TLX Gold Thinsulex Multifoi Insulated Breather Membrane - 1.2m x 10m

The TLX Gold Thinsulex Multifoil Insulated Breather Membrane 1.2m x 10m is a high performance roofing solution that combines insulation and membrane technology in one advanced product. Designed for modern pitched roof applications, this multifoil insulation roll delivers improved thermal efficiency while helping manage moisture within the roof structure.

Manufactured using a layered multifoil construction, TLX Gold reflects radiant heat back into the building while reducing heat loss through the roof. At the same time, it allows controlled moisture movement, helping to minimise condensation risk without the need for additional ventilation layers or major roof build up changes. This makes it a practical option where maintaining roof height is important, such as in loft conversions, extensions, and refurbishment projects.

With a thickness of approximately 33mm, this insulated breather membrane offers a slim yet effective solution for improving energy performance. It can be installed above the rafters, helping to create a more efficient thermal envelope while simplifying installation compared to traditional multi layer insulation systems. Its lightweight and flexible design makes it easy to handle on site, reducing labour time and improving installation speed.

TLX Gold is widely used across a range of applications including new build roofs, barn conversions, timber frame structures, and both private and social housing projects. It is also suitable for more demanding environments such as public and heritage buildings where performance and reliability are essential.

Backed by BBA certification, European technical approval, and LABC endorsement, this multifoil insulation membrane meets recognised UK building standards and offers long term durability. With a thermal resistance of 0.85 m²K/W, it provides a reliable contribution towards meeting current building regulation requirements when used as part of a complete insulation system.
