Rockwool TCB Cavity Barrier 1200 x 65 x 65mm 318157

This cavity barrier is designed for use in timber frame construction, fitting into wall cavities to help manage fire risk and reduce heat transfer. Supplied in a 1200mm length with a 65 x 65mm profile, it is straightforward to position within concealed spaces.

On site, it is commonly used at wall junctions and perimeter zones to divide cavities, assisting with compartmentalisation. The rigid, stone wool construction enables consistent installation across both vertical and horizontal junctions in partition and party wall assemblies.
