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

Both the terms heat strengthened glass and shatterproof 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 shatterproof glass, then differentiate between them in detail.

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

The main difference between heat strengthened glass and shatterproof 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.

-Shatterproof Glass is a laminated glass, which is made by bonding two glass sheets with the interlayer of resin, polyvinyl, or some other compounds.

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 Shatterproof Glass?

Shatterproof Glass is a laminated glass, which is made by bonding two glass sheets with the interlayer of resin, polyvinyl, or some other compounds. It is also known as ‘security glass’. This glass is not easily breakable, however, when it breaks, the glass pieces do not shatter all the way. They remain intact in their place like a spider web. It is shatter-resistant glass.

Shatterproof glass is used in windows, floors, skylights, etc. Some advantages of shatterproof glass are:
-Gives protection against forced entry.
-Increases safety during unexpected accidents.
-Low energy costs.
-Reduce the sound transmission.
-Prevents any damage during a natural calamity.
-Provides protection from UV rays.

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.
