Details

The Celotex XR4120 insulation board is a premium rigid PIR board designed specifically for builders, contractors and developers who demand reliable thermal performance on serious projects. Its robust construction and high insulation value make it an excellent choice for enhancing energy efficiency in floor, wall and roof builds. Please note the product is supplied as boards only, with no additional fixings or accessories included.

Application

Ideal for a wide range of construction and refurbishment tasks, the XR4120 excels in ground floor insulation—whether concrete, block and beam, or timber joisted floors, including those with underfloor heating. It also fits neatly between studs in timber and steel-framed walls and can be installed between rafters in pitched roofs. Additionally, it is suitable for ventilated cold flat roofs installed from inside the building and is a strong option for upgrading existing timber or masonry structures to improve thermal efficiency.
