Many factors contribute to the energy efficiency of a home, from property size and geography through to products and materials. When it comes to products, windows can be key in achieving higher ratings of energy efficiency performance.
Broadly, the general idea of energy efficiency is to achieve something with the least amount of energy usage possible. In relation to windows, energy efficiency usually refers to a product’s ability to maximise the conditions you create in your home through heating or cooling, while minimising energy expenditure.
With a higher energy efficiency rating, you can spend less time and energy maintaining a pleasant temperature in your home. The higher your rating, the better your windows’ ability to ‘trap’ the hot or cold air that comes from heaters or air conditioning systems. The more air your windows trap, the less you need to run your systems. And therefore, the less energy you use (and buy!).
There are multiple degrees of energy efficiency that different windows can achieve. The energy efficiency performance of windows can also be affected by other factors, including climate, building materials, and where your home is located.
Wherever you live throughout Australia—whether it’s a cooler climate or a warmer climate–your choice of windows can significantly impact upon your home’s energy efficiency performance.
Here’s how buildings gain and lose their heat through common household materials:
|How heat loss can occur in buildings||How heat can accumulate in buildings|
|In cooler climates, buildings lose heat through materials in roughly the following proportions:||In warmer climates, buildings gain heat through materials in roughly the following proportions:|
|Walls: 14%||Walls: 8%|
|Floor: 18%||Floor: 0%|
|Roof: 19%||Roof: 5%|
|Glass / Windows: 49%||Glass: 87%|

With our inline reveal, the timber reveal sits flush with the aluminium frame. In many competing window products, the timber reveal is offset. By sitting flush, the inline reveal prevents heat passing through the aluminum, promoting improved energy efficiency.
Stay warmer in winter and cooler in summer
Thanks to the effects of timber—a natural insulator—the inline reveal prevents heat loss through the aluminium frame. Your home’s more likely to retain the effects of heating or air conditioning, keeping you comfortable and saving you money on your energy bills.
Enjoy more natural light and a clearer view
The inline reveal promotes a larger glass area than other products with an offset reveal of the same stud opening size. With more glass, you’ll enjoy more natural light and a cleaner aesthetic for your windows.

Savings are in comparison to using 3 mm clear glass and may vary depending on actual operating conditions. Source AGWA.
Double glazed windows can help you save on power bills and consume less energy overall, depending on certain factors in your home. Learn about double glazing, why it’s effective, and why you should consider upgrading today.
When it comes to windows, energy efficiency is a scale, not a ‘yes-or-no’ concept.
There are multiple degrees of energy efficiency that different windows can achieve. The energy efficiency performance of windows can also be affected by other factors, including the climate in your region of the country, building materials, and where your home is located.
