Enquire About This Product

FIREZERO/R50/VOID is designed to go between the external rain screen cladding and the internal wall structure to create a fire break horizontally, normally at the floor beam/slab level. The product can also be used in the vertical plain at separating wall junctions to complete fire compartments where an air gap is require the brackets should be fixed alternatively to prevent slippage. Generally an air gap is not needed vertically as an acoustic/fire seal is required to prevent the flanking transmission of sound under building regulations therefore a FIREZERO/RSV fire stop can be used . This works under compression filling the vertical void creating an economical solution. Although fixed by compression the fixings provide must be used as per the supplied fixing instructions. FIREZERO Passive fire seals will achieve 30 to 120 minutes when fitted correctly between structures which are equally rated.
