Difference Between Insulated Glass And Annealed Glass. In this article, you will come to know about what is insulated glass, what is annealed glass, what is the main difference between insulated glass and annealed glass, and much more.
Both the terms insulated glass and annealed 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 insulated glass and annealed glass, then differentiate between them in detail.
What Is The Main Difference Between Insulated Glass And Annealed Glass?
The main difference between insulated glass and annealed glass is that the:
-Insulated glass is made by adding two or more tiles of glasses. These glasses are separated by a sealed air space or an inert gas that adds extra barriers to cold and heat transfer. The glasses used as insulation can be tempered glass or annealed glass.
-Annealed glass is known as standard glass. It is thermally treated. This glass is then slowly cooled down to relieve the internal stresses.
What Is Insulated Glass?

Insulated glass is made by adding two or more tiles of glasses. These glasses are separated by a sealed air space or an inert gas that adds extra barriers to cold and heat transfer. The glasses used as insulation can be tempered glass or annealed glass. Insulated glass is also known as double glazing glass and insulated glazing unit. It costs up to $10 per square foot and up. This glass lasts up to 15 to 20 years, seal around the glass panes leaks, and the inert gas escapes. When this will happens, the insulating power of the window will be lost.
What Is Annealed Glass?
Annealed glass is known as standard glass. It is thermally treated. This glass is then slowly cooled down to relieve the internal stresses. It breaks into highly harmful large and longer shards that often cause injuries.

Annealed glass is usually used as a base glass to form other types of glasses. It is the minimum standard of glass. Annealed glass is clear glass that is used in windows doors. You can use it, if safety is not the concern but the cost is.
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.
