    Our 3M™ Fire Barrier Self-Locking Pillows are self-contained firestops ideal for medium to large through penetrations. Pillows feature Interlocking strips – installers can easily lock multiple pillows together to achieve precise fill and compression with no additional support required. Intumescent fire-rated pillows are designed to expand during a fire, locking themselves around vital components.

    Simply a Better Way to Firestop
    Presenting a simpler solution to the time, cost and material challenges of firestopping medium and large through penetration openings: our 3M™ Fire Barrier Self Locking Pillows combine intumescent fire-rated material and a range of sizes with interlocking strips that allow installers to easily lock multiple pillows together without tools. Installers can also cut and reseal the pillows in the field. This makes it easier to assemble ideally-sized firestops for specific penetrations in floors and walls, installed to the correct compressions for maximum effectiveness in new construction or retrofit applications. No wire mesh, steel cover plates or other additional support is required. The pillows are fully re-enterable and reusable – the interlocking strips can be released by hand, making it easy to reconfigure firestop pillows as additional services are added or relocated.
