Envirograf Rainscreen Fast Fix Cavity Barriers allow airflow through rainscreens and cladding systems, sealing up in the event of fire to protect buildings from spreading flames and smoke. Both sides of the rock-fibre barrier are coated with intumescent material, whilst the airflow side is fitted with an intumescent strip that expands to cover the airflow gap, up to the external wall.

The cavity barriers are 1220mm in length and are supplied with fitting brackets, 3 per length.

Application

Suitable for both horizontal and vertical applications. The fixing brackets supplied need to be mechanically fixed to the substrate using non-combustible fixings. Fit the brackets at 500mm centres then push the lengths of barrier onto the brackets ensuring they are centred in the middle of the barrier and that the barrier is pushed fully back against the substrate. When fitting the barriers ensure that the brown-faced intumescent strip is facing forward. Note: the intumescent strip is colour-coded with white pins for a 25mm airflow gap and red pins for a 40mm airflow gap.
