AIS Heat Treated Glass

Heat treatment is a process used to enhance the strength and durability of glass by subjecting it to controlled heating and rapid cooling. It is characterized by safety, high strength and thermal stability. The two main types of heat-treated glass types are Heat Strengthened and Tempered glass. 

Heat-strengthened glass is a type of heat-treated glass that has undergone a controlled thermal process to enhance its strength compared to standard annealed glass. This process involves heating the glass to a temperature just below its softening point and then cooling slowly, inducing surface compression and increasing its resistance to thermal and mechanical stresses. It is 2 times stronger than annealed glass. 

Tempered glass (also known as toughened glass) is a type of safety glass that is processed by heating annealed glass to around 620°C–680°C and then rapidly cooling it (quenching) to introduce high surface compression and tensile stresses in the core. This process makes it 4–5 times stronger than annealed glass of the same thickness. Once toughened, they can no longer be cut or shaped. AIS manufactures this glass under the brand name of AIS Stronglas.
