Intumescent Pads for Trunking

Intumescent pads with adhesive on one side are designed to be fixed to the inside of plastic or metal trunking. Designed for multi-opening PVC trunking with services passing between walls or ceilings. The intumescent will expand in a fire and seal the inside of the trunking, thus preventing spread of fire.

Specifically designed to compress cables and fill the entire width of the trunking to stop fires spreading.

An excess of wires causes an electrical hazard if not properly wired or supported. Fires quickly spread through buildings in the event that combustion occurs.  Where cables or electrical services pass through trunking, there is a risk of fires spreading from overheated wires.

  • Installing intumescent pads creates a fire seal within trunking, able to effectively compartmentalise fires.
  • It’s lightweight, flexible material makes it easy to cut to size as required.

An alternative product for protecting cables is Product 110 – Firoblok for Plastic Trunking.

Application Instructions

For trunking sizes not exceeding 100mm x 100mm, only one intumescent pad is required per penetration. For trunking sizes equal to or exceeding 150mm x 150mm, two intumescent pads are required per penetration.
The self- adhesive backing on the pad is revealed by removal of the protective covering paper, taking care
not to touch the adhesive surface against fingers, dust, etc. for
maximum adhesion strength. The pad is placed inside the trunking
and within the penetration area, and then pressed firmly against
the inside surface at one side of the trunking.
