We also manufacture the DecraLed® self-adhesive lead strip, Decra Fused Tiles, Decra Bevels and Decraglow colour films for application and decoration of glass in single and double glazing. Our British products are the highest performance, preferred by manufacturers and highly competitive in the worldwide market.

Originally founded in 1979, the business has seen substantial growth over the years and operates from 4 rapidly-expanding sites in Birmingham, Wigan, Kent and Belfast. Thermoseal Group is entirely privately-funded and growth is through re-invested profit. We have our own distribution network of warehouses, vehicles and drivers to deliver components in the UK and our expanding export operations are carried out directly from our main manufacturing site in Wigan. We now deliver to 40 countries within Asia; Oceania; Europe; North America and South America.
