AIM OSCB 120/25 Red 1000 x 90 x 225mm to suit a 250mm cavity c/w fixing clips and course wound screws

£104.73
AIM Open State Cavity Barriers (OSCB's) are high-performance fire barriers that are manufactured from high-density Rockwool stone wool and faced with an intumescent strip. The intumescent strip expands quickly in the event of a fire to fully close the cavity, preventing the spread of fire. AIM OSCB's are designed and tested for use within ventilated rainscreen façades and timber frame construction. They allow free airflow and drainage, while still providing an effective fire barrier. AIM OSCB's offer a superior fire rating of up to 120 minutes insulation & integrity with ventilated air spaces within the cavity. They have been tested to TGD 19 & the general principles of BS EN 1363-1, and offer an effective fire barrier for ventilated voids up to 425mm in width. The AIM OSCB range is available to provide either a 25 or 44mm air gap. For simplicity the range also offers either a 60 or 120 minute rating for both Integrity and Insulation.

AIM OSCB 120/25 Red 1000 x 90 x 225mm to suit a 250mm cavity c/w fixing clips and course wound screws is backordered and will ship as soon as it is back in stock.

Applications

OSCB’s are a 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 normal conditions while providing up to 120 minutes insulation and integrity performance in the event of a fire.

The AIM OSCB range has been successfully tested to TGD 19 & the general principles of BS EN 1363-1 with a variety of substrates so that they can be used in a multitude of cavity wall constructions.

The OSCB 60/25 has also been tested for use vertically in a masonry cavity up to 425mm.

The AIM OSCB range has been tested to provide solutions that accommodate cladding rails interrupting the line of the barrier.
