Why is wired glass weaker than unwired glass?
Despite this belief, wired glass is actually weaker than unwired glass due to the incursions of the wire into the structure of the glass. Wired glass often may cause heightened injury in comparison to unwired glass, as the wire amplifies the irregularity of any fractures.
What is toughened glass?
Toughened glass is processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. Tempering, by design, creates balanced internal stresses which causes the glass sheet, when broken, to crumble into small granular chunks of similar size and shape instead of splintering into random, jagged shards.
Why is wired glass used in elevators?

The result is a glass much stronger than normal, capable of withstanding nearly four times the amount of force needed to break untreated glass. In addition, when tempered glass does break it shatters into small pebble-like granules, rather than sharp shards.
How thick is laminated glass?
For example, laminated glass in automobiles is usually about 6.5 millimeters thick, while the kind used in airplanes can be three times as thick. One of the main advantages of laminated glass centers on its bonding agent. The PVB interlayer serves to hold the glass together on impact, causing it to crack but not shatter.

This is commonly used for smartphone screens and aircraft windows. This type of glass is often laminated to improve its strength and safety characteristics.
What is acrylic glass?
Acrylic glass is not glass but is rather a translucent plastic that can be used in place of glass. This is used for specialized applications where the brittleness of traditional glass makes it a poor choice such as the window of a large aquarium. Acrylic glass is flammable and was a factor in a 1973 fire known as the Summerland disaster that took the lives of 50 people. Acrylic glass is often used in marine environments such as the windows of yachts.
Is Tempered Glass heat resistant?
This results in a strong glass that is reasonably heat resistant. Tempered glass is designed to completely break into small chunks that are thought to be less dangerous than large shards of glass. This makes it a poor choice for security glass as it can be easily and completely broken with a small puncture wound.

There are two main types of safety glass, toughened and laminated safety glass. Both are produced using strengthening techniques and both are proudly manufactured and provided by Magic Glass.
What is laminated glass?
Laminated glass, on the other hand, is manufactured by placing a layer of polyvinyl butyral (PVB) between multiple panes of glass and fusing the entire unit together using heat and pressure. The interlayer of PVB holds the glass in place, preventing the unit from shattering upon impact. Furthermore, by varying the thickness and colour of the PVB interlayer, laminated glass can be used to minimise the transmission of solar energy, reduce UV radiation and control glare.
How does toughened glass work?
Toughened glass (also known as tempered glass) is strengthened by speeding up the rate in which it is cooled. This process increases the tensile strength of the glass, making it less susceptible to breakage caused by heat, wind and impact. When toughened glass breaks, it shatters into small cubes, minimising the likelihood of injury upon breakage. Toughened glass cannot be cut or drilled, however it can still shatter making it less secure than laminated glass.
