Home/uPVC vs aluminium/Thermally broken aluminium
Thermally broken aluminium window suppliers by state
A thermally broken aluminium frame has a polyamide strip between its inside and outside sections, so the frame conducts less heat than plain aluminium. This page lists the Australian system suppliers with a thermally broken range and the businesses that make, sell or import these windows, state by state. Being listed isn't a recommendation.

How we built this list: each business is included only if its own website says it supplies thermally broken aluminium windows (checked 1 Oct 2026). Multi-state manufacturers appear under every state where we found a branch or showroom. "Not stated" means the business doesn't name the system it uses. Types: "Makes windows" = fabricates in its own factory; "Sells & installs" = sells and fits windows made by someone else; "Imports finished windows" = windows made overseas. A thermal break alone doesn't make a window efficient: ask for the WERS rating of the exact frame and glass in your quote.
