Glidevale Protect unveils its new fire rated internal membrane - Protect FrameFoil FR

Leading UK producer Glidevale Protect has launched Protect FrameFoil FR, a new Class A2 fire rated, reflective air and vapour control layer (AVCL) and separate FR sealing tape designed to improve the thermal performance and airtightness of internal walls, ceilings, and floors. The new solution has been developed to work alongside Glidevale Protect’s established A2 rated FrameSafe FR external breather wall membranes to offer a complete system both inside and out for low, medium and high rise projects. This offers added protection for structures, particularly in high risk, multi occupancy builds over 11m in height, specifically those covered by the Building Safety Act. The product is ideal for modular and offsite construction as well as traditional builds in both the residential and commercial sectors.

Designed for use internally across steel, masonry, and timber-framed structures, Protect FrameFoil FR is best installed as a system where the membrane laps are sealed with new Protect FR Foil tape to deliver a fully fire rated, airtight and vapour control solution. This membrane and tape system has been independently fire tested both with the membrane free hanging and as a system application fixed over A1 and A2 substrates, achieving a Class A2-s1, d0 reaction to fire rating. Using the combination of Glidevale Protect’s fire rated wall membranes exceeds the requirements set down in Building Regulations Approved Document B in the UK and Building Regulations Technical Guidance Document B in Ireland.

Featuring a woven, glass fibre construction with an aluminium foil surface, FrameFoil FR enhances thermal efficiency, achieving an aged thermal resistance (R-value) of 0.64 m²K/W when used facing into a still air cavity, contributing to overall energy performance.
