There is no difference; they are one and the same. For example, the law requires that tempered glass be used in doorlights, bathroom windows near tubs or showers, and windows with glass that is within 18 inches of the floor. On the other hand, untempered glass is allowed to cool slowly and, therefore, will react to breakage differently. Each type of glass is designed to meet specific requirements related to solar control, decoration, security, acoustics, and architecture. Once the result of this process is shaped formed, and cooled, a process called annealing reheats the glass and cools it once again for restoring strength. When tempered glass breaks, it breaks into small pebble shaped pieces like a cars windshield after an accident. Float glass manufacturers create low-iron glass, also known as extra-clear glass or optically clear glass, by reducing the amount of iron in the molten glass formula. This type is more transparent than regular glass, and doesn't have that greenish tint. Tempered Glass Windows are a type of fixture that uses a safety glass and is ideal in homes or building that requires a sturdier window than the standard glass. I am very, very pleased with their knowledge and abilities, they were the most impressive group of people I have ever worked with. If the edges of the glass are exposed, run your fingers along them.

If you want to learn more about the differences between regular glass and tempered glass, call Wallside Windows at (313) 908-5243. Normally, tempered glass has completely smooth edges due to the extra processing it goes through, while other types of glass usually have scuffed or ridged edges. All these layers make tempered glass up to five times stronger than normal glass. Tempered or toughened glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. Plate glass is usually harder because of the intense heating and a gradual cooling process to make it sturdier. When it does shatter, however, is where the other unique aspect of tempered glass comes in. Look for a small label etched into the mirror that says "tempered" or "safety glass" at one of its four corners. Tempered glass is much stronger than regular glass.

How Do Tempered Glass and Regular Window Glass Compare. So, one good way is to look thoroughly at the edges of the glass.

Standard glass breaks into large, irregular shaped shards. Understanding the different types of glass available can help you make the best decision for your next window replacement project. When the glass absorbs heat or light energy, the glass can either shift it away by air, or re-radiates by the glass surface. Cutting, reshaping, polishing edges and drilled holes are some customizations that can be done without breaking or shattering regular glass. Tempered glass, often referred to as toughened glass, is a type of safety glass that is treated with heat or chemicals to increase its strength compared to normal glass.
