Unilin Safe-R SR/UF 100mm Phenolic Floor Board

100mm 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 excellent thermal conductivity of just 0.020 W/mK, enabling superior U-Values in flooring insulation systems.

Floors lose considerable heat downwards without adequate insulation protection. The 100mm Unilin SR/UF Phenolic Floor Insulation Board provides an effective solution, dramatically improving U-values for both new construction and existing floors. Beyond thermal performance, this board offers lightweight handling, simple installation, robust compressive strength, and minimal heat loss—combining to create a high-performance flooring insulation product.

Handling, Cutting, and Storage

Unilin Phenolic Insulation Board must be stored on an elevated, clean, level surface and kept protected from weather conditions. Polythene wrapping alone cannot provide sufficient protection from outdoor elements. Take appropriate care during storage and construction to maintain the insulation's integrity. Wear suitable personal protective equipment (PPE) when handling insulation materials.
