Toughened Float Glass
Even though laminated glass meets all current safety requirements, toughened float glass is required to be used in certain instances. If this type of glass is broken, it will shatter; however, the pieces themselves, while small, are not dangerous whatsoever.
Although this safety feature is extremely important, the main reasons for this type of glass being used include thermal resistance and an increased amount of strength of up to five times that of annealed glass. Some of the most common applications of toughened glass include the following:
- Frameless assemblies
- Shower screens
- -Semi-frameless balustrades
The only real and unfortunate downside to this type of safety glass is that while the actual toughening process itself takes place, the glass becomes slightly corrugated and distorted, which can be visible when it is inspected closely.
Furthermore, once the glass itself becomes toughened, there is no way for it to be altered or cut in any way, shape, or form. This means that each glass panel is cut and processed in order to create customized products that essentially can’t be used in other locations. Also, if the glass breaks, the entire sheet disintegrates, which essentially eliminates all of its security benefits.
