Australians love to bring the outdoors in. This can mean plenty of glazing, floor-to-ceiling windows and glass sliding doors. Achieving this whilst also meeting a 7 Star energy efficient rating has become harder and more expensive–but there are solutions.
With Thermotek window and door systems you can lift a home’s energy efficiency rating while enhancing design. The result is a more liveable and comfortable home that your clients will love–and keep energy assessors happy.
But first, key glazing considerations under NCC 2022:
- Performance glass is now standard as windows can have the most significant impact on energy efficiency.
- Design trends such as floor-to-ceiling windows, large voids, and ample glazing can impede a project’s ability to meet 7 Stars at a reasonable cost.
- Windows can make up about 90% of a home’s heat gain and 50% of a home’s heat loss.
- The design and orientation of living areas is now key–it is most energy-efficient to have windows facing north.
- Low e-glass is about keeping heat out (cooling). Double and triple glazing is about keeping heat in.
Thermotek has been at the forefront of energy-efficient solutions with their German engineered, Australian-made uPVC (unplasticised polyvinyl chloride) window and door systems.
The superior thermal efficiency of uPVC frames limit the transfer of heat to reduce the cost of heating and cooling. Combined with double or triple glazing, and leading construction techniques, Thermotek uPVC windows and doors make a significant contribution to a home’s energy rating.
With Thermotek products it is easier to build to 7 Stars without comprising design. You can still create homes with large window and door designs that bring the outdoors in–just how Australians love to live.

Make 7 Stars work for you
- Understanding the Deem to Satisfy via natHERS software can be a low cost and effective path to compliance.
- Form a strong relationship with your local energy assessor. You and your owner/designer can benefit from guidance to meet new 7 Star requirements.
- Engage assessor early during concept design to avoid expensive solutions.
- Invest in educating the homeowner about the premiums that may be incurred to achieve designs which aren’t efficient.
