Founded 50 years ago, Dixon International Ltd is an award-winning innovator and manufacturer of specialized construction products. We were the first to develop aluminium and elastomeric draught seals for doors & windows in the early sixties. We were the first to launch fire and smoke seals for fire doors worldwide in the seventies. We coined the term "Intumescent" and went on to win four Millennium Product Awards from the Design Council for our advances in intumescent technology by international standards. Our technical strengths have led to our developing bespoke products for clients as diverse as the Thames Barrier, English Heritage and the Channel Tunnel. We intend to innovate into the future to save more lives in fires and to reduce energy costs. We are in a major R&D programme to bring further advances in fire safety glazing, in fire door seals, in energy efficiency and acoustic protection.
