Architectural glass is a type of glass used for a building material. The glass is thicker than windows and is usually toughened and laminated to reinforce it for safety measures and structural support. Even though the glass is so thick, there are times when it can become broken, damaged, or faulty and require repairs. This list goes over some of the various reasons why the glass would need repairs and how to solve it.
Construction damage is caused when construction workers are careless when they are working on the building. Damage can be caused by ladders or equipment placed against the windows, plaster being wiped off the glass, wire lath dragged across the glass, painters trying to remove paint from the glass, masons getting mortar on glass, grout on the glass, welders grinding steel near the glass or welding slag falling on it, and texture contractors getting excess texture on the glass.
Sometimes when the architectural glass is being delivered to the destined site, it will become damaged. This may include scratches, cracks, or other faults that will need to be repaired before installing the glass on the building.
Most people don't realize it, but fog is a huge problem for architectural glass. Water exposure or excess heat can get inside the panes and create a foggy look. There are four different stages of fogging glass:
Foggy: There is a certain threshold saturation point that a window will reach before the moisture inside grows and makes the glass look foggy. The mist may appear and disappear throughout the day in this stage.
River Bedding: Once the saturation point is crossed, it will begin to cause permanent damage to the window. The moisture will run over and over down the window and create the 'river bedding' effect on the glass.
Silica Haze: This is a chemical growth that grows in architectural glass. Even if the window shows no sign of moisture, the silica can be present inside of it. The haze looks like a snowflake pattern running at angles throughout the glass. It can also appear like a white chalk-like haze growing on the glass.
Riverbed and Silica Haze: This stage is the combination of stage two and three together. When the glass has both in it, it is irreversible damage.
There are many other things that cause damage to architectural glass: vandalism, environmental change, cleaning, and manufacturing. All of these causes require that the glass be restored to its original state or repaired. In cases where restoration or repair doesn't work, the entire glass may have to be replaced completely.
