Polyair - Thermo Reflective Products

Bradford Polyair™ is a range of thermo reflective insulation products that reduce radiant heat gain in roofs and walls. The products can be used in a range of residential applications, commercial applications and in sheds.

Polyair Performa XHD

Bradford Polyair Performa

Polyair Performa XHD is a high grade radiant heat barrier and extra heavy duty sarking in one product. It boosts the thermal performance of roofs and walls while improving the comfort and energy efficiency of a home.

Polyair Performa XHD

Polyair Performa XHD is a multi layered thermo reflective insulation and extra heavy duty sarking in one product. Its special antiglare coated foil reflects up to 95% 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

*Ventilated attic space based on incorporating minimum 2x wind driven ventilators such as Edmonds WindMaster 300mm throat ventilator (total aggregate area 0.14m2) in conjunction with Edmonds eave vents of not less than 0.2% of the plan ceiling area. Refer to explanation in the BCA The contribution of Polyair Performa XHD 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 Performa XHD 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.

**Refer to brick cavity alternative solution report for installation requirements.
