Thin-R

XT/PR-UF (Floors)

PIR Insulation for Floors

XT/PR_UF (FLOORS)

Ground Supported & Suspended Floors

The floor in any building is an area of considerable downward heat loss when not properly insulated. Thin-R Underfloor will significantly improve the U-Value of new and existing floors.

Thin-R Underfloor is lightweight, easy to install and combines high compressive strength with low thermal conductivity, providing a high performance solution for floor insulation.
