Description

Celotex XR4000 High Performance PIR Insulation For Floors, Walls & Roof Applications 120mm / 150mm

Unique and versatile, XR4000 is a high-performance, rigid polyisocyanurate (PIR) insulation board.

Available from stock up to 150mm thick, low U-values can be achieved without doubling-up insulation layers.

As well as being CE-marked, Celotex XR4000 is certified by the British Board of Agrément for floors, framed walls and pitched roofs.

Manufactured in the UK you can be confident of it providing reliable, long-term energy savings that help to ‘future-proof’ your building.

How does XR4000 perform?

The entire thickness range offers a low thermal conductivity (lambda value) of 0.022 W/mK, putting XR4000 among the best-performing widely-available insulation materials on the market.

In any of its intended applications, XR4000 will help to provide most of the thermal insulation performance - but the overall heat loss from a building element depends on all of the materials used and the way they’re installed.

Product benefits:

Celotex XR4000’s low emissivity aluminium foil facing can help achieve lower U-values when installed facing a clear air space within a construction. 

Like all Celotex products, XR4000 is a thermal insulation solution that can help to meet energy use and carbon dioxide emissions targets set by national building regulations.
