Glass

Product Details:

Toughened  glass or tempered glass is glass that has undergone processes of controlled thermal treatment to increase its strength. It is four times stronger than normal annealed glass. Toughened glass is made from annealed glass that has been heated to approximately 650???C and then rapidly cooled. Due to the increased heat treatment and rapid cooling of the glass, the treatment produces different physical properties. This results in compressive stress on the surface and improved bending strength of glass. Before toughening, the glass must be cut to size or pressed to shape.

Characteristics of Toughened Glass:

Toughening does not alter the basic characteristics of glass like light transmission and solar radiant heat properties of normal glass. It can neither be cut, nor altered. Toughened glass is known to have higher thermal strength, with the ability to withstand high temperature changes up to 250°C. A safety glass, toughened glass is difficult to break but in the event of a breakage, disintegrates into small globules . However, it is prone to very rare spontaneous breakage, a condition that occurs when the repeated heating and cooling cause the nickel sulfide stones to increase in size.

Annealed Glass vs Toughened Glass: 

 

The Process of Toughening:

First, the glass is carried by rollers and goes through the furnace. Here, three types of modes are used to heat the glass, viz., conduction, convection and radiation. While the rollers help to conduct the heat, the coils enable radiation of heat. This ensures that the glass is evenly heated on every side. By blasting air on both the surfaces, the heated glass is then cooled uniformly.

Why the Need for Toughened Glass:

 

Toughened Glass has high withstanding capacity and is therefore suitable for uses where strength and thermal resistance are crucial. It is nearly four to five times stronger than annealed glass, and thrice as strong as heat strengthened glass. Even during breakage, its relatively small pieces reduce the chances of injury. Toughened Glass is ideal in spider and point fixed glazing owing to its high edge strength tempered glass. Glass is susceptible to thermal breakage with drastic changes in temperature. This is more so when temperature rises above 32°C, building up stress within the glass. But with toughened glass, there is significantly higher edge strength to resist thermal breakage.

What makes Toughened Glass ideal for homes:

 

Toughened Glass is the ideal solution for every space that demands the highest level of safety, and hence perfect for homes
