Intumescent Trunking Pillows

Intumescent trunking pillows are used in situations where protection from cold smoke, as well as fire protection, is required in metal or plastic trunking that passes through floors and walls. The retention wire and tag are fitted inside the trunking as a safeguard against removal of the pillow during maintenance. The pillow is required to be re-inserted before the trunking lid is replaced. The cross-sectional area of the trunking should be no more than 50% full when using these pillows, to avoid overheating of the cables. Trunking pillows conform to BS476 Part 22.

Note: All trunking pillows are 100mm in length.
