Reinforced glass cloth pillows filled with fire-stopping sponge and intumescent material, sized to sit tightly inside PVC or metal trunking and compressed against the wires and cables. A retention tag attaches the pillow to the trunking so it can be withdrawn for access.
In a fire the pillow expands to around three times its original size, locking with adjacent pillows to seal the trunking bore without damaging the trunking itself. The filling is non-fibrous and dust-free.
- Up to 4 hours integrity
- Seventeen sizes, TP21 to TP126, all 100mm long
- Suits trunking carrying 30 to 50 per cent fill
