90mm Celotex

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

A wall insulation with partial fill option for wall cavities comprised of bricks, that is 90mm Celotex CW4000 Partially Cavity Wall (5/pack). Cavity Wall (5/pack) comes in a robust polyisocyanurate (PIR) insulation board with outstanding thermal performance and is able for new constructions as well as extensions.

The dimension is designed to be able to fit between the cavities wall's ties. it is extremely light and durable which makes it easy to transport and handle as well as install in site.CE-marked 90mm Celotex CW4000 Partial-Fill Cavity Wall (5/pack) is affixed by the British Board of Agreement for the construction of cavity walls. It is manufactured at our original facility in Hadleigh or our current facility at Eggborough (opened in 2018) It is sure that it will offer long-lasting and long-term energy savings that will help in 'future-proofing your home.
