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. The fire pillows are ideal for sealing Cable Trunkings, Small, Medium and Large Cables, Cable Trays, Cable Ladders and Metallic Pipes that penetrate concrete, block, and masonry walls also tested in concrete floors.

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

These intumescent pillows have been independently tested in accordance with BS476: Part 20: 1987 and can provide up to 4 hours fire integrity.

Also tested to EN1366-3.

They contain no asbestos or halogens.

Penetrations up to 600mm2 - 4 hrs and up to 1000mm2 2 hrs fire resistance.

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.

For further information on installation requirements please review the installation video (Floor and wall Penetration) or contact the technical team on: tel 01329 844 500 or email
