Pemko S88D 25FT Smoke Seal 25ft Dark Brown

Pemko Manufacturing Co S88D 25FT Smoke Seal is an essential solution for ensuring airtight and smoke-tight door applications. Designed to compress effectively from 1/4" to seal gaps as small as 1/16", this adhesive perimeter gasket is crafted from high-temperature silicone, making it suitable for extreme environments ranging from -58°F to 450°F. The S88D meets rigorous airworthiness standards, including FAR 25.853, and has been smoke tested in accordance with UBC 7-2 and UL 1784-01, ensuring compliance with NFPA 105 requirements. With an impressively low air infiltration rate of just 0.09 CFM/ft of crack, it’s a reliable choice for maintaining interior air quality and enhancing fire safety. This smoke seal is designed for use on Category B doors, requiring an additional edge sealing system, and can be applied to both steel and composite doors rated up to 3 hours. Its self-adhesive mounting type simplifies installation on the side of the frame, with a width of 1/2" and a height of 1/4". With its dark brown finish, the S88D 25FT Smoke Seal not only performs exceptionally but also blends seamlessly into various environments. Please note, this product has a limited shelf life and should be stored between 50°F and 100°F for optimal performance.
