WWG Window Wall Gasket
SpecSeal Window Wall Gasket is an intumescent rubber gasket embedded with glass fiber mesh designed for edge of slab firestopping in window wall construction. Window Wall Gasket installs between the floor and aluminum framing directly behind the slab closure panel. Under fire exposure, Window Wall Gasket rapidly expands (intumesces) to form a dense, highly insulative char to seal the void against the spread of flames and hot gases. Patent Pending
