When Do Australian Standards Require Safety Glass?

This catches more people than any other rule we deal with, almost always when replacing a pane in an older home. The glass that has sat in that door for fifty years would very likely not be permitted today.

Where safety glass is required

Under Australian Standards, safety glass is required in these positions:

• In a door — any glazed panel in a door leaf
• Beside a door — side lights and panels within a defined distance of a door edge
• In a bathroom or wet area — where someone could slip against it
• Below 500mm from floor level — low-level glazing anyone could walk into
• Anything that can be sat on, leaned against or walked into — table tops, shower screens, balustrades

The standard that governs this is AS 1288. The exact thresholds depend on pane size, height and position, so treat the list above as the cases to watch rather than the complete rule. If your panel is near a boundary, tell us where it is going and we will talk it through.

What counts as safety glass

Two kinds qualify, and they behave very differently:

Toughened. Heat treated so the surface is in compression. Several times stronger than ordinary glass of the same thickness, and when it does break it crumbles into small blunt granules rather than shards. It cannot be cut or drilled after treatment.

Laminated. Two or more sheets bonded around a plastic interlayer. It breaks like ordinary glass but the interlayer holds the fragments in place instead of letting them fall. This is why it is used overhead and in balustrades.

Which one to choose depends on the position.

What does not count

This is where the misunderstandings happen. None of these are safety glass:

• Patterned glass — Cathedral, Satinlite, Spotswood. The texture is decorative, not structural.
• Frosted or acid etched glass. Surface treatment does not change how it breaks.
• Wired glass. It is fire-rated, which is a different property entirely.
• Thicker ordinary glass. A 10mm annealed pane is still annealed.

Any of these can be made into safety glass by toughening or laminating. But the frosting or the pattern on its own does nothing.

Why like-for-like replacement is a trap

A 1960s hallway door with an original patterned pane is extremely common in Melbourne. The instinct is to order the same thing again. But the position — in a door — now requires safety glass, and the original almost certainly is not.

Replacing it with another annealed patterned pane puts it back into a position the standard no longer allows. The practical fix is usually a toughened version of the same pattern, or a laminated alternative where the pattern cannot be toughened.

Specify it when you order

Toughening happens after cutting and edgework and cannot be undone or modified. Every dimension, hole and edge finish must be final before the panel goes into the furnace.

So this is not a decision to leave until later. Tell us where the panel is going when you order, and we will tell you what the position requires.

Toughening is available across the clear, low iron, frosted and grey ranges. For positions where laminated is the better answer, see laminated glass.
