Fire and Sound Trap for Electrical Boxes

Available: In Stock

    Where conduits pass through fire-rated ceilings and walls, it is a requirement to terminate each side with a BESA or universal box fitted with intumescent gaskets to stop fire penetrating. It is also a requirement to fit intumescent gaskets in the back of metal switch/socket boxes where they are back-to-back and cables pass through the wall. Our extensive range of expanding intumescent gaskets and linings can be used with a wide range of standard electrical boxes.

    – Solutions for both plastic and metal boxes, providing up to 4 hours protection- Compatible with single or double socket or switch boxes, BESA boxes, universal conduit boxes and ceiling roses
    – Complies with IEE Wiring Regulations, bringing standard boxes in line with Document B

    Intumescent gaskets are essential in metal or plastic boxes where
    cables pass back through a wall. Gaskets must be fitted to all dry lining boxes in
    partition walls. Without these gaskets fire can spread into the partition within 4-5
    minutes. Where cables run through back to back boxes in brick or block walls, flames
    can pass through within 6 minutes, resulting in a wall or partition only 6 minutes of
    fire integrity.
    Gaskets for use inside metal or plastic boxes are made to the size of the box and
    come with self-adhesive fixing on the back. Once the backing paper has been peeled
    off the fixing strip, the gasket can be adhered to the inside of the box. Holes can be
    cut into the gasket with a sharp knife to receive cables, or the gasket can be cut to fit
    the back of the box if cables are already fitted. Dry lining boxes in walls have two
    pads per box, made to size and adhered top and bottom.
    Plasterboard ceiling rose boxes can be protected by means of an intumescent cover
    which folds up and is passed through the hole in the ceiling. A hole is then cut in the
    cover to receive the cables, which are then pulled through the cover, box and ceiling
    before connecting the ceiling rose.
    Ceiling rose gaskets to fit over the ceiling rose or hook plate should be fitted where
    more than two cables pass through the ceiling. A hole is made in the gasket through
    which the cables are passed. The backing paper of the self adhesive fixing strip is
    then peeled off and the gasket is adhered to the ceiling. The pendant or light fitting
    can then be fitted.
