What Is The Difference Between Tempered Glass And Regular Glass?

What is the difference between tempered glass and regular glass?

Tempered glass and regular glass, also known as annealed glass, differ in terms of their manufacturing process, strength, safety, and thermal properties. Here are the key differences between tempered glass and regular glass:

Manufacturing Process: Tempered glass undergoes a thermal tempering process, which involves heating the glass to a high temperature and then rapidly cooling it. This process creates internal stresses within the glass, resulting in increased strength and durability. Regular glass, on the other hand, is cooled slowly during the manufacturing process, without undergoing any additional treatments.

Strength and Safety: Tempered glass is significantly stronger than regular glass. It is designed to be up to four to five times stronger than annealed glass of the same thickness. When tempered glass breaks, it shatters into small, blunt, and relatively harmless pieces, known as granules or cubes, reducing the risk of severe injuries. In contrast, regular glass breaks into sharp and potentially dangerous shards.

Resistance to Thermal Stress: Tempered glass has higher resistance to thermal stress compared to regular glass. It can withstand rapid temperature changes without cracking or breaking. This property makes it suitable for applications where exposure to high temperature variations is expected, such as oven doors, fireplace screens, and certain automotive glass.

Usage and Applications: Tempered glass is commonly used in situations that require increased safety and strength. It is widely employed in applications such as glass doors, shower enclosures, table tops, windows in high-rise buildings, and automobile side and rear windows. Regular glass is often used in applications where safety or strength is not a primary concern, such as picture frames, basic windows, and some household glassware.

Cut and Alteration: Tempered glass cannot be cut or altered after the tempering process. Any attempts to modify or cut tempered glass will cause it to shatter into small granules. Regular glass, however, can be easily cut, drilled, and shaped to specific requirements.

It's important to note that while tempered glass is stronger and safer than regular glass, it is not impervious to damage or breakage. Extreme force or impact can still cause tempered glass to break, albeit in a safer manner compared to regular glass.

When choosing between tempered glass and regular glass, consider the specific application, required safety standards, and any thermal stress or strength considerations to determine the most suitable option.If you have any questions, you can consult us at any time, we will give you professional advice！
