Pemko S88D18 216" 18' Adhesive Perimeter Gasketing Dark Brown Finish

The S88D18 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 directly onto door frames using the included adhesive backing, creating a compression seal when the door closes. Pemko designed this 18-foot length gasket to address weatherization requirements and air leakage control in commercial and institutional buildings.

The dark brown finish provides a professional appearance while the silicone material maintains flexibility across temperature ranges. This gasket compresses under door pressure to block air movement through perimeter gaps. Installation requires no mechanical fasteners due to the adhesive backing system.

This gasket meets UL 10C positive pressure fire testing standards and UL 1784 air leakage requirements for door assemblies. It also complies with ANSI/BHMA A156.22 door gasketing standards and ASTM E283 air infiltration testing protocols.

Fire door applications require gasketing that maintains ratings during UL 10C testing while providing air seal performance. For broader building envelope requirements, NFPA 101 compliance often involves controlling air movement in egress paths.
