Operable Windows on Two-Story Homes

When you have operable windows in your home, especially on upper levels, safety is a crucial consideration.

At Red Dog Property Inspections, we occasionally identify issues regarding window openings in residential properties.

We often observe that some operable windows could open wider than the current building regulation requirement of a 125 mm opening sphere.

In this blog, we will discuss the implications of non-compliant operable windows, the regulations set forth by the National Construction Code, and the best practices for ensuring safety.

Understanding the Regulations

According to the National Construction Code (NCC), there are specific guidelines for windows, especially in upper-story levels. The rules state:
• No Specific Requirements for Openings Below 2 m: If the floor level below an operable window is less than 2 meters, the NCC does not impose specific requirements.
• Requirements for Openings Above 2 m: If an operable window is located at a height where a fall could occur—from floor to ground of 2 meters or greater—any openings within 1700 mm of the floor must be secured with safety devices or screens.

Failure to comply with these regulations poses significant safety risks, as individuals could potentially fall from the upper story, resulting in serious injuries or even fatalities.

Recommended Safety Measures

To address the risk associated with operable windows, consider the following safety measures:\

1. Install Restrictors: Ensure that operable windows have devices that restrict the size of the opening to comply with the 125 mm requirement. This can help prevent accidental falls while still allowing for ventilation.\
2. Use Barrier Screens: For windows that pose a fall hazard, installing secure barrier screens can provide an additional layer of protection without sacrificing access to fresh air.\
3. Consult Professionals: Engage a registered builder or window supplier to assess your windows and ensure compliance with current building standards and regulations. They can recommend suitable hardware options such as short chain winders and other safety devices to enhance safety.\
4. Regular Maintenance Checks: Regularly inspect the hardware and functionality of your operable windows. Ensure that all safety devices and screens are functioning properly and in good condition.

Conclusion

The safety of your home should always be a top priority, especially when it comes to operable windows on upper levels. At Red Dog Property Inspections, we urge property owners to remain vigilant about compliance with building regulations to prevent potential accidents.
