Where to use it

Gutex Thermoflex mats can be used in between rafters, joists and studs in walls, roofs and suspended timber floors. It can also be used as loft insulation installed between ceiling joists in a loft space. Thermoflex is suitable for internal or external timber frame stud walls, pitched roofs and flat roofs.

What it does

Gutex Thermoflex provides excellent thermal performance in the winter months and reduces the potential for summer overheating.

It is highly breathable (moisture vapour diffusion open), which means that it can assist in regulating internal humidity and help prevent interstitial condensation and mould growth within the fabric of the building. Control of condensation and eradication of mould make an excellent contribution to the improvement in indoor air quality.

Thermoflex insulation mats can be used in conjunction with breathable external structural boards (for example Elka Strong Board) and with Pro Clima Intello Plus. This provides excellent breathability in winter and allows for moisture driven back into the building by summer sun, to dry harmlessly.

Why we love it

Gutex Thermoflex is ideal for insulating new buildings or thermally upgrading existing buildings. It is easy to cut and easy to install by squeezing it in between timbers. Friction and the spring of Thermoflex keep the insulation securely in place, making it ideal for DIY or professional installation. It is a natural product that is safe to handle, does not irritate skin. 

Thermoflex is made from recycled wood chips that were produced as waste from locally manufactured products for the timber frame industry. The wood chips were originally trees grown in sustainably managed forests. As the carbon emitted during manufacture is less than the carbon absorbed by the trees and stored in the wood, Thermoflex actively contributes towards reducing global CO2.
