90mm Celotex

90mm Celotex CW4000 Partial Fill Cavity Wall (5/pack)

An insulation with partial fill option for wall cavities comprised of bricks or at 90 millimeters Celotex CW4000 Partially Cavity Wall (5/pack). Cavity Wall (5/pack) comes with a tough Polyisocyanurate (PIR) insulation board with outstanding thermal performance and is able to be used in new structures , as well as extensions.

It is designed to to fit between the connections of a cavity wall. it is extremely light and strong making it easy to move and carry and also to install in site.CE-marked 90mm Celotex CW4000 Partially Fill Cavity Wall (5/pack) is approved by the British Board of Agreement for the construction of cavity walls. It is manufactured at our original location in Hadleigh or at our new facility located at Eggborough (opened in the year 2018.) It is certain that it will provide durable sustainable energy savings over the long term that will help in the process of making your home a future-proof home's structure.
