Design & Build Quality (Sydney-proof)
Materials & construction
Modern aluminium sliding doors offer slim sightlines, durable powder-coat, and sealed frames. Look for systems tested to AS 2047 with quality rollers and stiffer meeting stiles for larger openings. :contentReference[oaicite:2]{index=2}
Coastal suburbs? Add marine-grade finishes, stainless fixings, and diligent track cleaning (salt + grit is the enemy).
Ergonomics & durability
- Low-friction rollers and level tracks = easy glide.
- Laminated or DG units lift acoustic/thermal comfort vs single glaze.
- Serviceability: rollers & locks are replaceable; tracks can be capped.

Pros & Cons
What we loved
- Best value per metre for large openings.
- Slim frames, screen friendly, easy operation.
- Upgradable glazing for acoustic & thermal gains.
Areas for improvement
- Tracks collect grit—needs regular cleaning.
- Very wide spans may require heavier frames or lift-slide hardware.

Purchase Recommendations
Best for
- Patios/courtyards needing 2–4 m clear openings.
- Homes wanting sliding doors external with flyscreens.

Skip if

Alternatives to consider
- Bifold doors: bigger opening feel; higher price & maintenance.
- Lift-and-slide: premium sealing/operation; highest price bracket. :contentReference[oaicite:10]{index=10}
