Upstairs bedroom windows that open too far
The 125mm rule for first floor bedroom windows, and why we check it at fixing stage.
In short: Several first floor bedroom windows on a Cobbitty build had no opening restriction, a child safety requirement in the National Construction Code.
The finding
At a Cobbitty fixing inspection, first floor bedroom windows had no device limiting the opening to 125mm. It was recorded as a major defect and safety hazard.
What the rule is for
The requirement exists to stop young children falling from upper floor bedroom windows. Where the fall height triggers it, the opening must be restricted or the window protected by a screen.
Why it gets missed
Windows arrive from the supplier with or without restrictors, and it is easy for the item to fall between the window supplier and the builder.
How it is fixed
Fitting a compliant restrictor or screen is quick. The important part is that it cannot be easily overridden by a child.
When to check
Fixing stage is ideal, because windows are in and there is time to order hardware before handover.
