This high-performance multi-purpose insulation board from Celotex is ideal for a wide range of applications such as masonry walls, solid floors, flat roofs, pitched roofs, steel framed and timber framed systems and more. It is manufactured from rigid polyisocyanurate (PIR) and is a convenient solution due to being easy to handle, cut and shape.
With a remarkable thermal conductivity of 0.022W/mK, this incredibly versatile insulation board delivers excellent thermal performance. This means it can effortlessly meet the required uValue while remaining slimmer than most similar products on the market. This Celotex insulation features an innovative low-emissivity foil facing which considerably boosts thermal performance in sealed cavity air spaces and helps to enhance the potential uValue.
Designed to the highest standards in the industry, this Celotex insulation board has been approved by the British Board of Agrément (BBA) as suited for use in defined roof, floor and wall applications when installed, used and maintained as depicted in the certificate. Additionally, it has a Building Research Establishment (BRE) Green Guide Rating of A which ensures that it will improve your environmental performance. What's more, this insulation also provides reliable long-term energy savings for your home.

Can you use this for insulation under a concrete floor slab?

Yes this can be used under a concrete floor slab. A damp proof membrane (DPM) is laid first, followed by the insulation, a polythene vapour control layer (VCL), then the concrete slab.
