Product Details

FP333 Trunking Infill is a fire resistant compressible foam strip layered with high expansion intumescent material produced in three sizes. In a fire, the intumescent expands and hardens providing a fire and cold smoke barrier.

FP333 is designed to provide a permanent fire barrier within trunking boxes passing through fire compartment walls.

They are of particular use where there are regular changes in cabling requiring frequent removal and replacement, for example in computer or communication installations.
