Trunking carries cables around buildings, passing through walls and floors and penetrating fire barriers. Use Envirograf Intumescent Trunking Pillows to restore integrity to a fire barrier and stop the spread of smoke and fire for up to 3 hours.

The pillows expand during fire at low pressure to seal the space from spreading smoke and fire, and should be used when steel and PVC trunking require cold smoke and fire protection.

Available in a selection of different sizes, complete with cord and retention tag to fix to trunking.

The retaining cord and lug fit inside the trunking, so if the pillow is removed the lid cannot be re-fitted without first replacing the pillow. 

The pillows will initially allow for 30% or less filling of cables and will then compress to allow for 50% cable fill without overheating the cables. If trunking is more than 50% full, then intumescent pads (Envirograf Product 26) should be used.

Application:

Intumescent Trunking Pillows are available in a range of sizes to suit standard sizes of trunking. Used where trunking passes through fire rated floors and walls. The pillows are simply pushed into place in the trunking where it passes through walls and floors.

Supplied with a fitted cord and lug which can be attached inside the trunking to ensure pillows will be refitted after removal for maintenance or access.
