There are two glass types available to protect against the risk of injury. The choice is made-depending on where and how the glazing is being used.
Toughened safety glass has undergone a heat treatment to increase its overall strength. Generally it is 5 times stronger than normal glass. To give an example a piece of 8mm toughened glass can withstand the impact of a 0.5kg steel ball dropped from 2 metres. If the glass does break, it breaks safely into thousands of tiny pieces with dull, safe edges.
Laminated safety glass comprises two pieces of glass held together by one or several plastic films like a glass sandwich! In the effect of breakage or impact, these films hold the glass in place. The glass still breaks into pieces, but they remain adhered to the film(s).
