Benefits of Thermally Broken Aluminium Frames in Office Buildings

Thermal Breaks: The Gap That Changes Everything

Aluminium is great. It’s strong, sleek, recyclable, and doesn’t warp in the sun. But left to its own devices? It’s also a highly efficient thermal conductor. Which, in an office building, can mean unwanted heat streaming in through your perfectly framed windows.

Enter: thermally broken frames — a small change with serious upside.


How It Works

A thermal break is just what it sounds like: a non-conductive material inserted between the inner and outer aluminium sections of a window frame. This stops heat (or cold) from moving through the metal — creating a barrier that keeps your interior climate steady.

No more metal frames radiating heat like a barbecue plate on a summer afternoon.

Why It Matters in Offices

Office buildings live and die by thermal comfort. Whether it’s a CBD tower or a business park in the burbs, these projects need to:

  • Meet energy efficiency targets

  • Control internal temperatures without overloading HVAC

  • Provide comfort for workers without complaints about hot desks by the window

Thermally broken aluminium frames make it easier to:

  • Hit U-value targets under NCC

  • Reduce energy bills

  • Support Green Star or NABERS ambitions

  • Create façade systems that perform year-round

Hunter Windows Has You Covered

We manufacture and supply a full suite of commercial-grade thermally broken systems, engineered to:

  • Work with double or triple glazing

  • Meet compliance specs for commercial and high-rise projects

  • Support WERS and energy modelling with accurate data

Need to meet a tight Section J report? Designing a facade that balances glass area with insulation? Or just want consistent comfort across every floor, all year round?

Thermal breaks may be invisible. But you’ll feel the difference — and so will your client’s energy assessor.

Darby Plaza

When EJE Architecture put forward an inspired façade for the GWH Darby Plaza project, Hunter Windows was tasked with making it a reality.

When EJE Architecture put forward an inspired façade design for the GWH Darby Plaza project, Hunter Windows was tasked with bringing it to life.
The challenge involved merging traditional strip windows with a glass curtain wall system—two typically incompatible systems—while following the building’s curved exterior form.

To achieve the desired seamless aesthetic, Hunter Windows developed a custom cast-in bracket system supporting glazed spandrels that appeared as continuous glass from the outside while functioning as balustrades inside. The result met all thermal, acoustic, and fire-rating requirements while maintaining the clean, contemporary look of a curtain wall.

The combination of the precast panelling, large glazed areas, and unique aluminium decorative panels gives Darby Plaza its standout architectural character—a striking addition to Newcastle’s evolving skyline.
