Tempered glass (sometimes reffered as toughened glass) is heat treated so it can withstand greater temperatures, impact and mechanical stress. Tempered glass conforms to safety glass category. Glass that has been tempered is 4 to 5 times st...

Heat Strengthened
Heat strengthening is a special heat treatement process to increase the mechanical and thermal strength of glass making it twice as tough as annealed glass.
The glass is heated to a uniform temperature of approximately 650 °C to 700 °C. Ceramic rollers move the glass through the furnace at a regulated speed to ensure temperature uniformity and minimal distortion.
The process is similar to the traditional process of glass tempering, but the cooling cycle is less rapid.
However, the heating temperature remains the same for both processes.
Due to the relatively lower rate of cooling during the heat strengthening process, heat strengthened glass develops less stress as compared to fully tempered glass.
The main application for heat strengthened glass is skylight installations.
