AIM Acoustic & Insulation Manufacturing’s Open State Cavity Barriers (OSCBs) allow free airflow and drainage and improve fire safety, providing a fire rating of up to two hours insulation and integrity in suitably supporting structures. AIM’s OSCBs, when installed behind a façade system, allow the ventilation that is necessary to prevent problems with condensation and allows drainage, but, in the event of a fire, heat activates an intumescent strip which expands quickly to fully close the cavity. Manufactured from high density Rockwool stone wool and faced with a higher performance intumescent strip, AIM’s range of four OSCBs provides either a 25mm or 44mm air gap and either a 60 or 120-minute rating for both integrity and insulation.
