Cables can ignite quickly during a fire, spreading flames and smoke up trunking and through fire barriers to other parts of a building. Using Envirograf Intumescent Pads helps protect against fire and smoke, expanding in a fire to seal the space inside trunking for up to 3 hours of protection. Ensure to use inside trunking where it passes through penetrations.

The pads take up very little space and fit simply on either side with double-sided adhesive strips, out of the way of cables and needing no maintenance.

Indentification Labels

The product identification labels supplied must be used in order to indicate to building control officers and fire officers that protection has been applied to the penetration, and to comply with the current 17th Edition of IEE Regulations.

Application

Single Pad Configuration

For trunking sizes not exceeding 100mm x 100mm, only one intumescent pad is required per penetration, as indicated by the blue shape opposite. 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.

Twin Pad Configuration 

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