About Us

Since the 1980s, Seymour Manufacturing International has been helping some of the world's largest and most recognisable brands save energy and reduce costs. Our esteemed client roster includes major retailers like Waitrose, Morrisons, ASDA, Sainsbury's, Marks & Spencer, Co-op, and Lidl, including a wide spectrum of different industries.

We also proudly support the NHS and the Ministry of Defence, establishing ourselves as a leading supplier of thermal insulation material for food, chemicals, agricultural products, and home deliveries.

Central to our success is Tempro®, SMI’s innovative lightweight thermal insulation material, scientifically proven by UK based testing centre to reduce energy loss by 25-60%, depending on the product and environment.

It’s no surprise that our insulation was the first choice for intrepid explorer Sir Ranulph Fiennes during his expedition to the South Pole, where he relied on it to safeguard his living quarters, tractor units, and portable laboratories from extreme sub-zero temperatures.

From supermarket cold rooms to food transport fleets, NHS, agricultural, military, and chemical facilities, SMI excels at delivering straightforward solutions to temperature maintenance challenges, enabling clients to save both money and energy.

Operating from our headquarters in Telford Shropshire, we serve clients across the UK and in countries including 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 it—our thermal products have been rigorously tested by Intertek and validated.

All our products are easy to clean, anti-fungal, durable, UV-stabilized, and flame-retardant. Most can also be custom-made to fit any shape, size, or application.
