Quinn Therm QL Kraft PIR

Quinn Therm QL Kraft PIR Insulation is a high performance, fibre free insulated board, with a kraft paper facing on one side and plasterboard bonded to the other side. 

Quinn Therm QL Kraft PIR Insulation is ideally suited to be used under rafters to reduce the overall heat loss through the roof and eliminate thermal bridging through the rafters.

With the additional benefit of its paper facer, Quinn Therm QL Kraft PIR Insulation is also suitable for use in dry-lining applications fixed in place using dot-and-dab adhesive or mechanical fixings.
