This guide compares the benefits of each material to help you make a confident, informed decision.

uPVC Windows: Energy Efficiency Meets Affordability

uPVC (unplasticised polyvinyl chloride) is a low-maintenance, weather-resistant material known for its thermal performance and value.

Key Benefits:

  • Excellent insulation: uPVC frames are non-conductive, making them ideal for energy efficient windows.
  • Noise reduction: Often paired with double glazing for a quieter home.
  • Low maintenance: No need to repaint or treat — uPVC won’t rot, warp or corrode.
  • Cost-effective: More affordable than most aluminium systems.
  • Great for Melbourne homes: Performs well in variable climates and coastal areas.

Best for: Homeowners looking to reduce energy bills, enjoy year-round comfort, and stick to a modest renovation budget.

Aluminium Windows: Slim, Strong, and Stylish

Aluminium is a durable metal that allows for sleek profiles and modern aesthetics. It’s especially popular in architectural and designer builds.

Key Benefits:

  • Slimline frames: Maximise glass area and views.
  • Design flexibility: Great for modern window designs and custom shapes.
  • Strong and durable: Ideal for large windows or high-traffic areas.
  • Low maintenance: Like uPVC, it won’t rust or rot.
  • Suits urban and high-end homes: Often used in contemporary builds.

Best for: Homeowners prioritising a minimalist look or structural strength — especially for large or uniquely shaped windows.
