SAFETY GLASS – COMMON MISTAKES
The most common variations are still due to safety glazing because there are so many places it can go awry.
The need for safety glass should be checked for at least three times. Once at sales, once at survey and finally at installation. Below are the top six most common mistakes made:
- Next to doors – The surveyor may not note on the survey that a window next to a door needs safety glass because the factory will pick up it is a door combination. However during order processing doors and windows sometimes get spilt up and that flag window is suddenly just a window…
- Bathrooms – Any bath or shower tray below the window becomes the finished floor level – so measure from inside that not from the floor. Also, if the window change is part of a refurbishment of a bathroom ask if a bath or shower will be under the window. Remember it is considered good practice to fit safety glass in bathrooms even if the windows are outside critical locations.
- Outside floor level – The measurement of 800mm from floor level or 1500mm when within 300mm of a door is taken from inside and outside. If the glass is below these levels on either side then it is critical and needs to be safety glass. Cellar windows are commonly missed as they are at head height inside but ankle height outside.
- Damaged units – Scratched and damaged units are spotted by the fitter and sizes for a replacement called in. A new unit is made but the safety aspect has been missed and annealed glass is installed in a critical area.
- Units the same size – Often there are two units that are the same size but one is safety glass and the other isn’t. Its easy to switch them by mistake. Some IGU manufactures are trying to combat this using different coloured tape or labels for their toughened units.
- Window seats – Any fixed furniture in front of a window will be considered the floor level so when surveying watch for these and call up the appropriate glass.
