Glass Balustrade Installation — What You Need to Know
Glass Balustrade Systems
Glass balustrade is used on decks, balconies, stairs, mezzanines, and around pool areas where a railing is required. Unlike pool fencing (which follows AS 1926.1), balustrade is governed by AS 1170.1 for loading requirements and the National Construction Code.
System Types
There are several glass balustrade systems available, each suited to different applications:
Frameless 12mm — Uses 12mm toughened glass with spigot or standoff fixings. Suitable for low-level applications and areas with moderate wind exposure. See our 12mm balustrade range.
Frameless 15mm — Uses 15mm toughened glass for higher loading requirements. Required for many elevated balcony applications. See our 15mm balustrade range.
Channel System — Glass panels sit in an aluminium U-channel fixed to the substrate. Clean look with minimal visible hardware. See our channel balustrade.
BARR System — Aluminium posts with glass infill panels. Good balance of aesthetics and cost. See our BARR balustrade.
Blade System — Slimline aluminium blade posts with glass panels. Modern architectural look. See our Blade balustrade.
Structural Requirements
Glass balustrade must withstand specific loading requirements under AS 1170.1. The minimum requirement for residential balustrade is a horizontal load of 0.75 kN/m applied to the top of the balustrade.
For commercial applications, the loading requirement increases to 1.5 kN/m or higher depending on the use.
The substrate (deck, slab, or structural member) must be capable of supporting the balustrade loads. This is especially important for timber decks, which may need reinforcement.
Height Requirements
The National Construction Code specifies minimum balustrade heights:
Professional Installation
We strongly recommend using a qualified and licensed builder or glazier for glass balustrade installation. Incorrect installation can create safety hazards and may not comply with building codes.
A professional installer will ensure proper load transfer to the structure, correct glass thickness for the span, and compliance with all applicable standards.
