Tempered Glass

Tempered glass is necessary in situations where safety glazing is required by building codes or toughened glass is needed for high load applications.

As an SGCC Certified Fabricator, CLG provides high quality tempered glass that can be made in nearly any configuration. More importantly our process capabilities allow for the quick delivery and short lead times demanded by today’s custom design market.

In the tempering process, glass is heated to approximately 1200° F (650° C) and then rapidly cooled with air. This process locks the outer surface of the glass in compression which dramatically increases the glass strength.

When fully tempered this glass is approximately four times stronger than a piece of annealed glass. More importantly, when tempered breaks it dissociates into small pieces which is considered a break-safe pattern. CLG’s tempered glass meets important safety codes, including ANSI Z-97.1-2009 and CPSC 16CFR 1201 categories I and II.
