What is laminated glass?
Laminated glass is a type of safety glass that is composed of two or more layers of glass bonded together by a layer of polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA) resin. The outer layers of the glass can be made of tempered glass for added strength.
Laminated glass is designed to increase safety in case of breakage, as the PVB or EVA layer holds the broken glass pieces together, preventing them from shattering and causing harm. The layer also helps reduce noise transmission and blocks ultraviolet (UV) rays.
Here are some key characteristics of laminated glass:
- It is resistant to impact, penetration, and forced entry
- It maintains its integrity when shattered
- It reduces the risk of injury from broken glass
- It can be used in a variety of applications, including windows, doors, skylights, and automotive windshields
What is tempered glass?
Tempered glass is a type of safety glass that is processed by controlled thermal or chemical treatments. It is also referred to as toughened glass or tempered safety glass.
- Tempered glass is stronger and more durable than standard glass, making it an ideal choice for applications where safety is a concern.
- Tempering glass involves heating the glass to a very high temperature (around 650°C) and then rapidly cooling it with jets of air.
- This process causes the glass to contract and become compressed, which gives it a surface tensile strength of around 10,000 psi, approximately four times that of normal annealed glass.
Tempered glass is commonly used in a variety of applications where safety is a concern. Some examples include:
- Automotive windows – Tempered glass is used in automotive windows because it is more resistant to impact and shattering.
- Shower doors – Tempered glass is used in shower doors because it is safer in case it breaks, it only breaks into small pieces which are less sharp compared to regular glass.
- Tabletops – Tempered glass is used in tabletops because it is more resistant to scratches and breaks.
It is important to note that while tempered glass is stronger and more durable than standard glass, it is not indestructible. Extreme impacts or scratches can still cause tempered glass to break or shatter.
| Properties of Tempered Glass | Values |
|---|---|
| Surface compressive stress | 69 MPa (10,000 psi) or higher |
| Bending strength | not less than 97 MPa (14,100 psi) |
| Shattered pattern | produces small, square pieces with relatively dull edges |
Overall, tempered glass is an excellent choice for any application where safety is a concern. Its increased strength and durability make it a smart investment for anyone looking to add an extra layer of protection to their project or product.
Differences between laminated and tempered glass
Both laminated and tempered glass are commonly used in construction and architectural designs, but they have distinct differences in their properties and applications.
- Lamination Process: Laminated glass is made by sandwiching a layer of polyvinyl butyral (PVB) between two or more sheets of glass, which are then bonded together under heat and pressure. In contrast, tempered glass is produced by heating the glass to a high temperature and then cooling it rapidly, resulting in increased strength and durability.
- Strength: Tempered glass is about five times stronger than standard annealed glass and can withstand sudden changes in temperature and pressure. Laminated glass, on the other hand, is made to prevent shattering and splintering upon impact, making it ideal for use in safety applications.
