Click here to view full description

Celotex XR4000 is best used in  ‘cut-to-fit’ applications when adding insulation between rafters or joists. This insulation board is recommended as it obtains lower U-values with only a single layer of insulation. Thanks to its low emissivity foil facings, Celotex delivers enhanced thermal insulation performance within cavity air spaces and it features a heat conductivity of 0.022W/mK to provide more reliable insulation.

The XR4000 is multifunctional, which is why it’s also suited for use in floors and walls. Insulation boards for walls or floors are available in a broad range of sizes ranging from 20mm to 200mm of thicknesses. Thanks to the foil sides and its unbreakable polyisocyanurate (PIR) core, Celotex XR4000 is a reliable and lasting product.  The specific set of blowing agents used in the manufacturing process make this an environmentally-friendly purchase with zero ozone depletion potential (ODP) and substantially low global warming potential (GWP). 

Most of all, this Celotex insulation board will help you save on energy bills and lower the usage of resources like central heating and air conditioning by reducing heat loss and providing reliable long-term energy savings for your home or building. The Celotex XR4000 is devised to defeat cold spots and exhibit excellent performance in timber frame and masonry walls. Celotex insulation boards are made to satisfy current and future specifications set out by Building Regulations. It is one of most recommended insulation products used by contractors and builders and is employed for multiple uses for roof, wall and floor insulation.
