Celotex limited company history

In the 1970s, Celotex limited started developing the current product range, with limited production of rigid polyisocyanurate (PIR) starting at Hadleigh in 1980

Though PIR was an excellent product, it remained a niche product for many years.

However, in 2002, when stricter building regulations came in, they required ever-higher levels of insulation. So PIR became popular because it takes up less space than other materials.

The Hadleigh plant is now the largest PIR facility in the UK.
