Superior Performance Phenolic Insulation
SR/UF
Ground Supported and Suspended Floors
Applications:Floor / Solid & Suspended
SR/UF
Safe-R Under Floor SR/UF is a superior performance rigid phenolic insulation with low emissivity aluminium facings both sides and has a thermal conductivity as low as 0.020 W/mK, delivering excellent U-values in floors.
The floor in any building is an area of considerable downward heat loss when
not properly insulated. SR/UF will significantly improve the U-value of new
and existing floors. SR/UF is lightweight, easy to install and combines high
compressive strength with low thermal conductivity, providing a high
performance solution for floor insulation.
