Description

Integral electrical putty pads designed with intumescent for dry lining boxes. Electrical protection gaskets for BESA or universal boxes, where conduits pass through fire-rated ceilings and walls. BESA or universal boxes must have intumescent gaskets fitted to stop fire penetrating. Furthermore, metal socket boxes must have gaskets installed where they’re back-to-back. This also includes if cables pass through walls. Our extensive range of expanding intumescent gaskets and linings are ideal for a wide range of standard electrical boxes.

Advantages

– 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

Application Instructions

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.
