Top Energy Efficient Windows Options to Choose
With rising energy costs and increasingly strict building standards, more Australians are looking for smarter ways to keep their homes and businesses comfortable year-round. If you’re wondering which windows are most energy efficient, the good news is: you’ve got options – and they’re more advanced than ever.
From classic double glazing to high-tech smart glass, here’s a breakdown of the best energy efficient windows to consider, plus how they can help you save money, reduce your environmental footprint, and boost long-term property value.
Why Energy Efficiency in Windows Matters
Before diving into the best window styles, it’s worth revisiting the benefits of energy efficient windows. From reducing heat loss in winter and limiting heat gain in summer to blocking out noise and protecting interiors from UV damage, energy-efficient windows offer year-round advantages.
Upgrading is one of the most effective changes you can make to improve overall comfort, sustainability, and long-term savings in your space.
1. Awning Windows
Double glazed awning windows are hinged at the top and open from the bottom, making them ideal for maintaining airflow while keeping out rain. Their design works well in wet or humid environments, and when closed, they seal tightly to improve insulation—an excellent choice for energy-conscious homes.
2. Casement Windows
Double glazed casement windows are side-hinged and open outward, offering great airflow and a clean, unobstructed view. They create a strong, airtight seal when closed, making them a popular option for those prioritising double glazed windows and energy performance.
3. Tilt & Turn Windows
Tilt & turn windows provide flexible functionality. They tilt inward for gentle ventilation or swing open like a door for maximum airflow and easy cleaning. Perfect for both residential windows in Sydney and modern interiors, they pair well with double glazed windows or triple glazed windows for even greater energy efficiency.
4. Lift and Slide uPVC Doors
For homes with large openings or scenic views, lift and slide uPVC doors offer impressive performance without sacrificing style. These doors glide smoothly and seal tightly when closed, reducing energy loss through wide entry points.
Pair them with high-performance glazing for year-round insulation.
5. UPVC Bifold Doors
UPVC bifold doors (or folding PVC doors) fold neatly to the side, allowing for wide open access to outdoor spaces. Newer models are thermally broken and double glazed, making them far more energy efficient than older designs.
These are ideal for modern renovations where flexibility meets performance.
6. Double Glazed French Doors
Double glazed French doors add charm and character to your home, but now they can also offer excellent energy performance. Combined with uPVC frames and quality seals, these classic doors keep warm air in during winter and hot air out in summer.

7. Smart Sliding Doors
Tech-savvy homeowners are turning to smart sliding doors to boost convenience and efficiency. With options like automated opening, smart tinting, and enhanced sealing systems, smart glass sliding doors provide modern energy-saving functionality alongside style.
They’re especially useful for reducing solar heat gain in sun-exposed areas of the home.

Frequently Asked Questions
Which windows are most energy efficient for Australian homes?
The most energy efficient windows often feature double or triple glazing, insulated uPVC or thermally broken aluminium frames, and airtight sealing. Options like triple glazed windows, casement, and awning windows perform exceptionally well in Australia’s varied climate.
How do I know if a window qualifies for the 7-star rating?
Windows that support a 7-star NatHERS rating are designed with high thermal insulation, low-emissivity (low-e) glass, and tight sealing to minimise air leakage. To confirm a window’s energy performance, check its rating through the Window Energy Rating Scheme (WERS), which provides independent assessments based on heating and cooling efficiency. Look for products with strong WERS ratings that align with your home’s energy goals.
Can energy efficient windows help reduce noise?
Absolutely. Multi-pane glazing and tightly sealed frames also provide acoustic insulation. Many customers install these as acoustic windows to enjoy a quieter, more peaceful home.
