A reinforced glass cloth intumescent pillow filled with fireproof sponge and intumescent material. Expands to 3 times its original size in a fire, sealing gaps around services in walls, floors or ceilings. Pillows will expand at low pressure, then lock together to seal off fire without pushing services out of alignment.


– Ideal for awkward gaps as it can be compressed
– A good temporary or permanent solution, providing up to 2 hours fire resistance
– Can be fitted with cord and 100mm retention tag to fix the pillows in place as a permanent solution
– Great for use around cables which are regularly adjusted
– Non-fibrous, dust-free materials are suitable for use in sterile areas or clean rooms

Application Instructions

The pillows can be folded to fit between pipes and services. For vertical openings i.e.
In walls, build the pillows in rows and staggered in formation, compressing each pillow
to ensure all gaps are filled to stop the passage of smoke. For horizontal openings
i.e. floors, build together as in walls, but where openings are greater than 700mm x
400mm, to prevent sagging, supply additional support by fixing wire mesh into the
opening first.
