Toughened Glass: A Safer Choice

Toughened glass, also known as tempered glass, is a type of glass that has been treated with a process that makes it stronger and more resistant to breakage. This process involves heating the glass to a high temperature and then rapidly cooling it. This causes the glass to become more dense and its surface to become harder.

One of the main benefits of toughened glass is that it is much stronger than ordinary glass. It is typically four to five times stronger, which makes it much less likely to break. Even if it does break, toughened glass tends to fracture into small, blunt pieces, rather than sharp shards. This makes it a much safer choice for use in areas where there is a risk of breakage, such as in windows, doors, and shower screens.

Another benefit of toughened glass is that it is more resistant to heat and cold. It can withstand temperatures of up to 250 degrees Celsius, which makes it ideal for use in areas where there is a risk of fire. Toughened glass is also less likely to crack or shatter when exposed to extreme cold.

Due to its increased strength and safety features, toughened glass is often used in a variety of applications, including:

• Windows
• Doors
• Shower screens
• Table tops
• Car windscreens

Toughened glass is a versatile and durable material that offers a number of benefits over ordinary glass. It is stronger, safer, and more resistant to heat and cold. This makes it a good choice for use in a variety of applications, from windows and doors to shower screens and table tops.
