Envirograf Timber Frame Cavity Barrier Range

Advantages:

Both barrier ranges will provide a minimum of 2 hours protection.

CV strip barriers are ideal for modular buildings where space is limited, due to their small profile.

FB/TS is a more robust barrier that is ideal for load-bearing party floors and walls.

Easy to install with adhesive strip, but can be fixed down with screws or nails to provide additional fixing.
