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 metal deck an AVCL should be laid over the deck with 150mm sealed laps turned up at any vertical upstand. The AVCL should consist of a minimum 1000 guage (250um) polyethylene sheet.
