Tempered glass (often referred to as “toughened” or “fully tempered” glass) is heat-treated & cooled to yield a surface compression of 10,000 psi or a minimum edge compression of 9,700 psi. The surface of tempered glass is approximately five times stronger than the surface of raw annealed (often referred to as plate glass) of the same thickness.
When broken, tempered glass shatters into small, relatively harmless pieces that greatly reduces the risk of serious injury.
At CVTG, all of our tempered glass meets the requirements for ANSI Z97.1 and/or CPSC 16 CFR 1201, and the Economic Comission of Europe (ECE). Tempered Glass is almost always labeled with a “safety” logo identifying the fabricator, glass type, and the standard it meets.
CVTG is SGCC (Building Code), DOT (Department of Transportation) and ECE (European Certification) certfitied and through our innovative, integrated laser labeling process, we permanently mark each piece of glass in compliance with federal regulations. The Safety Glazing Certification Council (SGCC) is the largest independent third-party that inspects and test tempered glass to confirm the manufacturing process and result. Participation in the SGCC program is voluntary and satisfactory participation in the Council allows the glass manufacturer/fabricator to etch the SGCC logo permanently onto the glass, as notification that the glass has been properly produced.
Tempered glass is required as safety glazing in “hazardous” applications, such as floor-to-ceiling partition walls, entrance doors, sidelites, vehicles and furniture.
Upon completion of the tempereing process the glass cannot be further processed (cut, drilled or further fabricated).
