Heat strengthened glass is a semi-tempered material that is twice as robust as annealed glass.
It is mechanically and thermally stronger than annealed glass of the same width and thickness.
Heat-strengthened glass is more difficult to break than annealed glass.
The fundamental float glass used in this form of glass is heated to a very high temperature before
being progressively cooled.
Heat strengthened glass
experiences less internal stress because cooling occurs more quickly than Annealed glass but slower than Tempered glass. The majority of the characteristics of standard float glass are still present in this type of glass, and it's breaking pattern is quite similar to that of annealed glass. However, unlike tempered glass, this type of glass is less likely to spontaneously break.Essar Sons is the high quality
