Resource: Fire Cavity Barriers

AIM’s OSCBs are polythene sleeved ROCKWOOL® stone wool and intumescent material designed for use within open state cavities (e.g. Rainscreen systems), allowing ventilation and drainage of the cavity under service conditions while providing up to 120 minutes insulation and integrity performance.

Open State Cavity Barriers offer an effective fire barrier for open state voids up to 425mm in width. Having been tested to the Association for Specialist Fire Protection (ASFP) Technical Guidance Document 19 (TGD 19) & the general principles of BS EN 1363-1, OSCBs offer an extended fire rating of up to 120 minutes insulation and integrity performance in open continuous ventilated air spaces of 25mm & 44mm.

AIM OSCBs are manufactured from high density ROCKWOOL® stone wool and faced with an intumescent strip and colour coded for ease of identification.
