50mm Unilin Safe-R SR/UF Phenolic Floor Insulation Board

50mm Unilin Safe-R SR/UF Phenolic Floor Insulation Board delivers premium rigid phenolic insulation with outstanding fire performance. Featuring dual aluminium facings with low emissivity properties, this board achieves an impressive thermal conductivity of just 0.020 W/mK, enabling superior U-Values in flooring insulation systems.

Floors lose considerable heat downward without adequate insulation protection. The 50mm Unilin SR/UF Phenolic Floor Insulation Board transforms both new and existing floors by dramatically improving thermal performance. Beyond thermal efficiency, this solution offers lightweight handling, straightforward fitting, and combines robust compressive strength with minimal heat loss—delivering outstanding insulation performance for any flooring application.

Handling, Cutting, and Storage

Unilin Phenolic Insulation Board must be stored on a raised, clean, level surface and kept protected from weather conditions. Polythene wrapping alone cannot provide sufficient protection from outdoor elements. Take appropriate steps to protect the insulation during storage and throughout the building phase. Wear suitable personal protective equipment (PPE) at all times when handling insulation.
