Laminated Vs Tempered Glass Skylight
Tempered glass meets the safety glazing codes because it fractures into small fragments when broken. Acrylic, used in many standard skylights, is the least expensive and most formable of the skylight options. Alibaba.com offers 80 laminated glass vs tempered glass skylights products. About 1% of these are building glass. A wide variety of laminated glass vs tempered glass skylights options are available to you, such as clear glass, laminated glass, and frosted glass.
Tempered glass and laminated glass have different properties. They are two different types of glass but can be used together in some applications. Laminated, tempered glass is a common marriage of the two types of glass. Separately, each type of glass has useful applications.
History
Tempered Vs Laminated Glass Skylight
The chemist Edouard Benedictus invented laminated glass in 1903. He hoped that the glass-plastic combination would reduce car-related injuries. His invention however, was not used in automobiles for several years. The idea of tempered glass has been around for centuries. Rudolph Seiden of Austira was the first to patent a design for tempered glass.
Applications
Tempered glass is commonly used in frameless glass doors used in commercial settings. Passenger windows in vehicles are usually made of tempered glass. The windshields in automobiles are typically made of laminated glass, as is the glass commonly used in skylights. Laminated glass is often used in applications where there is a severe risk of high winds.
Laminated Glass
Laminated glass is produced by bonding layers of glass together under pressure and heat, with a resin called PVB (polyvinyl butyral). This technique is used to create single sheets of glass with multiple layers. The PVB keeps the glass from breaking apart easily and provides high sound insulation. Laminated glass will flex before shattering. Laminated glass is strong but not as strong as tempered glass. Also, laminated glass blocks nearly 99 percent of ultraviolet light transmission.
Tempered Glass
Tempered glass is also sometimes called toughened glass. It is very strong and is often used as safety glass. When tempered glass is broken, it will usually break into very small pieces instead of into big shards. This makes it less likely to cut a person. Tempered glass is known to be several times stronger than laminated glass. Tempered glass is created using chemical and thermal treatments. The treatments give it more balanced internal stress capabilities.
Cost
Laminated glass is generally more expensive then tempered glass. Until recently, laminated glazings used to cost three to four times as much as tempered glass. It is mandatory for car manufacturers to use laminated glass in windshields. More companies are using laminated glass in side and rear windows.
Laminated Tempered Glass
The science behind laminated glass and tempered glass can be combined to make laminated glass that is also tempered. When manufacturing this type of glass, the thickness of PVB used has to be just right or some level of bubbling can occur at the edges. This is a difficult process but if successful, laminated tempered glass can have many useful applications. Many car manufacturers are using this technology in their windows now. However, most car companies still choose to use one method over the other.
