Tempered Glass vs. Regular Glass: A Comprehensive Guide

Glass has become the main part of modern architectural designs. It has long been used for decorative, security, functionality, and many other purposes.

But the main question is tempered glass vs regular glass, which one is better? And which one to go for?

While using glass for so many purposes, it has to be strong and robust to withstand damage, certain threshold shocks, or even fire. Here tempered glass wins.

Tempered glass is the most popular safety glass used for many challenging applications and where safety is of utmost importance.

Tempered glass or safety glass differs from standard glass because of its strength and capability to break into small and less sharp glass pellets. The regular glass will, however, break into large jagged, and sharp pieces that can be a severe threat to anyone around.

Here is all you need to know about tempered glass vs regular glass.

Why use tempered glass when the regular glass is available at a cheap rate?

The primary reason for using tempered glass instead of regular glass is because of the increased safety it provides. Although regular glass is available at quite cheaper rates as compared to tempered glass, this price difference can be ignored when safety is a priority.

When tempered glass breaks, it shreds evenly throughout the sheet, making it safer and thus causing fewer injuries. The glass spreads into small pieces that are not sharp, therefore, they don’t cause any harm or injury to people around.

On the other hand, if a regular glass breaks, it can be extremely lethal. It spread into sharp pieces that can cause injury to people around or if touched.

What are the other features that make tempered glass a better choice than regular glass?

Understanding the difference between these two types of glasses becomes clearer if their features and specifications are adequately comprehended.

Features of Regular Glass

• Regular glass goes through the annealing process where it is cooled down slowly. It is the main reason that makes it not a safety glass to be used.
• The process through which it is made, i.e. annealing, leaves no stresses and tension within the glass, making it brittle and fragile.
• Regular glass gets manufactured easily and allows maximum production, making it beneficial for the manufacturer.
• Regular glass can easily be worked on again. You can reshape, cut, polish the edges and even drill holes to customize it according to your needs and requirements.
• Regular glass is preferred if you are not sure of the design required and need to alter it.
• It is available in a lot of colors and shapes and can also be custom made.

Features of Tempered Glass

• Tempered glass is both physically and thermally durable as compared to regular glass.
• Tempered glass’s inner body is put into tension while the outer surface is compressed, and this special feature of tempered glass gives its extra strength.
• The compressive stress level on the surface of glass should be at least 10, 000 psi for it to be called tempered glass.
• Tempered glass is well known for its use for safety purposes and is the most popular safety glass.
• Tempered glass is much stronger and is scratch and impact resistant.
• The tempered glass, if broken, spreads into small pieces that are almost blunt at the edges. Therefore, it will cause less harm to anyone around.
• An additional safety feature of this glass is that the glass breaks evenly throughout the glass surface without leaving any sharp shards, minimizing the risk of danger.

Tempered glass vs regular glass - Uses

Both tempered glass and normal glass have numerous applications, depending on the user’s choice and their properties.

Uses of Regular Glass

• It is commonly used in low-risk areas where safety is not a concern.
• It can be used in windows that are not much accessible and not frequently opened.
• It is frequently used in glazed areas.
• It has undergone different treatments (like toughening, laminating, insulating, strengthening, coating, tempering, etc.) to make it usable in many other products.

Uses of Tempered Glass

Tempered glass has numerous functions because it is strong as well as quite safe to use.

• It is widely used in architectural structures for walls and windows in residential buildings, commercial buildings, industries, or leisure places.
• It is used to manufacture shower doors, fridge trays, and partition walls in the house, offices, and commercial areas.
• It is commonly used to manufacture windshields and windows of passenger vehicles.
• It is widely used in the home for furniture, tabletops, shelves, doors, fireplaces, and cabinets.
• Tempered glass can also be used for making baking and cooking dishes.
• Most mobile manufacturers now used tempered glass for their mobile screens.

Tempered glass vs regular glass-Impact of temperature

Tempered glass of the same thickness and size as annealed glass will be four to five times stronger.

Moreover, tempered glass has much greater thermal resistance as compared to regular glass. Tempered glass can easily endure temperature change up to 250°C and a constant temperature of 470°F.

Tempered glass can even remain strong under uneven heating because of the extra edge strength it has.

The next question is, what is the scope of tempered glass worldwide? Let’s find out.

Scope of tempered glass in the globe: Tempered glass market

The tempered glass market is expected to increase by 5% from 2017 to 2023. The market of tempered glass is dependent on its use and the countries where it is manufactured. Growth in the automotive and construction industries has increased the demand for tempered glass.

Mexico, China, Singapore, Korea, and India are considered as emerging economies. And due to this increased and augmented growth, it is expected that the global tempered glass market will experience a significant increase in these areas.

Regulatory authorities are promoting the use of tempered glass as a standard for commercial as well as residential buildings. Thus, the demand for tempered glass is increasing in every use.

However, laminated glass is also gaining great popularity for several applications in the construction and automobile industry. Moreover, due to its cheaper price, the laminated glass industry can be a challenge to the tempered glass industry soon.

After having a complete review of tempered glass vs regular glass, I believe now you have a clear idea about why tempered glass is the better choice.

Features of Regular Glass:

• Regular glass gets manufactured easily and allows maximum production for manufacturers.
• Regular glass can easily be worked again. You can reshape, cut, polish the edges of the glass.
• Regular glass is preferred if you are not sure of the design required and alter it.
• It is available in a lot of colors and shapes and can also be custom made.

Features of Tempered Glass

• Tempered glass is more durable than conventional glass.
• Tempered glass's inner body is put into tension while the outer surface is compressed.
• Tempered glass is much stronger and has scratch resistance.
• Tempered glass breaks into dull pieces which makes it less harmful to anyone.
• Once it is manufactured in a shape, it can not be altered.
• Uses of Regular glass vs Tempered glass
• Regular glass is commonly used in low-risk areas where safety is not a concern.
• It can be used in windows that are not much accessible and frequently used.
• It is commonly used in glazed areas.
