Product Information

Quinn Therm QF PIR Insulation is a high performance, fibre free board, with a rigid thermoset insulation core and faced on both sides with a low emissivity composite foil facing.


The high compressive strength of Quinn Therm QF enables it to withstand the dead and imposed loads transmitted through the floor.


Quinn Therm QF is suitable for new build and refurbishments projects in both domestic and commercial build. With specific properties that optimise the performance of underfloor heating.


For suspended timber floors in particular, Quinn Therm QF reduces heat loss by an air infiltration method, making it the ideal solution for upgrading the thermal performance of existing floors.
