Pemko S88D21 Adhesive Perimeter Gasketing Dark Brown

Product Description

The PEMKO S88D21 is an adhesive-backed perimeter gasketing strip finished in dark brown, designed to seal the head and jamb perimeter of door frames against air infiltration, dust, light, and sound. At 252 inches (21 feet) per unit, it provides enough material to seal a standard commercial or residential door opening in a single package. The pressure-sensitive adhesive backing allows for tool-free installation directly to the door frame stop. Licensed contractors and door hardware specialists typically handle installation in both new construction and retrofit applications.

Perimeter gasketing of this type is used on exterior and interior door assemblies where a continuous seal around the frame perimeter is required. Common applications include commercial office entries, hotel corridors, residential exterior doors, and any opening where air, light, or sound control is a priority. The dark brown finish is suited to wood-tone door frames and is consistent with PEMKO architectural finish standards.

Installation Notes

Perimeter gasketing is typically installed by door hardware specialists or general contractors during new construction or door retrofit work. Clean and dry the door frame stop surface thoroughly before applying the adhesive strip to ensure proper bonding. No special tools are required, but a roller or firm hand pressure along the full length improves adhesion. Consult applicable building codes for fire-rated or smoke-labeled assemblies, as gasketing products used in fire door applications must meet specific labeling requirements.
