PFC Corofil C144 Firestop Blocks

C144 Firestop Blocks are used to firestop profiles in roofing, cladding and composite floor decking. The blocks are manufactured to suit the specific trapezoidal shape. The width is determined by the fire rating of the masonry wall (see fire rating table in Datasheet). When firestopping steel beams or plasterboard partitions the block must fill the full width of the beam or partition.
