Leading manufacturer Glidevale Protect has launched Protect FrameSafe FR - a new Class A2-s1, d0 flame retardant external wall breather membrane offering fire protection across low, medium and high-rise buildings.

Featuring an intricately woven glass fibre fabric with a uniquely developed waterproof and fire-resistant coating, Protect FrameSafe FR is a high-performance breather wall membrane for use on the external side of the frame to integrate with façade wall structures. It is designed to exceed Building Regulations Approved Document Part B.

Protect FrameSafe FR has been independently fire tested by an external laboratory both free hanging as well as part of a system in an end-use application, fixed over A1 and A2 substrates using Protect FR tape, which is also available to seal laps. It is fully compliant with the test methods contained within EN 13501-1, making it the perfect solution for higher-risk buildings as defined in the 2022 Building Safety Act, including student accommodation, schools, hospitals, offices and care homes as well as being suitable for many developments in London where there is a combustible material ban on external walls of buildings. In addition, the product can be used for housing developments where the property wall has a minimum separation distance of 1m to the relevant boundary.

Suitable for use on a wide range of residential and commercial developments, Protect FrameSafe FR provides strong UV stability and up to six months of exposure before being covered. It is ideal for modular and offsite construction projects, for use on both steel and timber framed buildings as well as on high-rise buildings with full rainscreen cladding systems.

Produced in the UK, Protect FrameSafe FR is both UKCA and CE marked with full independent fire test certification. For further product details please visit or for all recommended mechanical fixings and full specification guidance contact Glidevale Protect’s technical team at
