STI SSB Firestop Pillows are through-penetration firestop products resembling small cushions or soft bricks.


These intumescent and highly resilient pillows are installed in openings by compressing and stacking into the opening in a brick-like fashion. STI SSB 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, non-irritating, fire-retardant poly bag.
