These Type P intumescent pillows form a seal around openings for pipes and cables, protecting against fire and smoke. Envirograf's Intumescent Fire & Smoke Stop Pillows activate at high temperatures, such as during a fire, expanding 3 times their size at low pressure, locking together with other pillows without pushing them out of place, sealing an opening against the spread of smoke and fire. Resisting fire for up to 2 hours, they allow extra time for buildings to be evacuated and help prevent further damage.

Can be fitted vertically and horizontally in any position, with no special skills or tools needed. Push around pipes and wires where they pass through walls, ceilings and floors to seal the gap.

Made from glass cloth and filled with fireproof sponge and intumescent material, the pillows are non-fibrous and dust-free, making them safe for use in walls, ceilings and floors around clean, sterile areas as well as computer rooms.

The pillows can be fitted with cord and tags to secure them to trunking and cable trays, and are easy to remove and refit.
