siniat and is now top of the agenda for everyone
in the construction supply chain. We remain
committed to sustainable development and
construction in both our business approach and
in meeting the needs of the built environment.
As a leading supplier of construction
products, Siniat has a huge responsibility.
Building materials meet basic human
needs for the buildings that are part of
everyday life. With economic growth and
social development increasing demand
we have to balance the human benefits
of our products with the availability of
finite and non-renewable resources.
2004: The first plasterboard
manufacturer in the UK to
achieve ISO 9001 and ISO
14001 certification for all
activities – these international standards provide
the framework for our conservation of natural
resources. They ensure continuous improvement
in quality and service, as well as emission
reductions and innovative solutions for ever
more sustainable buildings.
Therefore, at Siniat, we focus on environmental
sustainability and leaving the lightest possible
trace on the earth while enabling the social and
economic sustainability of our operations.
2011: The first plasterboard
manufacturer in the UK to
achieve BES6001 certification,
the industry sustainability
standard for the responsible sourcing of
construction products. This independent
assessment certifies environmental stewardship
and social and economic sustainability within
our operations and supply chain.
SUSTAINABILITY
OUR SUSTAINABILITY POLICY:
A LIFE CYCLE APPROACH
GYPSUM WASTE RECYCLING
To meet your client’s sustainability targets,
Siniat takes a life cycle approach to minimising
the environmental impacts of manufacturing
and supply operations.
All of our plant and supply chain activities
translate into embodied impacts (such as
carbon, water and recycled content) within your
construction project. Therefore, we intervene at
every life cycle stage to reduce these through
material and energy resource minimisation,
efficiency and recycling.
AND IT’S NOT JUST ABOUT THE
ENVIRONMENT…
As part of our product stewardship, we
provide for the communities of people
supplying our materials; manufacturing
our products; living near to our plants; or
installing our products and systems on site.
We have adopted the United Nations Global
Compact within our Responsible Sourcing
Policy and expect suppliers to do the same.
MINIMISING WASTE
Whilst all drywall projects generate waste from
off-cuts, steps can be taken to minimise this.
Our project teams can help you reduce waste
through selecting appropriate products and
systems, and efficient design detailing. Where
necessary, we can supply boards and metal studs
in non-standard lengths to reduce wastage on
site. Reducing damage to boards and pallets
with good site storage and transport practices
can also make a big contribution.
An outstanding sustainability credential
of plasterboard is that it can be recycled
into new board products with no loss
in quality. Siniat has been recycling
plasterboard process waste for many years,
becoming the first to eliminate plasterboard
manufacturing waste to landfill in 2005.
We’ve expanded our site waste recycling
and recovery activities since 2000 and are
now the leading recycler of plasterboard
waste in the UK. Our post-consumer
waste recycling rate exceeded the sector
average in each of the years 2009-2011.
European and UK regulations now require
all gypsum waste to be segregated at source.
While it remains legal to landfill gypsum waste
in dedicated facilities our GTEC Wasteline Direct
service makes this easy to avoid, recycling many
thousands of tonnes of waste every year.
Offered to merchants, distributors and
contractors our GTEC Wasteline Direct service
can take care of all your plasterboard waste
management needs. Siniat partners with
specialist providers, to offer cost-competitive
collections on a national basis.
Monthly reports of quantities removed are
provided by GTEC Wasteline Direct. Siniat will
endeavour to recycle the waste back into new
plasterboard wherever viable. Where this is
not possible, we direct the recovered gypsum
to other favourable uses approved by the
Environment Agency. GTEC Wasteline Direct
will not landfill any clean plasterboard waste
recovered by the scheme.
An up-to-date list of the GTEC products accepted
by the scheme is available on our website where
you can also request a service cost quotation.

1. All our supply quarries have a biodiversity rehabilitation
plan with state-of-the-art replanting. Delivery by bulk
shipping is 20 times more carbon efficient than road
transport.
2. Flue Gas Desulphurisation (FGD) systems used in
power stations eliminate sulphur dioxide emissions
and produce high purity gypsum as a by-product.
We operate the only integrated FGD gypsum
plasterboard manufacturing site in the UK,
eliminating delivery transport.
3. The plasterboard liners we use comprise 100%
recycled paper, principally from post-consumer
packaging.
4. Our manufacturing process has very few emissions
as all process water and waste is recycled internally.
Zero waste goes to landfill. Our £1.6 million
investments in energy efficiency saved over
40,000 tonnes of carbon dioxide by 2010.
7. Board Recycling Plant
5. Packaging is the second largest source of waste
in construction. Against a national target of 20%
Siniat reduced packaging by over 50% following
investments of over £1 million. The bearers
used for board packaging are from certified
and sustainable sources.
6. We pioneered the use of fuel-saving ‘teardrop’ trailers
to limit the impacts of product delivery. Coupled
with LPG conversion the carbon footprint of our
distribution activities has been reduced by 10%.
7. Almost all GTEC Plasterboards are fully recyclable into
new products. The gypsum and paper are separated,
with both suitable for closed-loop recycling.
Our GTEC Wasteline Direct service offers a
plasterboard recovery and recycling service. In each
of the years 2009-2011, Siniat reported the highest
post-consumer board recycling rate in the industry.

SUSTAINABILITY
THE CODE FOR SUSTAINABLE HOMES
The Code for Sustainable Homes applies in
England and Wales to drive a step-change
in sustainable home building practice.
