Energy-efficient windows for SA’s climate
Energy-efficient windows combine double glazing, low-e glass, gas-filled cavities and insulating frames to cut heat gain in summer and heat loss in winter. Clearfox Windows specifies and installs them across Adelaide metro and the Hills; premium double-glazed uPVC runs about $2,500–$7,500 per opening fitted. Request a quote for a free on-site measure.
Low-emissivity (low-e) glass, argon-filled cavities, thermally-broken aluminium frames, premium uPVC systems — the technology stack that reduces heating and cooling losses through your windows.
What we do
Where products carry published performance figures (for example a WERS rating), we use them to specify the windows your project needs. Whole-window U-values range from roughly 6 W/m²K or more for single-glazed aluminium down to around 2 W/m²K or lower for well-specified double-glazed uPVC or thermally-broken systems.

Frequently asked questions
What U-value should I specify?
For new builds, the required window performance comes from the project’s energy assessment (NatHERS or the NCC deemed-to-satisfy pathway), so ask your energy assessor or builder for the target. Lower U-values mean less heat transfer; where products publish U-values, we put them on the quote.
Does the orientation of the window matter?
Yes. North-facing windows should target high SHGC (solar heat gain coefficient) for winter warmth; west-facing should target low SHGC to block summer afternoon heat. We balance the spec per opening.
How much do energy-efficient windows cost in Adelaide?
As a typical guide for Adelaide homes: $2,500–$7,500 per opening fitted for premium double-glazed uPVC systems. Low-e double glazing costs more than standard double glazing, and the difference is itemised on your quote. Your written quote after the on-site measure sets out the exact price, line by line.
