XtroLiner Underfloor PIR offers insulation performance with a thermal conductivity of 0.021 W/mK. The floor in any building is an area of considerable downward heat loss when not properly insulated.
XtroLiner Underfloor will significantly improve the U-Value of new and existing floors. It is lightweight and combines high compressive strength with low thermal conductivity, providing a solution for floor insulation.
