The strength of tempered safety glass depends on the heat treatment performed on the glass. The glass is heated to a temperature of about 10 degrees Celsius. 650°C, when the glass softens and the tension disappears. Afterward, the glass cools rapidly, at this time the glass surface maintains a constant compressive stress, and the middle part maintains a constant tensile stress.
The design is often based on the need for larger curved glass surfaces, concealed fixings and structures without sashes and frames. Tempered curved glass is a logical alternative for these challenging structures due to better durability, safety and larger glass sizes.
