What Astroflame does
Astroflame (Fire Seals) Ltd. is a UK-based B2B manufacturer and supplier of certified passive fire protection products and complementary safety solutions, headquartered in Fareham, England. The company designs, produces, and distributes an extensive portfolio spanning intumescent fire seals, smoke seals, pipe collars and wraps, fire-rated boards, mortars, mastics, coatings, fire pillows, duct sleeves, fire door hardware, acoustic seals, letterboxes, door viewers, finger protection devices, lighting fire hoods, and corner guards. Its core technology is intumescent chemistry—primarily graphite- and phosphate-based compounds that expand under heat to seal penetrations, door assemblies, and compartment walls, with fire resistance ratings from 30 minutes to 4 hours.
Astroflame generates revenue primarily through direct B2B sales to architects, contractors, installers, and fire inspectors under trade and wholesale pricing, with credit accounts, bulk discounts, and technical specification support. It supplements direct trade sales with international export to 50+ countries and an e-commerce storefront for smaller buyers. The product range is backed by independent third-party certifications including ISO 9001:2015, CE marking for the EEA, UKCA marking for the UK, Certifire approval, and UL-EU accreditation. The group also operates a sister brand, Astrodraft, for adjacent draught-proofing and weather-sealing products, and distributes third-party lines including Raven Products door seals and Interdens intumescent ironmongery protection.
