"formPartDetail:partDetailTabSet:0:j_idt234:0:j_idt236">SpecSeal 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. 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.

• Intumescent: expands in all directions for a tough, tight seal
• Reinstallable for easy retrofitting of cables
• Single-side application makes installation easy for tough access openings
• Intumescent coating on all sides for faster expansion and easier installation
• Heat-sealed poly cover protects core and makes pillows slide in and out with ease
• Superior air leakage ratings
