Designed by the award-winning architects at Sunpower Design, this unique home achieves an outstanding 7.6-Star energy rating.
Sunpower Director, Mr. Andreas Sederof, says they used Kingspan AIR-CELL Insulbreak 65 to help boost the energy efficiency of the home.
“We wanted a really high thermal rating for the roof, so we specified two layers of Kingspan AIR-CELL Insulbreak 65 - one between the rafters and battens and another between the battens and the roofing - which helped to significantly reduce the cooling loads,” he says.
“It’s the perfect material to use under the copper cladding as it provides a thermal break.”
The roof space was then supplemented at the ceiling level with R6.0 polyester batts.
Aside from thermal performance, non-allergenic characteristics are also very important in selecting insulation materials, according to Mr. Sederof.
“The use of non-irritant insulation materials is important in all our designs, which is why we like to use Kingspan AIR-CELL for reflective insulation and polyester for bulk insulation,” he says.
“The fibre-free nature of Kingspan AIR-CELL also means it’s easily handled and installed by the roofers.”
Other sustainability features of the home include AAC (autoclaved, aerated concrete) blocks, double-glazed windows and doors, a 2 kW solar PV system, FSC-certified jarrah boards, and a 23,000 L underground water tank.
