Heat or chemical tempering?
|
The strength and heat resistance of glass can be increased through a heat treatment or by a chemical process. Discover the differences, benefits and performance of both types of procedures and glasses with us.

 Chemical strengthening is a process in which glass is fortified using an ion-exchange method. This process is used when extremely thin glass is needed and increased strength is required. As a result this process offers an increased surface compression that strengthens the glass without creating distortions, and the glass surface is rendered harder and more resistant to scratching. With chemical-tempered glass there is no risk of spontaneous breakage. Heat-treated glass is subjected to a special process in which it is heated to about 680°C and then rapidly cooled. This type of glass can be classified as either heat-strengthened glass or fully-tempered glass depending on the measurements of edge or residual compression. Given that it can satisfy diverse building safety code requirements, it is used in interior applications such as shower doors, stairway balustrades, glass passages, furniture, ovens, fireplace screens, etc. Read more information on the selected links.
