Cavity fire barrier for masonry construction.
ARC Fire Stop Slab provides up to two hours' fire integrity horizontally or vertically within external masonry walls, ideal for use at separating floor levels. Manufactured from rock fibre mineral wool insulation with a class ‘O’ reinforced aluminium foil facing to both sides, offering excellent resistance to smoke.
It is fixed using ARC Fixing Spike, which is fitted to the external surface of the inner leaf. The ARC Fire Stop Slab is then impaled onto the spike.
