Pemko S88BL20 240" 20' Adhesive Perimeter Gasketing Black Finish

The S88BL20 adhesive perimeter gasket seals gaps up to 1/16" around door frames to prevent air infiltration and maintain building envelope integrity. This silicone gasket installs on door frames with peel-and-stick adhesive backing. Pemko designed this weatherstrip to solve energy loss problems at door perimeters where traditional mechanical seals won't fit.

The 20-foot roll provides enough material for most standard door openings. Black finish matches common door hardware. Silicone construction handles temperature extremes and UV exposure better than rubber alternatives. This gasket compresses easily under door pressure to form an effective seal.

This gasket meets UL 10C fire door testing standards and UL 1784 air leakage requirements. ANSI/BHMA A156.22 Door Gasketing certification confirms durability. ASTM E283 air infiltration testing validates sealing performance. GREENGUARD Gold certification ensures low chemical emissions.

Fire-rated door assemblies require specific gasketing to maintain their UL 10C listing during annual inspections. For broader code context on building safety requirements, see NFPA 101 Life Safety Code egress standards.
