Quinn Therm QW

Quinn Therm QW 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 low emissivity foil facings increase the thermal resistance an unventilated cavity adjacent to the insulation, reducing the overall U-value of the wall.

The good dimensional tolerances of the Quinn Therm QW PIR Insulation board enable it to be tightly butted to form a continuous layer of insulation.  Joints can then be easily taped with an aluminium foil tape to provide an effective vapour control layer.



  • Certified under BBA certificate number 07/4444
