Newell Roofing Products supply a fibre free board that is a high performance flat roof insulation called Quinn Therm QRFR-FRR PIR. This flat roof insulation has a low emmisivity composite foil facing on both sides with a rigid thermoset insulation core.
QuinnTherm QRFR-FRR PIR insulation boards have low thermal conductivity, therefore the thickness required to achieve the design U-Value is minimised.
These flat roof insulation boards supplied by Newell Roofing Products are compatible with concrete, timber and metal deck constructions.
Quinn Therm QRFR-FRR PIR Insulation boards are ideal for use in new build and refurbishment projects where the warm flat roof is covered with a mechanically fixed single ply membrane.
When installing Quinn Therm QRFR insulation boards supplied by Newell Roofing Products to a timber deck an AVCL should be laid over the deck with 150mm sealed laps turned up at any vertical upstand. The AVCL should consist of minimum 1000 gauge (250um) polyethylene sheet.
