The Masonry Party Wall Cavity Stop Sock 552 is designed to prevent passage of fire through concealed voids within the external fabric of a masonry wall construction, but more specifically where the junction is formed between the external cavity and the party wall cavity. The polythene enclosed rockfibre barrier is manufactured in bespoke sizes to suit the specified cavity width. The barrier is held in place under compression between the inner block work and outer masonry leaf.
