Features of tempered glass

For the average person, glass is a fragile material that can be easily broken. At the same time, it forms many small fragments that can cause serious damage. At one time, scientists took into account these shortcomings and began to work on creating such a glass that would be as safe and at the same time aesthetically attractive as possible. As a result, a more elegant, lightweight and safe material called tempered glass appeared on the construction market.

Such glass is significantly superior to ordinary glass in many technical and operational parameters, which allowed it to quickly become popular throughout the world. Today, without tempered glass, it is impossible to imagine any branch of the national economy, which with its help made a big step forward in its development.

The process of tempering glass somewhat resembles the tempering of steel. The glass is first heated until it reaches a plastic state, after which it cools rapidly. Its inner layers cool much more slowly than the outer ones, which leads to the occurrence of residual compressive stresses. They give the glass a higher temperature resistance and durability.

If you hit a tempered glass, it is broken in the same way as usual, but its fragments are much safer. In addition, the number of small pieces of material strictly complies with current standards. For example, if a hammer with a weight of 75 grams hit a sheet of tempered glass, then it should form at least 40 fragments 100x100 millimeters in size or at least 160 pieces with parameters 50x50 millimeters. The greatest danger, as you know, is carried by the edges of the glass; therefore, strikes on it should be avoided in every way.
