Regular glass, also known as annealed glass or float glass is the traditional form of glass that many of us know. This glass shatters when it breaks into shards that can be sharp and harmful. Regular glass is popular for use in windows in residential homes and often doors as well. It is widely used as it is quick, easy and cheaper to make, and it can be reworked. Regular glass can be cut, reshaped, have the edges polished and holes drilled, without breaking or shattering the glass, which gives it more flexibility and range of use.
Where You’ll Find Regular Glass
Regular glass is frequently used in windows where the risk of the window breaking and causing considerable damage is lower. This includes in double and triple glazed windows where 2 or 3 panes of regular glass are separated with a spacer and interspersed with a gas or air in order to provide better insulation properties. It can also be used in mirrors, and it could be used in various setting in older homes or where glasswork was not done by a licensed professional. (Note: These applications of regular glass could be unsafe.
