FR Membrane Barrier

The Protecta® FR Membrane Barrier is a tested system providing up to 60 minutes fire resistance in linear voids between roofing moisture membranes and roof tiles. Installed alongside fire-classified partition walls in loft spaces, it prevents fire from spreading between compartments—helping to protect lives, animals, and property by containing the fire at its source.

Compatible with:

- Flexible walls (min. 95 mm, timber or steel studs with 12.5 mm board each side)
- Rigid walls (min. 95 mm concrete or masonry)
- Protecta FR Board Partition Walls (ETA 23/0496)

The barrier is fitted on both sides of the partition wall and incorporates graphite strips that expand under heat, closing the gap between the roof membrane and tiles. Without this protection, fire can bypass compartment walls through the open void above.
