Fire socks are a widely used, practical on-site solution to close voids at junctions. Designed to prevent fire penetration, aid reduction of sound transmission and help maintain the thermal integrity of the insulation requirements under building regulations in masonry, block and brick, timber frame and steel cavity wall structures.

All Dacatie Fire Multi Socks are manufactured in the UK by MDL Insulations Ltd and consist of stone wool slab which has a fire classification of Euroclass A1 tested to BSEN13501-1. The Rock Slab is encapsulated in recycled polythene sleeves and will not add to the propagation of fire.
