Why Thermally Broken Aluminium Frames Are Ideal for Office Builds

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.
