Electrical socket fire and sound trap
Unprotected openings for electrical sockets will reduce the acoustic performance of walls and compromise the resistance to fire. To comply with Documents B and E of the current UK Building Regulations, the integrity of the wall must be maintained, and this can be easily achieved with the new Envirograf® Fire and Sound Trap (FST). This versatile product will encase airborne and impact sound and, in the event of a fire, the product will entrap the flames within the socket box for up to two hours, ensuring that there is no penetration of flames and smoke through the socket and into the wall cavity.
This streamlined product, with its double action design, will help to save lives and combat both airborne and impact sound. It is extremely flexible and it can be easily fitted in seconds to all types of electrical socket boxes, thus saving valuable installation time. The new Passive Fire Products, Envirograf® Fire and Sound Trap (FST) can be fitted internally or externally to both UPVC and metal socket boxes and it has been tested in accordance with the principles of BS EN1366-3, achieving two hours of fire protection.
