Difference Between Coated Glass And Tinted Glass. In this article, you will come to know about what is coated glass, what is tinted glass, what is the main difference between coated glass and tinted glass, and much more.

Both the terms coated glass and tinted 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 lay in their making process. Here, we will first discuss the main difference between coated glass and tinted glass, then differentiate between them in detail.

What Is The Main Difference Between Coated Glass And Tinted Glass?

The main difference between coated glass and tinted glass is that the:

-Coated Glass is produced by applying the coating to the finished glass through a process called sputter coating. Various metal oxides are sprayed in the form of thin coatings from 0.01 µm to 0.8 µm.

-Tinted Glass is a heat-absorbing glass that is made by adding colour to the raw materials during the float process. The floating process is a mixture of sand and organic material, then moving it to the float bath. The materials are slowly cooled down and a smooth glass is formed.

What Is Coated Glass?

Coated Glass is produced by applying the coating to the finished glass through a process called sputter coating. Various metal oxides are sprayed in the form of thin coatings from 0.01 µm to 0.8 µm. The coatings are applied by the controlled exposure of the glass to vapours.

Special coatings modify the appearance of the glass and enhance its characteristics. Like special reflection/transmission/absorption properties, scratch resistance, corrosion resistance, low maintenance, etc.

Difference Between Coated Glass And Tinted Glass - coated glass

There are two types of coated glass, i.e. Hard-coat glass and Soft-coat glass.

-Hard coat is made by pouring a thin layer of metallic oxide onto a sheet of glass while the glass is still on the float line, just after it has been formed into a thickness ribbon. The metallic oxide layer actually becomes welded to the glass surface. This process makes it very difficult or hard to scratch or remove the coating therefore why it is referred to as a hard coat. Often this glass has a bluish tint to it. Low E and Self Cleaning coatings fall under this category.

-Soft Coat involves the application of silver, zinc or tin (or a combination of) to glass that has already been formed and taken off the float line. The coating is softer than online coated glass therefore why it is referred to as a soft coat. Furthermore, if silver is used (and it often is) the offline coating can oxidise if exposed to normal air. For this reason, offline coated glass must be used in an insulated glass unit (IGU).

What Is Tinted Glass?

Tinted glass is a heat-absorbing glass that is made by adding colour to the raw materials during the float process. The floating process is a mixture of sand and organic material, and then moves to the float bath. The materials are slowly cooled down and a smooth glass is formed. The tinted glass is formed in many colours like grey, dark grey, bronze, green, blue, etc.

The transmission of light depends on the density of the glass. Because, the more the density and thickness of the glass, the density of the colour will also increase eventually decreasing the transmittance of light.

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 more 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 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.
