Firemaster Firebarrier

FireMaster FireBarrier products are cementitious materials designed for a variety of fire protection applications requiring strong and weather resistant exterior finishes.

FireBarrier 135 is available in two different dry powder versions used for either spayed or cast application. The dry powder is mixed with water, either in a spray machine for sprayed application, or directly when cast into shapes. The cast version allows linings to be pre-formed when spray application is not convenient or practical.

FireMaster FireBarrier 135 is suitable for cellulosic and hydrocarbon fires and has been fire tested in high-rise hydrocarbon fires of up to 1350°C.

FireMaster FireBarrier135 has been successfully fire tested to IMO A 754(18), ISO 834, RABT, Hydrocarbon modified (HCM) and RWS fire curves.
