Celotex 120mm Foil Faced Insulation Board

Celotex XR4120 is a multi-purpose insulation sheet developed to provide simple solutions for overcoming localised thermal bridges. Part of Celotex's XR4000 product range which covers sizes from 110mm - 200mm.

Manufactured from rigid polyisocyanurate (PIR) using a blend of blowing agents that have zero ozone depletion potential (zero ODP) and a low global warming impact. Covered on both sides with low emissivity foil facings.

A high-performance board that has been designed to be friendly to the environment and to reduce household energy bills. This also means a building's carbon footprint is also reduced. In the warmer months, the need for air-conditioning can also be reduced as Celotex have manufactured this product to keep unnecessary heat out.
