ROCKWOOL PWCB Party Wall Cavity Barrier has been created to provide excellent levels of fire stopping for timber frame and masonry properties. They have been designed to meet building regulation requirements for fire resistance in concealed wall cavities, having been tested and assessed for up to 60 minutes’ integrity and insulation, exceeding the minimum requirements.

This cavity wall insulation product has been created from non-combustible stone wool and wrapped within a resilient polythene sleeve which acts to provide weather protection during installation. An all in one solution, the ROCKWOOL PWCB cavity barrier also achieves the trilogy of requirements for fire safety, acoustic flanking and thermal bypass in one single product whilst providing effective perimeter edge sealing, reducing the leaking of air and associated heat loss.
