Fire retardant polyurethane foam sealant is a compressed tape of polyurethane foam, impregnated with an acrylic, fire retardant resin. The tape is coated on one side with a pressure sensitive adhesive, which is protected with a release paper. Upon installation, the release paper is peeled and removed from the tape, exposing the adhesive and installed, adhesive-side toward the window or door casing being fit into the building opening. Once installed, the tape slowly returns to its original, uncompressed, state, thereby forming a tight seal around the window or door.
