Aluminium vs Timber Window Frames: A Comparison for Australian Homes

Australia’s diverse climate, which ranges from tropical and arid to temperate, necessitates careful consideration when choosing window frames. Both aluminium and timber are popular choices, each offering unique benefits and drawbacks.

Aluminium Window Frames


  1. Resilience in Diverse Climates: Aluminium is resistant to corrosion and weathering, making it suitable for coastal regions in Australia where salt can be corrosive, as well as for the arid interiors.
  2. Low Maintenance: Given the intensity of the Australian sun, the low maintenance aspect of aluminium can be an advantage.
  3. Cost-Effective: Generally, aluminium frames can be more affordable than high-quality timber, making them an appealing option for budget-conscious homeowners.
  4. Versatility: Aluminium can be powder-coated in a variety of colours to match the Australian landscape and architectural styles.


  1. Heat Conductivity: Aluminium’s thermal conductivity can be a challenge in both hot and cold Australian climates. However, modern aluminium frames with thermal breaks can improve insulation.
  2. Aesthetics: While versatile, some homeowners may prefer the natural appeal of timber.

Timber Window Frames


  1. Natural Insulation: Timber naturally insulates against the heat and cold, an important consideration for energy efficiency in Australia’s varied climates.
  2. Classic Aesthetics: Timber frames can complement traditional Australian architectural styles, such as Federation or Queenslander homes.
  3. Sustainability: Responsibly sourced timber can be an environmentally friendly option.


  1. Maintenance in Harsh Climates: Timber frames in Australia may require regular upkeep to protect against the harsh sun, humidity, or coastal salt.
  2. Cost: Quality timber frames may come at a premium price.


In Australia, the decision between aluminium and timber window frames hinges on factors such as regional climate, maintenance preferences, budget, and aesthetic desires. Both materials offer unique advantages, and homeowners should weigh these considerations carefully to make a choice that aligns with their needs and the Australian environment.
