Open state cavity barriers allow the ventilation necessary within the wall construction. In the event of a fire, heat activates the intumescent strip which expands quickly to fully close the cavity. Certifix OSCB’s have been designed and tested for use within ventilated rainscreen façades and timber frame construction, allowing free airflow and drainage. Open State Cavity Barriers offer an effective fire barrier for ventilated voids up to 425mm in width. Having been tested to TGD 19 \u0026amp; the general principles of BS EN 1363-1, they offer a superior fire rating of up to 120 minutes insulation \u0026amp; integrity with ventilated air spaces within the cavity. The Certifix OSCB’s range is available to provide either a 25 or 44mm air gap. For simplicity, the range also offers either a 60, 90 or 120 minute rating for both Integrity and Insulation.","brand":"AIM","offers":[{"title":"Default Title","offer_id":51254621700260,"sku":"23259","price":61.7,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0657\/4496\/1700\/files\/AIM_OSCB_90-25_main.jpg?v=1771941756","url":"https:\/\/certifix.co.uk\/products\/aim-oscb-90-25-white-1000-x-90-x-209mm-to-suit-a-234mm-cavity-c-w-fixing-clips-and-course-wound-screws","provider":"Certifix","version":"1.0","type":"link"}
