Tempered glass is regularly used for windows in both automotive and residential applications because it is generally tougher and safer than regular glass. Each type of glass has its own strengths that make it particularly suited for a certain type of window.

Jeff and Mark of your residential division just left my home after spending two days replacing several storm damaged windows. This is possible because during the annealing process the glass is cooled down slowly, which makes the glass much stronger. It is heat-treated safety glass with a minimum surface compression of 10,000 psi or a minimum edge compression of 9,700 psi. Although glass is used for all kinds of windows, not all types of glass are the same. Understanding the different types of glass available can help you make the best decision for your next window replacement project. Shatter Dynamics A significant difference between annealed and tempered glass is the level of durability provided. Tempered glass has smooth edges . It is used in situations where there is a high probability that it could come into contact with other objects or it’s used in structures where a more robust type of glass is required. Thanks for sending these gentlemen to do our installation. Appropriate Use Standard glass breaks into large, irregular shaped shards.

These come in different designs, form factors, and materials, but they typically help mitigate any drop damage. On the other hand, untempered glass is allowed to cool slowly and, therefore, will react to breakage differently. Float glass manufacturers create low-iron glass, also known as extra-clear glass or optically clear glass, by reducing the amount of iron in the molten glass formula.
