fire cavity barriers
Use of effective fire cavity barriers can enhance the fire safety of a building, particularly when specifying for project builds with multiple levels. Pura Facades® supplies market leading products from both SIDERISE® and TENMAT. The wide choice of fire break systems we supply work by blocking the airflow cavity behind the cladding, allowing effective control of fire by reducing the spread of flame.
