TLX Silver is easily and quickly installed, space saving, flexible reflective insulation with combined breather membrane.
This is the brighter way to insulate, as it delivers an air barrier; allows water vapour to pass through, and provides all the benefits of multi-foil insulation
TLX Gold is an insulating membrane that controls water vapour and air movement, enabling a building to ‘breathe’ whilst delivering a comfortable and energy efficient environment.
Described as a ‘space blanket for buildings’, by the Carbon Trust, TLX Gold reflects heat back into the building to conserve maximum energy and is ideal for use in traditionally hard to insulate buildings. It has successfully been put to the test in the refurbishment of a number of historic buildings as well as several public sector, retro-fit social housing, property conversion and new build projects.
The manufacturer has independent test certificates by BBA (British Board of Agrément); BTTG Fire Technology Services and High Performance Materials and the University of Salford’s Thermal Measurement Laboratory. TLX Gold is also currently seeking European Technical Approval (ETA).
TLX Gold from Web Dynamics, the energy and moisture management specialist, has been commended by the Carbon Trust for its contribution to the development of technology which offers major potential to reduce carbon emissions.
The Carbon Trust, with more than 250 submissions from across the UK, nominated Web Dynamics as a finalist in its 2009 Innovation Awards. TLX Gold came up against fierce competition at the Awards and was able to demonstrate the benefits of its TLX Gold combined multi-foil and breather membrane, and show how technology can help reduce emissions from buildings.

TLX Gold Installation Examples with estimated U-Values
General Instructions
Protective clothing is not required when handling TLX
Gold
TLX Gold must be installed Gold side facing in.
Bare electrical wiring must not be allowed in contact
with TLX Gold. PVC coated electrical wiring to normal
domestic items such as light fittings may come into
contact with TLX Gold.
If electrical cables are surrounded by insulation they may
need to be de-rated and guidance should be sought
from a qualified electrician.
Installation without Counter-Battening
The left hand side of TLX Gold is fixed in place with
staples or nails of at least 14mm, and the TLX Gold
rolled across the rafters leaving a 10mm drape between
each rafter space. Staple the TLX Gold every few rafter spaces to hold it in place. The product is installed
horizontally, either from ridge to eaves or from eaves to
ridge.
Each layer of TLX Gold must butt-join the previous layer,
with the membrane overlap running onto the lower
layer, thus ensuring that any water runs down the roof
slope without penetrating between layers. The drape
should be consistent for each layer of TLX Gold.
A 10mm channel should run above the TLX Gold, up the
centre of each rafter space, to allow water to run down
and for air movement. If a clear channel is not formed,
10mm spacers underneath the tiling battens may be
fitted.
The membrane overlap on the bottom layer of TLX Gold
should extend onto a suitable eaves carrier. Additional
breather membrane may be used to cover the gaps
between TLX Gold and the eaves carrier if required.
Vertical overlaps should be a minimum of 50mm.
TLX Gold is permanently held in place by tiling battens
and tiles are fitted. The tiling battens should hold the
layers of TLX Gold in close contact, if there is any doubt
then the overlap may be taped in place with a suitable
double sided tape.
Installation with Counter-Battening
TLX Gold is rolled taut across the rafters in horizontal
layers parallel to the eaves. The product can be installed
either from ridge to eaves or from eaves to ridge.
The membrane overlap on the lowest layer of TLX Gold
should extend onto a suitable eaves carrier. Additional
breather membrane may be used to cover the gaps
between TLX Gold and the eaves carrier if required.
As TLX Gold is unrolled across the rafters it is fixed in
place with nails or staples of at least 14mm length. The
next layer of TLX Gold must butt-join the previous layer,
with the membrane overlap running onto the lower
layer, thus ensuring that any water runs down the roof
slope without penetrating between layers. Vertical
overlaps should be a minimum of 50mm.
TLX Gold is permanently held in place with 25mm deep
counter battens, then tiling battens and tiles are fitted.
The counter battens should hold the layers of TLX Gold
in close contact, if there is any doubt then the overlap
may be taped with a suitable double or single sided
tape.
Cutting
TLX Gold can be cut using a sharp knife with the TLX
Gold resting on a board, with sharp scissors, a special
cutter or a hot knife.
Pieces which have been cut should be stapled and
battened as soon as possible, and should not be left
unsecured overnight.
Small pieces (such as around Velux windows or in
dormer cheeks) should be taped in place, stapled and
battened immediately.
Any small tears or holes should be repaired with tape.
Larger holes in the top layer of TLX Gold should be
patched with a piece of breathable underlay.
Taping
Where TLX Gold requires taping, it is recommended that
Indasol 666 38mm double sided tape is used.
Henkel All Purpose Duck tape may be used.
Air layers
Unventilated air layers form an important part of the
TLX Gold system. If the air spaces are omitted, whilst
there is no danger of condensation, the overall thermal
performance of the structure will decrease, and the U-value will be higher. Additional insulation may be
needed to achieve the desired U-value for the roof.
Additional Insulation
Install additional insulation according to the
manufacturer’s instructions.
Provide for air gaps between TLX Gold and additional
insulation as required.
Storage
TLX Gold rolls must be stored on a dry flat surface,
protected from the weather and direct sunlight.
Make sure when installing TLX Gold that it does not
come into contact with heat sources above 80°C.
Vapour Control and Ventilation
A vapour control layer is not required for any of the
recommended solutions, using breathable products
prevents trapping of water vapour.
A well-sealed ceiling is essential to prevent large
amounts of water vapour from entering the roof space
through air movement.
Ventilation of the space between the TLX Gold and the
outer roof covering is not required for air-open
coverings such as clay or concrete tiles and rough natural
slates. Smooth slates and sealed roof coverings such as
metal roofs require additional ventilation of this space.
If in any doubt about possible harmful condensation,
contact Web Dynamics Ltd for guidance.
