LAMINATED GLASS PROPERTIES & MANUFACTURING PROCESS

Applications Mandatory for Windshields and available for the rest of the car.
Features If struck or impacted, the glass cracks in the shape of a spider’s web.
The interlayer PVB holds the glass fragments together.

Here are some features of laminated glass :

Security : This is the biggest reason why people want to install laminated glass. It is simply harder to break and therefore more secure.

Safety : In the event that a child in your home throws something that hits your window, it is less likely to break. Therefore, the child is safer.

Sound reduction : Laminated glass does not allow as much sound to get through as does regular glass, meaning your home will be quieter because there will be fewer outside sounds getting through.

Protection from adverse weather conditions : People who live in areas that are prone to hurricanes or tornado can rest assured that the security glass will be less susceptible to wind and hail.

Durability : Security glass windows will need to be replaced less often than regular glass windows. It simply lasts longer.

Type of glass Clear, tinted, deep tinted and coated glass
Spectral data See table below for average values given for a glass configuration of 2.1 mm (outer pane) // 2.1 mm (inner pane). Tolerances depend on production and measurement methods.

The manufacturing process for laminated glass:
 

Automotive windows are usually made from laminated glass for windshields and tempered glass for sidelites and backlites. Laminated glazing can also be used for sidelites and backlites, mainly to improve safety and security.
