Difference Between Heat Strengthened Glass And Flat Glass. In this article, you will come to know about what is heat strengthened glass, what is flat glass, what is the main difference between heat strengthened glass and flat glass, and much more.

Both the terms heat strengthened glass and flat glass are the types of glasses that are used in construction and for different purposes. Glass is a transparent substance that can be transparent, translucent, or brittle. The process that is used to manufacture the glass is known as the ‘fusion process’. In this process, the sand is fused with soda, lime, and various admixtures. Then this mixture is cooled rapidly, thus forming a glass.

The difference in the glasses lied in their making process. Here, we will first discuss the main difference between heat strengthened glass and flat glass, then differentiate between them in detail.

What Is The Main Difference Between Heat Strengthened Glass And Flat Glass?

The main difference between heat strengthened glass and flat glass is that the:

-Heat Strengthened Glass is made by the same process used in making tempered glass, but the cooling process is slower. This results in a lower surface compression of 3,500 to 7,500 psi, which makes it stronger than annealed glass.

-Flat Glass is made in furnaces from sand and organic material. The molten glass is then spread on a metal plane sheet, which makes the flat glass.

What Is Heat Strengthened Glass?

Heat Strengthened Glass is made by the same process used in making tempered glass, but the cooling process is slower. This results in a lower surface compression of 3,500 to 7,500 psi for 6mm glass, which makes it stronger than annealed glass. It has more resistance to thermal loads and is stronger as compared to annealed glass.

This glass is also referred to as semi-tempered. That’s why it cannot be used as a safety glass. It cannot be cut, drilled, edge-ground, or sandblasted after the heat strengthening. Heat-strengthened glass is shattered like tempered glass, however, it got fractured into dangerous large shards.

Heat strengthened glass is used in laminated glass to give it extra strength, for example, overhead and sloped glazing.

What Is Flat Glass?

Flat Glass is made in furnaces from sand and organic material. The molten glass is then spread on a metal plane sheet, which makes the flat glass. it can be made according to desired thickness and then cooled the mixture into the final product. This glass is flat like a sheet of paper. It is also known as ‘sheet glass’ and ‘plate glass’.

The flat glass is used in solar panels, doors, windows, automotive glass, and mirrors. It can be easily cut, finished, treated, temper, coat, or infused with texture or colour.

What Are The Properties Of Glass?

The 6 main properties of glass are as under:

1.Transparency:

The main property of glass is transparency. The transparent the glass, the better the vision of that glass. Usually, the glasses are transparent from both sides, but there is some glass that is transparent from one side only. An example of such types of glasses are mirrors that have only one side transparency.

2.Strength:

The strength of glass is the second property of glass. It depends on the modulus of the ruptured value of glass. The glass is very brittle initially. We add admixtures and laminates to make it more stronger.

3.Workability:

The workability of the glass is a superior property. Glass can be moulded into any shape when melted.

4.Transmittance:

A glass should have visible transmittance property. It means that a visible fraction of light should pass through the glass.

5.U-value:

The u-value of the glass is the amount of heat that can be passed through the glass. Like, if the glass is insulated the glass will have a lower u-value.

6.Recyclable:

A glass can always be recycled. It has 100% recyclable property. It is used as a raw material in the construction industry.
