XT/PR-UF
Ground Supported and Suspended Floors
Applications:Floor / Solid & Suspended
XT/PR-UF
The floor in any building is an area of considerable downward heat loss when not properly insulated. XT/PR-UF will significantly improve the U-value of new and existing floors.
Thin-R Underfloor XT/PR-UF is lightweight, easy to install and combines high compressive strength with low thermal conductivity, providing a high performance solution for floor insulation.
