Description
Pemko S44 Silicone Adhesive Perimeter Gasket
The Pemko S44 Silicone Adhesive Perimeter Gasket is a high-performance sealing solution engineered for tighter door frames while maintaining exceptionally low closing force. Made from extruded high-temperature silicone, it compresses to seal gaps as small as 1/16″, helping protect door assemblies against smoke, fire, air infiltration, sound, and weather.
Designed for commercial applications, the S44 begins compressing at 5/16″ and provides a reliable perimeter seal along the top and sides of the door frame. Its self-adhesive backing allows for fast, secure installation, while the durable silicone construction resists extreme temperatures, sunlight, ozone, UV exposure, fungus, and mildew. Self-extinguishing and non-toxic, this gasket delivers long-lasting performance in demanding environments.
