The Celotex High Performance Insulation Board is an ideal solution for contractors and DIYers looking to enhance the thermal efficiency of roofs, walls, and floors. Delivering an impressive thermal conductivity of 0.022W/mK and an R-Value of 5.90m2K/W, it provides substantial insulation performance within a manageable 130mm thickness; however, users should note that its rigid construction requires precise cutting to ensure seamless installation in irregular spaces.

Yes, its compressive strength of 140 kPa is suitable for many domestic ground-bearing floor applications.
The foil facing acts as a low-emissivity layer, but you should consult local building regulations to determine if an additional vapour control layer is required based on your specific assembly.
Use a fine-toothed saw or a long-bladed insulation knife for clean, straight cuts.
The board has an R-Value of 5.90m2K/W.
Yes, the product complies with BS EN 13501-1 standards for fire classification.
Yes, this board is specifically engineered for use in flat roof, pitched roof, and wall applications.
Use a straight edge and a sharp utility knife to score and snap the board to the required width.
Fill joints with a suitable expanding foam or use high-quality foil tape to maintain thermal continuity.
Check for thermal bridges where the insulation may have been compressed or damaged during installation.
Installation requires standard carpentry tools, such as a sharp fine-toothed saw or insulation knife for cutting. Ensure the surface being insulated is dry and clean to allow for proper adhesive or mechanical fixing. While the board is robust, avoid walking directly on exposed boards before the finished floor covering is installed to prevent indentations. Store the boards in a cool, dry place, ideally off the ground, and keep them protected from prolonged direct sunlight or moisture during the construction phase to maintain the integrity of the foil facing.
