Product description
SP FireStop OSCB 44 is a continuous intumescent strip fixed to the leading edge of a foil faced stone wool barrier, encapsulated by a weather-resistant polythene sleeve. It forms an open-state cavity barrier within a rainscreen system. In the event of a fire, the intumescent strip will quickly expand outwards to seal off the cavity, preventing the passage of fire and smoke.
SP FireStop OSCB 44 is designed and tested for use in conjunction with ROCKWOOL® RainScreen® Duo Slab and NyRock® RainScreen 032 only.
Installed horizontally and designed to ensure an appropriate open air space is maintained, SP Firestop OSCB 44 is suitable for cavity widths up to 425mm.
