These intumescent and highly resilient pillows are installed in openings by compressing and stacking into the opening in a brick-like fashion. SpecSeal Firestop Pillows consist of a mineral fiber core material sealed with a water-resistant intumescent membrane. This coated core material is then heat-sealed in a tough, nonirritating, fire-retardant poly bag.
