Quinn Therm QW Cavity Wall PIR

Quinn Therm QW Cavity Wall PIR Insulation  is a high performance, fibre free board, with a rigid thermoset insulation core and faced on both sides with a low emissivity composite foil facing, for use in partial fill cavity wall applications. 

The low emissivity foil facings increases the thermal resistance of the residual cavity and reducing the overall U-value of the wall. 

The good dimensional tolerances of the QW Cavity Wall PIR Insulation board enabling it to be tightly butted to form a continuous layer of insulation.  

Available with profiled T & G edges aiding installation and ensuring continuity of insulation across the joint. 


QW-Cavity Wall board sizes are co-ordinated with standard wall tie spacings
Tongue and groove edging for continuity of insulation across joints
Zero ozone depletion potential (zero ODP) and low global warming potential (GWP)
Achieves an A+ rating when compared to the BRE Green Guide
