Frame Material Comparison — Thermal Performance & Cost
The frame material is one of the biggest factors in both double glazed windows price and long-term energy savings. Here's how the three main options compare for Melbourne homes:
uPVC Frames
- ✓ Best thermal insulation of all frame types
- ✓ Zero maintenance — no painting or sanding
- ✓ Excellent noise reduction performance
- ✓ 30+ year lifespan, UV-stable
- ✗ Slightly thicker frame profile
Typical cost Melbourne: $2,300–$3,500+
Timber Frames
- ✓ Natural aesthetic, traditional look
- ✓ Good insulation properties
- ✓ Works well in heritage properties
- ✗ Requires regular painting/sealing
- ✗ Can warp with moisture over time
Higher ongoing maintenance cost over time
Aluminium Frames
- ✓ Slimmer, sleek frame profile
- ✓ Durable and low maintenance
- ✓ Wide colour range available
- ✗ Poor insulation unless thermally broken
- ✗ Thermally broken versions add cost
Lower U-value = better insulation performance

Fixed (non-opening) windows are the most affordable, typically from $1,800 installed. Sliding windows are the next most affordable among openable types.
Yes — properly installed double glazing can reduce outside noise by up to 42dB, depending on glass thickness, acoustic specification, and sealing quality.
High-quality uPVC double glazed window systems typically last 20–35 years with minimal maintenance. Unlike timber, uPVC frames do not require painting or re-finishing.
Most standard like-for-like replacements do not require council permits. Exceptions apply if your home has a heritage overlay or if structural changes are involved. All replacement windows must comply with the National Construction Code (NCC).
uPVC frames offer the best insulation and energy efficiency for Australian conditions, with U-values of 1.0–1.4. They deliver the strongest long-term performance and lowest maintenance cost for Melbourne's climate.
