Toughened 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.

Product Description

Clear Glass is a glass manufactured in the float line without any tint, allowing it to be transparent in nature. This transparent and clear finish ensures clarity of vision with true colours of the objects. Clear glass is very versatile and finds a wide range of applications in partitions, doors, furniture, display cabinets etc.

The grade and quality of a clear glass is determined by iron content (measured in PPM – Parts per Million) in Silica-sand, a key raw material in making of glass. Lower the iron content, clearer and purer is the glass. Saint-Gobain plants in India manufacture clear glass with low PPM levels of 654. By bringing down the iron content to just 654 PPM with the help of manufacturing efficiency and technological advancement, Saint-Gobain brings, what is clearly, the purest glass.

That is why 654 PPM clear glass from Saint-Gobain glass is "Purity ka Perfect Measure".

HOW TO CHECK FOR CLARITY AND PURITY

 

To check the clarity and purity of any glass, one needs to see it sideways; lesser the greenish tint of the glass, the higher will be its clarity and purity.

Saint-Gobain has made it easier for you to remember the correct method of checking glass with its tagline- “Dekho..Magar Side Se” which also prompts the customer to check out the logo.

With Saint-Gobain the thickness tolerances are set as per the stringent most European standards. This ensure that the glass is of the right thickness as opposed to the other ordinary products available. All Saint-Gobain products come with the proprietary TruThik promise and ensure higher strength, high sound insulation and higher impact resistance when compared to others.
