QUINN-therm QR (Quinn Roof) is a PIR (polyisocyanurate) insulation for creating warm pitched roofs by insulating above the rafters.
Insulating a pitched roof at rafter line - to create what is usually known as a warm roof - makes full use of the building volume by making the roof space available for occupation. Having the insulation at rafter line can also reduce stress on the structure and, even if the loft space is not utilised, there is still the benefit in having water tanks and other services within the insulated area.
QUINN-therm QR rigid insulation is well suited to use in warm roof constructions: it is robust enough to span the rafters and withstand transferred loads from the roof covering and will resist moisture. Also, its high thermal resistance enables the required U-value to be achieved with a minimum thickness of insulation, which reduces the loads applied to fixings.
