When it comes to the safe installation of glass in buildings, the National Building Regulations in South Africa have very specific requirements.
These regulations ensure that architects and designers select the right type of glass for windows, skylights panels, partitioning and doors within a building which are suitable for their applications.
These specifications ensure that the building and its occupants are protected from potential injury related to the incorrect installation of glass.
The regulations ensure that window glazing in any building is done correctly and is secure, durable and fixed in such a way that:
The SANS 10400 specifies where safety glass is required and where standard or annealed glass is acceptable.
Glazing must comply with SANS 613 to ensure that it can withstand impact and wind loads according to SANS 10400-B, which addresses the correct structural design of a building.
Furthermore, where glass may not be noticed by people approaching it, there must be a sign or marking which serves as a warning and is clearly visible.
In addition, these standards also specify where frameless glass may and may not be installed.
Standard glass may be used in a door pane that is not larger than one square meter. However, this glass must be a minimum of 6mm thick.
For areas that are larger than one square meter, safety glass must be used.
In situations where windows are not protected by barriers, the window sill must be at least 300mm above the floor.
When a window reaches the floor, and there is no protective barrier in front of it, it poses a serious safety risk for anyone approaching it.
In such cases, it’s required that safety glass is used for an area of at least 800mm above the floor.
In addition, safety glass must be used in shower cubicles, bath enclosures, shop windows or fronts that are larger than one square meter.
Lastly, safety glass must also be used for balustrades or walls leading to ramps or stairways where the glass used is less than 1.8 meters above the landing.
The National Building Regulations of South Africa have been put into place to ensure utmost safety when designing and constructing buildings.
