Glass Balustrade vs Aluminium — Pros, Cons and Costs
Barrier Hub Team22 March 2026
The Balustrade Decision
When building or renovating a deck, balcony, or staircase, the balustrade system you choose has a major impact on the look, feel, and value of the space. Glass and aluminium are the two most popular options for Australian homes.
Glass Balustrade
Glass balustrade uses toughened safety glass panels as the barrier element. Systems range from frameless (glass fixed with spigots or in channels) to semi-frameless (glass held between aluminium posts).
Pros
Unobstructed views — ideal for properties with water views, gardens, or scenic outlooks
Aluminium balustrade uses aluminium posts with infill options including aluminium slats, wire, or a combination of materials.
Pros
Lower cost — the most affordable balustrade option
Lightweight — minimal additional structural load
Low maintenance — powder-coated aluminium is weather resistant
DIY-friendly — many systems designed for homeowner installation
Colour options — wide range of powder coat colours
Cons
Obstructed views — slats or wire infill break the line of sight
Limited wind protection — open designs don't block wind
Visual impact — can look dated or suburban compared to glass
Lower resale value — less premium than glass options
Cost Comparison
For a typical 10-metre deck balustrade with one return:
| System | Materials Cost (est.) |
|--------|----------------------|
| Frameless Glass (12mm) | $2,500 - $3,500 |
| Channel Glass | $2,200 - $3,000 |
