7 star test

Windows and glazed doors are the cornerstone of any effective strategy to meet the 7-Star NatHERS performance requirements for new builds.
 
As compliance with these regulations can often lead to financial strain due to the need for costly energy efficiency upgrades, finding a cost-effective aluminium window and door solution is crucial.

And this is the aim of the game-changing Thermal Star™ range – to provide you with a way to achieve affordable 7-star performance.

 


 

Testing the Thermal Star™ Range

To demonstrate the efficacy of the Thermal Star™ range we set up a test. We compared the performance of single storey and double storey display homes with and without Thermal Star™ 150 Series thermally improved aluminium windows and doors. In every other way the houses were as similar as possible.

All featured:

  • A dark colour scheme.
  • Similar overshadowing.
  • Similar insulation levels.
