SpecSeal® SSB Firestop Pillows are through-penetration firestop products resembling small cushions or soft bricks designed for medium to large openings. Ready-to-install by compressing and stacking in brick-like fashion, these intumescent and highly resilient pillows consist of a mineral fiber core sealed with a water-resistant intumescent membrane, then heat-sealed in a tough, non-irritating, fire-retardant poly bag.
Key Features & Benefits
- Intumescent technology – expands in all directions for tough, tight seal
- Reinstallable design – allows easy retrofitting of cables without damaging firestop seal
- Lightweight construction – easy installation and handling
- Easier wire screen requirements – simplified installation for large openings and 3-4 hour ratings
- Heat-sealed poly bag – strong, durable outer protection
- No sewn seams – eliminates unraveling, tearing, and irritating fiberglass exposure
- Monolithic encapsulated core – no loose fill materials for cleaner installation
- No special tools required – simple compression and stacking installation
- Superior air leakage ratings – virtually airtight seal performance
- Zero VOC content – environmentally safe with no volatile organic compounds
Applications
- Medium to large openings containing various penetrating items
- Cable installations – data, communications, power, and control cables
- Pipe penetrations – insulated metal pipes and various piping systems
- Conduit and innerduct installations in electrical systems
- Bus ducts and HVAC ducts in commercial building applications
- Cable tray penetrations requiring flexible sealing solutions
- One-sided shaft wall installations where access is restricted
- Retrofit cable installations without damaging existing firestop seals
