There are different ways that glass is manufactured in order to improve its quality and safety. These different kinds of glass that result from these manufacturing techniques include safety glass and construction glass.
Safety glass is manufactured to resist breaking. When it does break, it is designed to break in such a way that it is less likely to cause injuries. This kind of glass is used in a variety of applications. Automobiles frequently have safety glass installed in their windshields. Glass used in laboratories is often safety glass. This kind of glass is also used in eyeglasses and in windows that are installed in homes.
The benefits of safety glass can be measured easily when compared to other kinds of glass. Before the invention of safety glass, glass windows and objects could potentially be very dangerous. In the event that they broke, they could cause deep cuts and lacerations. Some people who have had this experience have had to undergo amputations or have suffered extensive scarring due to these injuries.
Glass lamination is the procedure by which safety glass is created. This is a procedure in which a layer of polyvinyl butyral material is placed in between two individual sheets of glass. This interlayer is what prevents the glass from shattering into thousands of pieces. If something should hit the glass or if too much pressure is exerted on it, it cracks in what is known as a spider web pattern, but it is still in one piece. The place of greatest impact is usually the center of the spider web, and the cracking pattern tends to extend outward from this point.
Glass lamination has several benefits, one of which is of course safety. If someone gets into an accident driving an automobile fitted with laminated glass, they are protected from being injured by shattering glass, or by being thrown through the windshield. Glass lamination is also helpful in the event that an attempt is made at car theft, because it is very difficult to break the glass from the outside in order to gain access to the vehicle.
Construction glass is thicker than other kinds of glass. It may be referred to as toughened glass. It is a kind of safety glass that is used in skylights, conservatories, glass staircases, and balconies. Construction glass is between four and five times stronger than regular glass, and is not only difficult to break but is resistant to temperature extremes such as excessive heat.
