Simple Installation for an Exceptional Performance
Primarily used in top-side firestop installations, 3M™ Fire Barrier Tuck-In Wrap Strips are intumescent wrap strips that are UL tested and fire-rated for up to 3 hours. These flexible intumescent strips help prevent the passage of fire and smoke in new or existing non-metallic (e.g. plastic) pipe penetrations through walls or floor assemblies. We constructed these fire wrap strips to help eliminate the need for most of the materials and equipment usually required for labor-intensive, bottom-side firestop installations. These flexible foam strips slide easily into the openings around PVC, ccPVC and FRPP piping to fill tough areas and gaps. The tuck-in wrap strip has an adhesive-backed label to simplify installation and expands 100x in volume to help produce the best results possible.
