Open state fire barrier to prevent the spread of fire for up to 180 minutes, for cavity widths up to 500 mm.
Designed to reinstate the horizontal fire resistance performance of facades which have been designed to maintain a continuous air flow around the building and must accommodate a continuous air gap at the cavity barrier, allowing moisture to dissipate under normal circumstances, but reacting in the event of fire to rapidly close off the air gap to help prevent the spread of fire and hot smoke.
PFC Corofil Open State Barriers are designed to close off 44 mm air gaps. The intumescent strip will expand on heating to close off the air gap between the barrier and inner surface of the facade. Galvanized steel brackets are supplied as standard, stainless steel brackets can be ordered separately if required. The fire resistance performance varies depending on which barrier is required to suit the application and build up of the substrates. PFC Corofil Open State Barrier range is compliant to current market requirements and has been tested to the general principles of EN 1363-1 and in accordance with ASFP Technical Guidance Document 19 (TGD 19).