GTEC Products, Systems and Services help gain
credits, pushing projects up the rating scale.
The Code measures the sustainability of the
home in nine design categories, and awards
a rating of one to six stars, depending on
achievement against the Code benchmarks.
For all Code levels, there are minimum
requirements for Energy and CO2 emissions
and Water consumption.
building sustainability. As with the Code for
Sustainable Homes, the GTEC range can make
a significant contribution to higher ratings.
BREEAM involves nine key areas of project
design. Credits are awarded in each of the
design areas and the overall score is calculated
from a weighted scorecard of the section
credits. The final score is then rated as Pass,
Good, Very Good, Excellent or Outstanding.
Education and Healthcare buildings must
meet certain minimum ratings, and other
ratings criteria may apply to building projects
as a condition of planning approval.
REFURBISHMENT PROJECTS
Credits are awarded in each of the design
areas, and the overall score is calculated from
a weighted scorecard of the section credits.
The assignment of credits within the Code’s
Energy section has been recently updated
to reflect the importance of installing a
thermally efficient building fabric as the
most cost-effective approach. This hierarchy,
known as the ‘fabric first’ approach, is
now reflected in the Code with credits for
Fabric Energy Efficiency performance.
Following much regulation in the new build
sector, the UK Low Carbon Construction
Action Plan is now focusing on improving the
thermal performance of existing buildings.
The Government is due to launch its Green
Deal package in Autumn 2012 where building
improvements will be funded by energy savings
in consumer energy bills. Siniat offers several
products and systems suitable for Green Deal
measures: please contact Technical Enquiryline
for further details.
BUILDING RESEARCH ESTABLISHMENT
ENVIRONMENTAL ASSESSMENT
METHOD (BREEAM)
Alongside the Green Deal, BRE have launched
a new BREEAM scheme in 2012 for the
sustainability assessment of domestic
refurbishment projects. Building on our
experience gained piloting the scheme,
Siniat will be pleased to support you with
any project requirements.
BREEAM is the most widely used environmental
assessment method for buildings in the UK. It
provides a consistent and robust means of rating
GTEC SYSTEMS IN THE CODE FOR SUSTAINABLE HOMES AND BREEAM:
The range of high performance GTEC Thermal Boards provide for space-efficient insulation.
The Global Warming Potential (GWP) of all these insulated boards is below 5, accessing additional credits.
GTEC systems achieve the high sound insulation values necessary to gain the credits for exceeding Building
Regulation requirements.
In the Materials Section, the excellent BRE Green Guide ratings of GTEC Systems and our BES6001 certification for
Responsible Sourcing both access credits.
Our plasterboard waste recovery service, GTEC Wasteline Direct, can support your site waste management needs
and is also eligible for credits.
Durability credits are available where Severe Duty partitions are used in corridors and public areas. (BREEAM only).
The zero release of VOC’s (volatile organic compounds) from GTEC boards contributes to Indoor Air Quality.
Specification of GTEC Megadeco can also minimise the release of VOC’s during the build. (BREEAM only).
Siniat supports contractors during construction in areas relevant to Project Management credits,
e.g. by minimising construction site impacts. Drawing on their vast experience with all building types,
our projects team will support achievement of the best possible BREEAM or Code rating.
HEALTH AND SAFETY
HEALTH AND
SAFETY
Siniat has a deep commitment to zero harm in our industrial activity. We follow
an active policy for continuous improvement in reducing incidents and protecting
our employees’ health. In our supply chain we require similar exacting standards
from our suppliers.
To protect the health of construction workers and building occupants, we minimise
the use of any hazardous materials and will avoid using substances of high concern.
Our development programme brings innovative products to market which reduce
health and safety risks on site and throughout the life of the building.
CE MARKING
All Siniat GTEC products are CE marked in accordance with
the EU Construction Products Directive and the relevant
harmonised European standard. This ensures that the
essential requirements relevant to safety in use (e.g. reaction
to fire or tensile strength) are type tested in accredited
laboratories. Our ISO9001 quality management processes
ensure continuing compliance. From July 2013, products
will be CE Marked with reference to the EU Construction
Products Regulation 2011/305/EC.
MANUAL HANDLING
CHEMICAL SUBSTANCES AND
PRODUCT SAFETY
Siniat ensures that all materials in its supply chain are
registered under REACH* where necessary. We have also
registered directly as a producer of calcium sulphate, the
main raw material used in our products; evidence and our
REACH registration number is available on request.
Siniat board products do not contain or emit volatile organic
compounds (VOCs) and our pre-finished GTEC Megadeco
Board removes the need for on-site sealing, further enhancing
the indoor air quality of your projects.
In collaboration with the Health & Safety Executive, Siniat
has introduced weight labelling on all UK-produced board
products. This information helps users to reduce injuries
through risk assessment.
The sealing products in the Siniat GTEC range have an
aqueous base and contain VOCs at the lowest classification
level under the current regulations (<30g/litre).
Example of product marking:
All GTEC products are classified as non-hazardous according
to the CHIP4 (UK) and CLP (EU) Regulations and are stable
and non-reactive with other building materials.
The sawing of plasterboard and the sanding of finishing
compounds may generate dust. Whilst there are no known
toxicological effects for gypsum products, Occupational
Exposure Limits (OEL) exist for mineral dusts and the use
of personal protective equipment is recommended.
