Insulation Warehouse can supply all of the Celotex XR4000 insulation range, many from stock in any quantities on 2-3 working days for delivery although some thicknesses may not be stocked in which case pack quantities may apply along with a slightly longer lead time. These Celotex insulation boards are made from Zero Ozone Depletion PIR foam inbetween layers of low emissivity foil with a grid printed on the foil which helps as a guide to cutting and for laying out underfloor heating pipework.

Celotex XR4000 has been designed with ' cut to fit ' applications in mind , such as between rafters in pitched roof insulation as either a singler layer or as part of a dual layer insulation system , also between joist flat roof insulation. These thicker insulation boards enable the user to achieve higher 'U' Values using 1 single layer. Also Celotex XR4000 can be used for other insulation projects such as Floor Insulation , for underscreed with a TB4000 upstand around the perimeter or suspended flooring applications in between joists. Wall Insulation in either timber framed or steel framed structures and also solid masonry wall insulation applications are other areas where Celotex XR4000 high performance insulation boards can be used to great effect.
