Founded 50 years ago, Dixon International Ltd (DIG) is an award-winning innovator and manufacturer of specialised construction products. They were the first to develop aluminium and elastomeric draught seals for doors & windows in the early sixties and the first to launch fire and smoke seals for fire doors worldwide in the seventies. 

They coined the term "intumescent" and went on to win four Millennium Product Awards from the Design Council for advances in intumescent technology by international standards.

Their technical strengths have led to our developing bespoke products for clients as diverse as the Thames Barrier, English Heritage and the Channel Tunnel. 

DIG are in a major R&D programme to bring further advances in fire safety glazing, fire door seals, energy efficiency and acoustic protection.

Wood International Agency have joined DIG in multiple product development projects through their Sealmaster and Intumescent Seals Limited businesses. DIG's history and expertise in intumescent chemistry combined with WIA's knowledge in timber doorset systems, has led to some fantastic, robust evidence and designs being made available for door manufacturers.

Dixon International Group is an Official WIA Development Partner
