Pillows & Cavity Barriers

Firestop pillows and cavity barriers provide passive fire protection for various openings within buildings to help limit the spread of fire, smoke, and hot gases. Fire barrier pillows can be used for sealing areas such as cable trays and bundles within data centers and telecommunications spaces. Cavity barriers are helpful within concealed cavities such as walls, floors, and ceilings, to reduce fire and smoke spread inside hidden areas.
