The S88D25 adhesive perimeter gasket seals gaps up to 1/16 inch around door frames to prevent air leakage and smoke infiltration. This silicone gasketing installs on door jambs and headers where buildings need to meet air leakage standards and fire door assembly requirements. Pemko designed this 25-foot roll to address energy efficiency and life safety code compliance in commercial buildings.
The dark brown silicone material compresses against door surfaces to create an effective barrier seal. Installation requires no mechanical fasteners since the adhesive backing bonds directly to clean metal or wood surfaces. This gasket works on both fire-rated and standard door assemblies where air infiltration control is required.

This gasket meets UL 10C fire door assembly testing, UL 1784 air leakage standards, ANSI/BHMA A156.22 door gasketing requirements, and ASTM E283 air infiltration testing. GREENGUARD Gold certification confirms low chemical emissions for indoor air quality.
Fire door assemblies require gasketing that maintains both fire ratings and smoke seal performance under UL 10C positive pressure testing. For broader code context on egress requirements that affect door hardware selection, see NFPA 101 Life Safety Code standards.
