Our Story
Astral Windows was developed by Supaglass, a Canberra-based company with a proud history in architectural glazing and aluminium systems. Since 2011, we’ve supported builders, architects, and homeowners with reliable, high-quality solutions.
As Australia’s energy standards evolved, so did the need for high-performance, affordable systems that didn’t compromise on design. We saw the gap—and filled it with Astral. Every profile in the Astral range is made using our own proprietary dies and has been independently tested to meet AS2047 compliance, ensuring full control over quality, performance, and compatibility with Australian conditions.
With Astral, you don’t have to choose between performance, style, and value—you get it all, right from the start.
