Carbon dioxide, contained in a vessel attached to the cladding panel, is then released into the cavity, thus restricting the supply of oxygen to the fire. FB Cavity Barrier consists of stainless steel (AISI 3044) woven mesh and an intumescent material that expands when exposed to heat. The WB Cavity Barrier is a thin flexible foil faced intumescent strip which is fixed in a horizontal position in a brick/block cavity which is held in place with mortar. In the event of exposure to fire, this expands and fully seals the designed ventilation gap formed at the time of installation between the barrier and the rear of the cladding, in compliance with CWCT and NHBC guidance for air gaps up to 50mm. Effective ventilation area Vented cladding can be designed in many ways and with different types of material. They are fitted within the cavity of a building at each floor horizontally and party wall in a verticle position. Adjoining cavity barriers should be tightly butt jointed.
