Is Security Glass A Great Investment? Does It Work?

Glass leaves vulnerable points in your building for intruders to gain entry, and when glass is broken, the chance of injury is very high.

Security glass also called “safety glass”, is glass that has been treated to be safer than standard glass. Security glass for windows is used to help protect against break-ins, vandalism, accidents, and natural disasters. Some types of security film can also reduce heat to a building or minimize the damaging effects of ultraviolet rays.

So how is security glass "safer" than regular/standard glass?

Well, security glass is treated with heat to be:

  1. More resistant to breakage
  2. Safer when broken (doesn’t break with jagged edges)

What Are The Different Types Of Security Glass

You can choose between 2 different types of safety glass: tempered and laminated.

Tempered Glass

Also called “toughened glass”, tempered glass has been heat-treated (heated to about 1200°F and then cooled quickly) to become stronger and more resistant to breakage. When tempered glass does break, it crumbles into small chunks instead of shattering into shards like plate glass does.

Tempered glass is often used on:

  • Computer monitors
  • Refrigerator shelves
  • Oven and microwave doors
  • Automobile passenger windows

Laminated Glass

Laminated glass is essentially a glass sandwich with a resin glue film in the middle to prevent the glass from breaking into sharp pieces. When laminated glass breaks, the glass adheres to the film, creating the distinct “spider web” pattern you’d recognize on a broken car windshield (most car windshields are made of laminated glass).

Laminated glass is also commonly used on:

  • Shower doors/enclosures
  • Storefront doors/windows
  • Greenhouse windows
  • Office walls/partitions

Part of a great home security system in addition to security glass is installing glass break sensors on safety glass windows. This will trigger your security alarm as soon as the glass cracks—which could be before the intruder even makes it through the glass.
