Firestop pillows are passive fire protection items, used for firestopping holes in wall or floor assemblies required to have a fire-resistance rating. The products must be used in accordance with a valid certification listing, subject to listing and approval use and compliance.
Firestop pillows are used in openings that require frequent access (e.g., cable changes), requiring the removal of the firestopping and resealing after the changes are completed.
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.
