Heat Strengthened Glass

What is Heat strengthened glass? What are the differences between Heat Strengthened Glass and tempered glass?

Heat strengthened glass is also called semi-tempered glass. It is a type of glass that introduces a permanent stress layer on the surface of the glass by controlling the heating and cooling process, which improves the mechanical strength and heat impact resistance of the glass and creates glass products with specific fragment characteristics.

Semi-tempered glass is a type of glass that falls between ordinary flat glass and tempered glass. Both are strengthened glass, with the strength of semi-tempered glass being 1-2 times that of ordinary flat glass, while tempered glass is 3-5 times.

The differences between the two are as follows:

Tempered glass is safety glass, which breaks into small particles and will not cause serious harm to people. Relevant departments in the country require the use of tempered glass in certain parts of buildings. Semi-tempered glass is non-safety glass, which still has large pieces of glass and sharp edges after breaking, which can seriously injure people, but there is no risk of spontaneous explosion. It is often used in glass curtain walls.
Tempered glass needs to pass the mandatory (3C) certification of the country and has strict physical and chemical performance testing requirements, and national designated institutions supervise the product performance and production process. Semi-tempered glass also has quality requirements but is not mandatory.
Both require the use of a tempering furnace for heat treatment, but the cooling capacity of semi-tempered glass is lower than that of tempered glass.

What is the application of heat strengthened glass?

Heat strengthened glass is commonly used in architectural and construction applications where safety, durability, and thermal stability are required.

Some of the applications of heat-strengthened glass include:

Building facades: Heat-strengthened glass is used in the construction of exterior building facades, curtain walls, and glass canopies. It offers improved resistance to wind loads, thermal stress, and impact resistance.

Windows and doors: Heat-strengthened glass is used in the manufacture of windows, doors, and skylights, where its improved strength and resistance to thermal stress make it a popular choice.

Solar panels: Heat-strengthened glass is used in the manufacture of solar panels, where its high strength and durability help to protect the delicate solar cells from damage.

Glass balustrades: Heat-strengthened glass is used in the construction of glass balustrades, where its improved strength and resistance to breakage provide a safe and attractive barrier.

Glass floors and stair treads: Heat-strengthened glass is used in the construction of glass floors and stair treads, where its high strength and durability provide a safe and elegant solution.
