About Fire and Sound Trap for Electrical Boxes

An intumescent fire and sound trap for electrical boxes for use in timber framed buildings. They are easy to install and will fit all cavity depths, single and double switch and socket boxes. Interior and Exterior options.

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 Envirograf® Fire and Sound Trap (FST) can be fitted internally or externally to UPVC socket boxes and it has been tested in accordance with the principles of BS EN1366-3, achieving two hours of fire protection.

  • It only takes seconds to fit
  • Offers acoustic, fire protection and prevents passage of air
  • Complies with documents B & E of current Building Regulations

Gaskets

Where socket outlets or switches are back to back in fire walls with cable or conduit passing through walls, gaskets must be fitted inside these boxes to stop the passage of fire.

In addition all boxes in plasterboard partitions need to have gaskets fitted. Where steel conduits pass through firewalls or floors, it is essential to terminate each side of the wall or floor slab with a BESA box or universal conduit box.

The intumescent gaskets fit into the back of the box, stopping the passage of fire and smoke from one compartment to the other.
