Intumescent Fire Stop Pillow

A reinforced glass cloth intumescent pillow. Filled with fireproof sponge and intumescent material for effective smoke and fire protection. Expands to 3 times its original size in a fire, sealing gaps around services in walls, floors and also ceilings. The intumescent pillows will expand at low pressure, then lock together to seal off fire without pushing services out of alignment. Also available with tags or loops for reinforced security.

Our intumescent pillow has effective durability in varying weather conditions, and will not degrade. This makes them suitable for blockwork, brickwork and other structures requiring fire protection to seal voids and gaps. Ideal for computer rooms, including sterile areas of buildings.

Due to their soft, flexible material, you can remove or refit the intumescent pillows where necessary. In the event of fire where intumescent pillows become attacked by flames, replace them with new pillows in order to restore lost fire properties to the structure. Smoke is also effectively prevented from spreading through intumescent, able to protect occupants from dangerous smoke inhalation and safely allow for evacuation.

  • A good temporary or permanent solution, providing up to 2 hours fire resistance

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.
