Unilin Safe-R SR/UF 40mm Phenolic Floor Insulation

40mm Unilin Safe-R SR/UF Phenolic Floor Insulation Board delivers premium rigid phenolic insulation with outstanding fire performance characteristics. Featuring dual aluminium facings with low emissivity properties, this board achieves an exceptional thermal conductivity of just 0.020 W/mK, enabling superior U-Values in flooring insulation systems.

Uninsulated floors allow significant heat to escape downwards, compromising energy efficiency. The 40mm Unilin SR/UF Phenolic Floor Insulation Board transforms both new and existing floors by delivering improved U-values and thermal performance. This solution combines lightweight handling with straightforward installation, robust compressive strength, and minimal thermal conductivity—creating an exceptionally efficient flooring insulation product.

Handling, Cutting, and Storage

Unilin Phenolic Insulation Board must be stored on an elevated, clean, level surface and kept sheltered from weather conditions. Polythene wrapping alone cannot protect against outdoor elements. Take appropriate precautions to protect the insulation during both storage and construction phases. Wear suitable personal protective equipment (PPE) when handling insulation materials.
