Whether you’re a homeowner/renovator or a residential builder, ensuring your home is NatHERS 7-star compliant is essential.

One of the best ways to improve temperature regulation and energy efficiency in your home or new build is to use thermally broken windows and glazed doors.



What Are Thermally Broken Windows?

They’re a type of aluminium window featuring a barrier between the interior and exterior frames. This barrier, typically made from a low-conductive material like polyamide, minimises heat transfer. This creates a ‘split’ frame that prevents heat or cold from travelling through the frame into your home, significantly improving energy efficiency and home comfort.

3 Reasons To Have Thermally Broken Windows In Your Home


1. Improved Thermal Efficiency

The most significant benefit of thermally broken aluminium windows is their energy efficiency. By reducing heat transfer through the window frames, thermally broken frames can help keep your home cooler in the summer and warmer in the winter. This will not only save you money through lower heating and air conditioning usage, but it will also go a long way in helping you achieve 7-star performance for your build.


2. Reduced Condensation

Another benefit of thermally broken windows is that they can help reduce condensation. Condensation occurs when warm, humid air meets a cold surface, like a windowpane. With traditional windows, this can lead to excess moisture build-up, damaging walls, floors, and furnishings. They minimise condensation by reducing the temperature differential between the interior and exterior of the window.

3. Enhanced Noise Reduction

In addition to their energy efficiency and moisture control, thermally broken aluminium windows can help reduce noise pollution. The insulating properties of the barrier between the interior and exterior frames help block out unwanted ambient noise, especially when combined with double glazing, to create a quieter and more peaceful living environment.
