Description

Celotex XR4000 is a multi-purpose insulation board developed to provide simple solutions for overcoming localised thermal bridges.

With low emissivity foil facings, XR4000 is manufactured from rigid polyisocyanurate (PIR) using a blend of blowing agents that have zero ozone depletion potential (zero ODP) and low global warming potential (GWP). Our 12mm product positions Celotex as the manufacturer of the broadest range of product thicknesses, from 12mm-200mm.

Application

The insulation shall be Celotex XR4000 comprising a polyisocyanurate rigid foam insulation core, with a thermal conductivity of 0.022W/mK and low emissivity aluminium foil facings on both sides. XR4000 is A+ rated when
compared to the BRE Green Guide 2008 and is CFC/HCFC free with zero ODP and low GWP.

Celotex XR4000 can be specifed for use in a variety of applications such as pitched roofs, flat roofs, solid masonry walls, floors, timber framed & steel framed systems.
