What is Celotex?

Celotex is the UK’s leading brand of rigid insulation, known as polyisocyanurate (PIR). At the forefront of low carbon solutions to the construction industry at home and abroad, Celotex products are making positive contributions to the global drive towards climate change improvements.

Celotex is made by blending together materials to form a rigid foam product. The heat generated during the reaction enable gases to evaporate and become trapped within cells delivering premium thermal performance characteristics.

Offering superior thermal performance to most products commonly available, Celotex is available in an extensive range of thicknesses suitable for a wide range of applications from top-up loft insulation, to floors, walls, pitched and flat roofs.

Uniquely Celotex products are now offered as zero-carbon solutions for you to buy here for your home. We simply neutralise the emissions incurred during the manufacture of the product through our carbon-offsetting activity to give you the complete peace of mind that you really are buying into elements you would expect from a brand leader.
