Product Description

Stone Shield Fire Barrier EN is a wire-reinforced, high-density fire-resistant curtain manufactured using our proprietary basalt stone fibres. Designed to inhibit the spread of fire and smoke through building cavities, The addition of a second layer of foil further inhibits the spread of smoke and also improves the reduction in room-to-room transmission. it offers superior performance for both horizontal and vertical applications and meets the requirements of BS the latest EN 1364-1:2015
