TCB’s and PWCB Cavity Barriers

Fire Protection for timber frame & masonry cavity walls.

Preventing fire spreading through concealed voids is essential for improving safety and property protection. One of the best ways to achieve this is to correctly specify and install cavity barriers.

Rockwool Cavity Barriers have been specifically developed to exceed minimum building regulation requirements for fire resistance in concealed wall cavities. They have been tested and assessed for up to 60 minutes fire resistance (Integrity and Insulation).
