PIR Insulation

XT/UF

Ground Supported and Suspended Floors

Applications:Floor / Solid & Suspended

Thin-R XT-UF

XT/UF

The floor in any building is an area of considerable downward heat loss when not properly insulated. XT/UF will significantly improve the U-value of new and existing floors.

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