Xtratherm/Unilin 75mm XT/UF PIR Underfloor Insulation 2400mm x 1200mm

The Unilin Thin-R Underfloor XT/PR-UF is a high-performance, rigid polyisocyanurate (PIR) insulation board designed to cut downward heat loss through ground-supported and suspended floors.

Featuring a closed-cell foam core sandwiched between low-emissivity composite foil facings, it achieves an exceptional thermal conductivity. This allows you to achieve strict Building Regulation U-values with a significantly thinner profile—making it ideal for projects where floor build-up height is restricted. Lightweight, tough, and easy to handle, it provides long-term thermal efficiency for both new builds and retrofits.
