Cavity fire barrier designed to be compression fitted within a timber frame cavity. In vertical applications, both flanges are fixed; in horizontal applications, only the top flange should be fixed. The flanges are fixed to the frame using clout nails at 150 mm centres.

The polythene encapsulation offers on-site weather protection but can be cut away without affecting the barrier’s performance.

It restricts the spread of smoke and flames within timber frame cavity walls, as well as minimizing the effect of flanking noise pollution at wall junctions. It is manufactured from low-resin, non-combustible rock fibre mineral wool insulation and is sleeved in polythene for on-site protection.

This product restricts the spread of smoke and flames within the cavity of timber frame walls, while also minimizing the effect of flanking noise pollution.
