Even though glass may seem like the less important detail while choosing a window. It has an important effect on the overall look and warmth of your home. There are plenty of factors to consider before choosing the glass for your windows. Like, location, surrounding, security, daylight and more. There are many reasons why security glasses like tempered or laminated glass would be a good fit for your home.

What is toughened or tempered glass?

Tempered or toughened glass is standard glass that is processed under controlled heat to toughen it and make it stronger. It is a type of safety glass. Compared to regular glass, it is stronger, safer and extremely durable. When broken it breaks into smaller cubes reducing the risk of getting cut. It is built to withstand extreme temperatures.

What is laminated glass?

Two or more panes of glasses are bonded together by an interlayer of resin, to form a single sheet, the process is done under high temperature and pressure. In most laminated glasses the interlayer material is Polyvinyl Butyral (PVB). There are other interlayer materials like Ethylene Vinyl Acetate (EVA) and Thermoplastic Polyurethane (TPU). When there is a breakage, laminated glass does not shatter and holds together, reducing the risk of injury.

Laminated glass can be made from; 

  • Annealed (float) glass,
  • Toughened glass: It is called toughened laminated glass. It increases safety by holding the shattered pieces in place when broken.
  • Heat strengthened,
  • Wired glass.

Laminated glass applications 

Laminated glass is used in many applications such as: 

  • Windows and doors, 
  • Curtain walls,

Laminated Glass Pros and Cons

Laminated glass is a type of safety glass composed of multiple sheets bonded together. The layers are then secured together using an interlayer product such as polyvinyl butyral (PVB).

This ensures that if one layer breaks, there is still another that will hold it together. This prevents large shards from flying out and causing injuries.

Cost

Laminated Glass is a type of safety glass commonly used in skylight glazing and automobile windshields. It also finds application in hurricane-prone regions where buildings must be resistant to the elements.

It consists of two pieces of tempered or regular glass sandwiched together with a clear plastic film called an interlayer, which helps hold them together during use.

In the manufacturing process, two layers of glass are heated and melted together to form a laminated product. Under pressure, this creates an object stronger than regular glass.
