550 Series Firestop Systems have been developed to provide up to four hours firestopping at the junctions of compartment walls and floors. The systems have been tested in accordance with BS EN 476-20.
553 Firestop Strip is a no compression, tight fitting (extended width) strip for rectangular voids. It is used in cases where the fire resistance of a deck horizontally is less than the fire resistance of the wall itself.
