Quinn Therm QF PIR Insulation Board

Quinn Therm QW-STFI Steel/Timber Frame Insulation

Foil faced rigid Polyisocyanurate (PIR) insulation, for external cavity walls of conventional timber and steel framed dwellings with a masonry outer leaf. Height restrictions apply in some cases. QW -STFI may be installed between structural studs. Also, used with insulated dry lining systems and as insulated sheathing or used as part of a system incorporating any combination of these options.

QW-STFI has been tested to BS EN 1365-1:2012 and BS 476-21:1987 for use with structural steel/timber studs, where a fire resistance of 30 minutes is required. In steel stud construction it has 60 minutes fire resistance.

The wall insulation will be QW-STFI manufactured by Quinn Therm Ltd, to BS EN 13165-1:2012.
Comprising a rigid Polyisocyanate (PIR) core with low emissivity trilaminate aluminium foil facings.
Low thermal conductivity, minimising the thickness required to achieve the design U-value.
Zero ozone depletion potential (zero ODP) and low global warming potential (GWP)
Achieves an A+ rating when compared to the BRE Green Guide.
To be installed in accordance with the instructions of Quinn Therm Ltd. and conditions set out in the BBA Certificate 07/4444.
