Aluminium vs Timber Windows: What's Best for South East Queensland Homes?

If you're building or renovating in South East Queensland, one of the biggest decisions you'll face is window frame material. Timber windows have a certain old-world charm — they're the stuff of classic Queenslanders and Federation cottages. But when you stack them up against modern aluminium in the context of Brisbane, the Gold Coast, and the Sunshine Coast, the case for timber starts to look shaky pretty quickly.

Here's an honest comparison of both materials, and why aluminium consistently comes out on top for SEQ conditions.

The Climate Challenge

South East Queensland is a beautiful but demanding environment for building materials. Summers bring intense UV radiation, high humidity, and heavy rainfall. Coastal suburbs add salt air into the mix. Winters are mild but the temperature swings between seasons still cause materials to expand and contract over time.

Timber is a natural product — and nature doesn't love it back in these conditions.

Timber: The Charm, the Problems

There's no denying timber windows have visual appeal. They suit the heritage character of older Queensland homes and can be painted or stained to suit almost any style. But maintaining that appeal in SEQ's climate comes at a significant cost — in both time and money.

The key issues with timber in SEQ:

• Moisture damage — Queensland's humidity and heavy summer rain causes timber to swell, warp, and eventually rot if not meticulously maintained. Even hardwood timbers aren't immune over the long term.
• UV degradation — Constant sun exposure bleaches and dries out timber, causing paint to peel and crack, which lets moisture in.
• Termite risk — SEQ is one of the highest-risk areas in Australia for termite activity. Timber window frames offer an easy entry point.
• Ongoing maintenance — Timber windows need sanding, repainting, or re-oiling every few years. That's real time and real money on a recurring basis.
• Reduced energy performance — Unsealed or warped timber frames allow draughts and reduce the efficiency of your glazing investment.

Aluminium: Built for Australian Conditions

Modern aluminium windows address every one of those pain points — and then some. The Carinya aluminium window range, supplied by Window & Door Supplies, is designed and tested specifically to meet Australian standards and perform in conditions exactly like SEQ's.

Why aluminium wins in South East Queensland:

• Corrosion and moisture resistant — Aluminium doesn't rot, swell, or warp. It holds its shape and seal year after year, regardless of humidity or rainfall.
• Salt air rated — Critical for homes within a few kilometres of the coast. Aluminium frames handle the coastal environment with ease; timber does not.
• Termite proof — No organic material means no termite risk. Full stop.
• Virtually maintenance free — An occasional wipe-down is all that's required. No painting, no sanding, no annual upkeep costs.
• Slim sightlines — Modern aluminium profiles are sleek and stylish. The Carinya range is available in Pearl White, Custom Black, and a range of custom colours — contemporary options that suit new builds and renovations alike.
• Superior glazing compatibility — Aluminium frames pair perfectly with performance glass options including Low-E glass, grey tint, and double glazing — all available through WDS — to reduce solar heat gain and keep your home cooler in summer.
