The Everkem Diversified Products Intumescent Firestop Pillow is a lightweight, self-supporting device designed to seal medium to large voids around penetrating items. Each pillow measures 2" x 6" x 9" and features intumescent technology that expands when exposed to heat, creating an effective fire barrier. The pillow is ready to use out of the package and carries UL Classification, meeting ASTM-E814 standards for firestop applications.
This economical firestop device installs easily without special tools or mixing, making it ideal for retrofits and new construction projects. The pillow's intumescent material provides reliable fire protection while remaining lightweight enough for quick installation in walls, floors, and ceiling assemblies. As part of Everkem's EcoSeal product line, it's manufactured in the USA and designed for long-term performance in commercial and residential applications.
These pillows work well for sealing openings around cable trays, conduit bundles, and pipe penetrations where traditional sealants may be impractical. The 2" x 6" x 9" size handles most standard opening requirements while the intumescent properties ensure effective expansion during fire conditions to maintain the integrity of fire-rated assemblies.
