Tempered Glass

Tempered glass, commonly referred to as fully tempered, is designed for glazing hazardous locations. Upon impact, tempered glass shatters into small fragments to prevent the likelihood of serious injuries as with the large break pattern of annealed glass. Tempered glass is generally four times stronger than annealed glass and twice as strong as heat-strengthened glass of the equivalent thickness, size, and type.

Features

BENEFITS

Meets the safety glazing requirements for fully tempered glass or CPSC 16 CFR 1201 and ANSI Z 97.1

For use in safety glazing applications subjected to wind loads and thermal stresses

Break pattern results in small fragments

Four times stronger than annealed glass

Tested and approved by the Safety Glazing Certification Council (SGCC)

DESIGN CONSIDERATIONS

Fully tempered glass is required in ASTM C 1048 to have either a minimum surface compression of 10,000 psi (69 MPa) or an edge compression of not less than 9,700 psi (67 MPa) or meet ANSI Z 97.1 or CPSC 16 CFR 1201. The higher compression levels yield a product that is generally four times stronger than annealed glass and twice as strong as heat-strengthened glass.

APPLICATIONS

Tempered glass is required by the building code for glazing areas that have been defined as hazardous locations. These include but are not limited to all-glass entrances, doors, sidelites, curtain walls, handrails, partitions, storefronts, windows, shower enclosures and other glazing in close proximity to a door or walking surface.
