PWCB Cavity Barrier

Cavity Barriers.

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.
