PIR (polyisocyanurate) insulation for creating warm pitched roofs by insulating between and below the rafters. Insulating an existing pitched roof at rafter line - to create what is usually known as a warm roof - is an ideal way of increasing the usable space within the building without having to extend the structure. In projects where the loft space is being upgraded without removing the roof covering the insulation should be installed either in one layer between the rafters or in two layers, one between the rafters and the other fixed to the underside of the rafters (installing the insulation wholly between the rafters will in most cases result in insufficient headroom). QUINN-therm QR rigid insulation is well suited to use in warm roof constructions: it is robust enough to span the rafters and will resist moisture. Also, its high thermal resistance enables the required U-value to be achieved with a minimum thickness of insulation, which minimises the loss of headroom within the loft space.
