what is tempered glass
Tempered glass, also known as toughened glass / ESG. Tempered glass is a specially treated safety glass that increases its strength through a heating and cooling process. In this process, the glass is heated to a high temperature and then cooled rapidly, which causes compressive stress to form on the surface of the glass. When the glass is subjected to external forces, the surface stress is first offset, thereby increasing the bearing capacity and making it stronger and more resistant to breakage than ordinary glass. It also enhances the glass’s own resistance to wind pressure, cold and heat, impact, etc. If it does break, tempered glass will break into small round pieces instead of sharp pieces, making it safer.

- Energy Efficiency: In some applications, such as windows and doors, tempered glass can help improve energy efficiency by providing better insulation. This can lead to lower energy bills.
Sound Insulation
Noise Reduction: Tempered glass can help reduce noise transmission, making it a good choice for applications where sound insulation is important. This can be particularly beneficial in urban environments or in buildings near busy roads.
UV Protection
- UV Resistance: Tempered glass can block a significant amount of UV radiation, protecting interiors from fading and damage. This is especially important for items such as furniture, artwork, and flooring that are exposed to sunlight.
Easy Installation
- Professional Installation: While tempered glass should be installed by professionals, the process is generally straightforward. This ensures that the glass is installed correctly and safely, providing optimal performance.
Compliance with Regulations
Safety Standards: Tempered glass meets various safety and building codes, ensuring compliance with regulations. This is particularly important for commercial and public buildings where safety is a top priority.
Toughened Glass Features
1. Strong and durable: Tempered glass is stronger than ordinary glass, resistant to falling and scratching, and not easy to be damaged.
2. Easy to clean: The surface of tempered glass is flat and smooth, not easy to absorb dust and dirt, and easy to clean.
3. Beautiful: Tempered glass has high transparency and beautiful appearance, allowing light to penetrate freely without affecting indoor lighting.
4. Good thermal stability: Tempered glass has been treated with high temperature and has good thermal stability and high temperature resistance.
5. High safety: Even if tempered glass is broken, it will not scatter into sharp fragments like ordinary glass, but will break into small particles without sharp corners, reducing harm to the human body.
Tempered glass production process
The production process of tempered glass mainly includes cutting, edge grinding, cleaning, and tempering.
The original glass is cut into the required size and then edged to prevent self-explosion due to edge defects during the tempering process.
The glass is cleaned to ensure that no impurities adhere to the glass surface during the tempering process.
The cleaned glass is placed in a tempering furnace, and compressive stress is formed on the glass surface and tensile stress exists in the glass body by heating and rapid cooling, thereby obtaining tempered glass.

FAQ
What is the price of tempered glass?
The price varies depending on size, thickness and customization needs. Please consult customer service for specific prices. On average, tempered glass can range from $10 to $50 per square foot, but prices can increase with additional features like color, etching, or special finishes. It’s best to get a quote from a supplier based on your specific needs.
What is the tempered glass thickness?
1. 3mm and 4mm tempered glass: These two thicknesses of tempered glass are thinner and are generally used in lightweight structures such as indoor partitions, doors and windows. They have good light transmittance but weak load-bearing capacity.
2. 5mm and 6mm tempered glass: These two thicknesses of tempered glass are more common and are widely used in home decoration, building curtain walls, doors and windows, etc. They not only ensure good perspective, but also have a certain load-bearing capacity.
3. 8mm and 10mm tempered glass: These two thicknesses of tempered glass have strong load-bearing capacity and are usually used in large building curtain walls, balcony partitions, stair handrails and other occasions that need to bear a certain weight.
4. 12mm, 15mm, and 19mm tempered glass: These thicker tempered glasses have extremely high load-bearing capacity and safety, and are often used in curtain walls and partitions of important places such as high-rise buildings, large shopping malls, and stadiums.
How safe is tempered glass?
Tempered glass is considered very safe because of its ability to break into small, rounded pieces, reducing the risk of injury. It’s commonly used in places where safety is a priority, such as in shower doors, car windows, and balcony railings. However, like any material, it’s important to ensure that the glass is installed properly. While tempered glass is designed to be strong, it can still break under extreme conditions, such as high impact or intense heat.
Disadvantages of tempered glass
1. After tempering, the glass cannot be cut or processed. It can only be processed to the required shape before tempering.
2. Although tempered glass is stronger than ordinary glass, it has the possibility of self-explosion (breaking by itself), while ordinary glass does not have the possibility of self-explosion.
3. The surface of tempered glass will be uneven (wind spots) and slightly thinner. The reason for the thinning is that after the glass is softened by hot melt, it is quickly cooled by strong wind, which makes the crystal gap inside the glass smaller and the pressure greater. Therefore, the glass is thinner after tempering than before tempering. Generally, 4~6mm glass becomes 0.2~0.8mm thinner after tempering, and 8~20mm glass becomes 0.9~1.8mm thinner after tempering. The specific degree depends on the equipment, which is also the reason
4. Flat glass used in buildings will generally be deformed after passing through a tempering furnace (physical tempering). The degree of deformation is determined by the equipment and the craftsmanship of the technicians. To a certain extent, it affects the decorative effect (except for special needs).
What is the difference between tempered glass and regular glass?
Tempered glass is stronger and safer than ordinary glass, does not form sharp fragments when broken, and has better heat and impact resistance.
Can tempered glass be customized?
Yes, tempered glass can be customized in various ways. You can choose from different thicknesses, colors, and even types of surface treatments (like frosted or tinted glass). Additionally, tempered glass can be cut to specific sizes and shapes to fit various applications, such as shower doors, glass tables, or windows. Customization options also include edge finishing (e.g., beveled or polished edges) depending on the project’s needs.
How long does it take to install tempered glass?
The installation time for tempered glass depends on several factors, such as the complexity of the installation and the size of the glass. For example:
- For a shower door, the installation can typically take between 1 to 3 hours.
- For larger projects, like glass windows or balcony railings, installation may take several hours or even a few days, depending on the size and scope of the project. It’s important to hire professional installers to ensure that the tempered glass is properly fitted and secured.
What is the warranty policy for tempered glass?
The warranty policy for tempered glass varies depending on the manufacturer and the supplier. Many tempered glass products come with a limited warranty that covers defects in material or workmanship. Typically, the warranty might last anywhere from 1 year to 5 years.
