Bradford Polyair Performa

Polyair Performa is a high grade radiant heat barrier that can boost the thermal performance of roofs and walls , improving the comfort and energy efficiency of a structure.

Polyair Performa 1

Polyair Performa is a multi layered thermo reflective insulation product. Its special antiglare coated foil reflects up to 91% of the sun’s radiant heat while the foam inner core and inward facing foil reduces heat transfer through the product.

Total R-Value Assumptions

The contribution of Polyair to a Total R-Value depends on the installation and environmental conditions. The Total R-Value will be reduced in the event of the accumulation of dust on upward facing surfaces and in those cavities that are ventilated. Thermal calculations are based on Australian parameters and in accordance with AS/NZS 4859.1:2002/Amdt.1. The contribution of Polyair towards the Total R-Value depends on installation and environmental conditions. For upward facing surfaces of horizontal or sloping reflective insulation in non-vented cavities where no special precautions for prevention of dust ingress have been included, the Total R-Value is calculated based on an emittance for the case of dust cover in accordance with AS/NZS4859.1 Paragraph K3.2(a)(ii), unless otherwise stated. For calculation purposes, the air gaps are assumed as still parallel air gaps unless otherwise stated and the membrane continuous.
