Door and Window Energy Ratings


Bathurst Glass & Window's products are BASIX compliant and have been thoroughly tested by a NatHERS-approved Certifier.

Energy efficient windows and doors will help make your home more comfortable, reduce your energy costs and help to create a brighter, cleaner and healthier environment.

Our products have undergone thorough testing across the window and door ranges through a NatHERS approved Certified AFRC (Australian Fenestration Rating Council) Simulator. We can customise a solution to meet your energy requirements.

It is important to understand that heat energy can be transferred into or out of your home in two ways - Conduction and Radiation. The energy efficiency of a window system is expressed in terms of how well the window insulates against both.

Conduction

Thermal conductivity (the ability of a material to conduct heat) is measured in U-value.

U-value is a measure of the flow of non-solar heat through a window system that includes the frame, glass, seals and any spacers. The lower the U-value, the better a window’s resistance and the better it is at insulating.

Radiation

SHGC (Solar Heat Gain Coefficient) indicates how much sunlight, or solar radiation, comes through your window as heat. It’s expressed as a number between 0 and 1.

Where windows face west and catch the summer sun, you want a low SHGC number to reduce the amount of heat being absorbed into the rooms. The opposite is true for winter months, where solar passive heating can be used to improve the energy efficiency of a home. Read more about window orientation at yourhome.gov.au
