Glass Expert discusses Why Tempered Glass Is Safety Glass
Tempered glass is safety glass because it breaks into small cubes. The edges of these cubes are still sharp. They are not “rounded”. From a glass expert point of view, the safety aspect comes strictly from the small size, which is a function of the temper stress. If these pieces are interlocked, they can behave […]
Video of Tempered Glass Failure
Read Consulting glass failure experts filmed in real-time the failure of a 7′ x 1′ u-shaped piece of tempered glass. The objective was to demonstrate how rapidly the glass falls apart and to assess the danger to one standing underneath a failed piece of tempered glass. Tempered glass self destructs once its compressive layer has […]
