Extended cavity fire barrier performance within rainscreen facades.
For use within open state cavities (e.g. rainscreen systems), allowing ventilation and drainage of the cavity under service conditions.
Polythene sleeved, ROCKWOOL® stone wool fire barrier faced with high performance intumescent material designed for use within open state cavities (e.g. rainscreen systems), allowing ventilation and drainage of the cavity under service conditions.
Open state cavity barriers provide an effective fire barrier for ventilated voids up to 425 mm in depth. OSCB 120/25 delivers a fire rating of up to 120-minutes insulation and integrity with an air space of 25 mm.
The AIM OSCB 120/ 25 range has been tested to provide solutions that accommodate cladding rails interrupting the line of the barrier.
