Tempered glass is to heat the glass to a temperature lower than the softening temperature, and then conduct uniform and rapid cooling. The outside of glass will be fixed due to rapid cooling, while the inside will continue to shrink, resulting in compressive stress on the surface of glass and tensile stress on the inside. To break the tempered glass, the internal stress must be offset first, so that the mechanical strength and thermal stability of the glass are improved.

Laminated glass is sandwiched between the glass by PVB, SGP and other materials, by high temperature and high pressure processing. Laminated glass is a kind of safety glass, which is not easily broken, and even if the glass is broken, it can still maintain a relatively complete form.

Tempered glass breaks into smaller pieces, and laminated glass will crack but remain together due to the plastic layer that is baked between the two pieces of glass.

Tempered glass is much stronger than laminated glass and better at resisting force up to certain levels. Laminated glass is favored for security purposes, particularly in commercial buildings. The layer of PVB makes it much harder to breach, despite it not being as strong.

Today the laminated glass commonly used in windows for tall buildings, skylights, and frameless glass railings. Tempered glass is widely used in doors and windows of buildings, glass curtain walls, indoor partitions, lighting ceilings, sightseeing elevator passages, glass corridors, furniture, glass guardrails, etc
