Intumescent Trunking Pillows

Ensure premium fire safety and cable protection with Intumescent Trunking Pillows, expertly designed for use in steel or PVC cable trunking systems. Made from reinforced glass cloth filled with fire-stopping sponge and intumescent materials, these pillows expand up to 3 times their original size during a fire, forming a powerful intumescent seal. Ideal for preventing the spread of fire and smoke through trunking in walls, floors, and ceilings, they compress securely against cables and wires, making them especially useful in installations where cables are frequently adjusted. With a dust-free, non-fibrous construction, they're also safe for sterile environments such as hospitals and cleanrooms.
