Heat strengthened glass is another type of safety glass that is stronger than normal glass but slightly less strong than toughened safety glass. It is made using a heating and controlled cooling process, similar to the process used for tempered glass.

The difference is that heat strengthened glass is cooled more slowly than toughened glass. Because of this, it has lower internal stress compared to fully toughened glass but still offers better strength than standard glass.

Heat strengthened glass is often used in architectural applications where additional strength is needed but full toughened glass may not be required. It is commonly used in building facades, curtain walls, windows, and structural glazing systems.

Another advantage of heat strengthened glass is that it breaks in larger pieces compared to toughened glass, which can sometimes be useful for certain design and engineering applications.

Many construction projects work with a reliable toughened glass manufacturer in India that also produces heat strengthened glass for commercial buildings and architectural glass installations.
