Pemko

Founded in 1952 in Ventura, California, Pemko Manufacturing Company established itself as a pioneering manufacturer of weatherstripping and door sealing products before being acquired by ASSA ABLOY Group in February 2007 for an undisclosed amount, following annual sales of $55 million with 330 employees. Specializing in door perimeter solutions, Pemko manufactures a comprehensive line of thresholds, gasketing products, door bottoms, astragals, continuous hinges, and sliding door hardware designed to control air infiltration, smoke, fire, sound, and light transmission. The company's flagship products include the S773 triple-fin silicone adhesive gasket (BHMA certified, UL10C fire-rated for positive pressure, UL1784 smoke tested), S44 and S88 SiliconSeal adhesive gasketing meeting NFPA 105 standards for smoke door assemblies, and S442 combination fire and smoke seals rated for up to 3-hour fire door assemblies. Their automatic door bottom series (including models 411, 412, 420, and 434) provide ADA-compliant solutions with various insert options including nylon brush, sponge EPDM, silicone, and PemkoPrene materials. All products undergo rigorous testing including ASTM E-283-04 air infiltration testing (achieving 0.09 CFM per foot of crack), ASTM E90 sound testing, and compliance with UBC 7-2 and NFPA 80 requirements. As an ASSA ABLOY Group brand, Pemko continues to operate from its California base, offering GREENGUARD Gold certified products and maintaining its reputation for durable, high-quality commercial door solutions that meet or exceed industry specifications for fire, smoke, acoustic, and environmental control applications.
