    Rockwool TCB Cavity Barrier (22C)

    Product Description:

    ROCKWOOL® TCB Cavity Barrier is a fire safety solution for timber cavity constructions including floating floors and separating walls. The product provides a ½ hour cavity barrier or 1 hour dependent upon cavity size. The product consists of a 1200mm strip of ROCKWOOL® inserted into a red polyethylene sleeve incorporating two flanges designed for fixing. (Non-standard sizes have a single flange only.) Cavity widths from 50mm up to 140mm can be accommodated; the use of the correct size for the actual cavity is essential for compression fit.


    • Simple to install and fix
    • Held in place by compression
    • Weather protection during fitting
    • Water repellent
    • Maintenance free
    • Fire tested

    ROCKWOOL® TCB Cavity Barrier provides fire stopping to prevent the spread of fire through walls, floors and cavities.
