Cavity Barriers are mostly used to prevent fire and smoke between cavities such as in blockwork, cladding, curtain walling and above ceilings. The primary function is to maintain continuity of fire resistance by sealing the cavity gap between the compartment floors or walls and the external curtain wall both horizontally and vertically. The materials comprise a one-piece product having a pre-compressed non-combustible rockfibre core. The products also have integral aluminium foil facings to provide a Class O rating and excellent resistance to smoke.
