25mm Unilin Safe-R SR/UF Phenolic Floor Insulation Board

25mm Unilin Safe-R SR/UF Phenolic Floor Insulation Board delivers premium rigid phenolic insulation with outstanding fire resistance. 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 for flooring insulation systems.

Floors lose considerable heat downwards without adequate insulation protection. The 25mm Unilin SR/UF Phenolic Floor Insulation Board transforms both new and existing floors by dramatically improving thermal performance. Beyond thermal benefits, this board combines lightweight handling, straightforward fitting, robust compressive strength, and minimal heat transfer into one high-performance flooring solution.

Handling, Cutting, and Storage

Unilin Phenolic Insulation Board must be positioned on a raised, clean, level surface and kept sheltered from weather exposure. Polythene wrapping provides insufficient protection if exposed to outdoor conditions. Take appropriate steps to protect the insulation during storage and throughout construction. Wear suitable personal protective equipment (PPE) whenever handling insulation materials.
