Pemko S44W SiliconSeal Adhesive-Backed Fire/Smoke Gasketing - White
The Pemko S44W is an architectural-grade adhesive-backed silicone seal engineered for superior fire, smoke, and sound containment. Extruded from high-temperature silicone, this "V" profile gasket is specifically designed for tighter door frames where standard bulb seals might interfere with proper latching. The crisp white finish provides a clean, professional look that blends seamlessly with white-painted frames or modern healthcare and office interiors.
High-Performance & Life Safety Features
- Extreme Temperature Resilience: Maintains full flexibility and sealing integrity in environments ranging from -58°F to 450°F, making it ideal for high-heat commercial applications.

Pro-Tip for Facility Maintenance
The Pemko S44W is the industry standard for remediating tight door clearances. Because it compresses down to a mere 1/16", it can often save a fire-rated opening from failing inspection due to "over-tight" frames. For a professional, permanent bond, always clean the frame header and jambs with an alcohol-based cleaner to remove grease and dust before application.
