For limiting the spread of smoke and flames in external masonry walls, these ARC Cavity Stop Socks reduce the effect of flanking noise pollution at wall junctions and have a masonry fire rating of four hours. They are easily compression fitted within a masonry cavity during the development of brick and block work, therefore, mechanical fixing is not required.
Fabricated from low resin, non-combustible rockfibre mineral wool insulation, this product has a sleeve of polythene that encapsulates it and allows for on-site weather protection. It is also possible to remove the sleeve without hindering barrier performance.
