Glidevale’s Protect TF200 Thermo combines the benefits of their TF200 timber frame vapour permeable membrane with enhanced thermal performance.
This is achieved using a thermally bonded integral highly reflective aluminium layer, helping achieve the requirements of Approved Document L. In fact, thermal performance can be improved by up to 170%
Used conventionally with traditional mineral wool insulation, Protect TF200 Thermo improves the U value from 0.28W/m2K to 0.25 W/m2K. When used in conjunction with Glidevale’s Protect VC Foil reflective vapour control layer, performance is further enhanced to 0.22W/m2K* and has the added benefit of incorporating a service cavity on the warm side of the insulation.
In an unventilated airspace larger than 20mm with Protect TF200 Thermo facing into the airspace, an R-value of 0.49W/m2K is achieved, giving a 170+% improvement on thermal performance over a conventional airspace.
As well as complementing the wall’s thermal performance, TF200 Thermo provides a water vapour resistance of 0.5MNs/g, achieving the requirements recommended by TRADA and the NHBC. It also gives a second line of defence against condensation build-up for the life of the building.
UV and heat stabilised, the membrane’s reflective surface is corrosion and damage resistant. Protect TF200 Thermo has high burst, tensile and nail tear strengths, minimising damage in transport and during installation and on-site. It is available in 2.7 x 100m and 3.0 x 100m rolls.
“Building Regulations increasingly demand for us to construct airtight, thermally efficient buildings. The key is keeping the warm inside and the moisture out. Protect TF200 Thermo achieves both in one easy to use membrane,” said Glidevale senior product manager Bruce Newman.
