About Us

Seymour Manufacturing International has been saving energy and money for some of the world’s biggest and best known businesses since the 1980s.

Our client list is a who's who of big-name brands, including retailers such as Waitrose, Morrisons, ASDA, Sainsbury's, Marks & Spencer, Co-op and Lidl.

We also work with the NHS, the Ministry of Defence, and have become a leading thermal insulation supplier for the protection of food, chemicals, agricultural and home delivery products.

It’s all thanks to Tempro, SMI’s remarkable lightweight thermal insulation material which has been scientifically proven to cut energy loss by between 25 - 60%, depending on product/environment.

No wonder it was the first choice for intrepid explorer Sir Ranulph Fiennes when he headed off towards the South Pole, and needed to protect his living quarters, tractor units and portable laboratories from dangerous sub-zero temperatures.

From supermarket coldrooms to food haulage fleets, blood banks and chemical installations, SMI specialises in finding simple solutions to temperature maintenance problems, helping clients to save money, and energy in the process.

From our new headquarters in Telford, we are active all over the UK as well as in France, Germany, Spain, Portugal, Poland, the Czech Republic, Switzerland, Belgium, the Netherlands, Ireland, Sweden, Slovakia, Russia, Saudi Arabia, and South Africa.

Don’t just take our word for the thermal qualities we claim of our products – they have been tested by Intertek and validated by the world-renowned Campden BRI.

All of our products are easily cleaned, anti-fungicidal, of hard wearing construction, UV stabilised and flame retardant – and most can be made to order to fit any shape, size, or application.
