Rockwool PWCB Cavity Barriers work to improve a building’s safety by preventing the spread of fire within concealed voids. By specifying and installing the TCB Cavity Barrier or PWCB Cavity Barrier, they provide essential protection whilst also helping to minimise air leakage and heat loss between the external cavity and the separating party wall.

Installation guidelines

ROCKWOOL TCB & PWCB Cavity barriers can be used in both vertical and horizontal applications, providing an effective fire, acoustic and thermal barrier within external wall cavities and separating party walls.
All ROCKWOOL Cavity barriers are 1200mm long and are designed to be compression fitted within the cavity (min 10mm15mm compression). The barriers do not rely on the polythene flanges to hold them in place in the event of a fire. It is essential that the correct cavity barrier size is specified to suit the as-built cavity width. TCB & PWCB cavity barriers are available in a range of thicknesses to suit cavity widths (refer to the tables at the end of the data sheet for more information).
