Annealed, Tempered, or Laminated Glass?

leave a comment »

Tempered glass and annealed glass are different in composition and applications. Tempered glass is the more popular but there are many uses for simple annealed glass. Tempered glass is valued for its safety and strength, but when neither of those factors is an issue, annealed glass is a good, less expensive choice.

When tempered glass is shattered it breaks into round pieces that pose no risk. When annealed glass (commonly refered to as double or triple strength) is shattered it breaks into sharp jagged pieces able to inflict serious injury or death. As noted above building codes require the use of tempered glass in certain installations depending on the risk of breakage.

As a general rule of thumb, glass less than 24 inches from the ground or floor should be tempered, as well as any glass within a door or its adjacent sidelites.
