Aluminium is the most common window frame material in modern Australian homes and commercial buildings. It combines strength, slim design, and low maintenance with broad design flexibility.
Key Features
- Durable & Lightweight: Strong enough for large panes and sliding systems, yet light for easy installation.
- Low Maintenance: Won’t warp, rot, or swell. Only needs occasional cleaning.
- Design Flexibility: Slim frames maximise glass area; powder coating allows extensive colour and finish options.
- Coastal Ready: With marine-grade or anodised finishes, aluminium resists salt air and harsh climates.
- Energy Efficiency: Standard aluminium conducts heat and cold, but thermally broken systems (with insulated barriers in the frame) greatly improve performance and comply with higher energy ratings under the NCC.
Pros
- Long lifespan with minimal upkeep.
- Slim, modern profiles enhance natural light and views.
- Strong enough for wide openings (sliding, bi-fold, stacking doors).
- Widely available across Australia, with competitive pricing.
Cons
- Standard aluminium frames can reduce thermal performance without thermal breaks.
- Can corrode near the coast if not correctly treated/coated.
- Conductivity means glass choice (double glazing, low-E) is critical for efficiency.
Best For
- Contemporary homes with large glass areas.
- Renovations where durability and style are priorities.
- Coastal builds using marine-grade finishes.
