Intumescent fire pillows in situ


Our fire pillows are manufactured from a hard wearing specially treated glass cloth filled with a mixture of mineral fibre and reactive expansion (intumescent) agents.

On exposure to high temperatures from a fire the intumescent material expands and then hardens to provide a complete and durable seal against the passage of fire, smoke and hot gases.

Intumescent Fire Pillows can be used for creating either temporary or permanent fire barriers and are ideal for sealing cable trays and ducts that penetrate fire resistance structures.

Suitable for use in telephone exchanges, computer rooms and other areas where cable services are frequently modified.

Suitable for the sealing of Cable Trunkings, Small, Medium and Large Cables, Cable Trays, Cable Ladders and Metallic Pipes

Health and Safety

Care should be taken to avoid puncturing the pillows as dust generated may cause irritation to skin or eyes. Wear gloves and dust mask if handling damaged pillows.
Keep out of reach of children. Normal good industrial and personal hygiene practices should be observed.



Fire pillows sealing wall penetation.

Fire pillows are quick and easy to fit and can be removed for re-use or allow new services to be passed through the penetration, to maintain the integrity of the structure simply re-fill the void with the pillows.

In all situations the pillows should be fitted on a staggered formation and be packed tightly into the opening.

If the pillows are to be used in floor penetrations a support mesh must be used - see installation sheet for further details.
