Toughened Glass:
Toughened or tempered glass is a type of safety glass processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. Tempering puts the outer surfaces into compression and the inner surfaces into tension.
This glass is able to carry immense loads due to this. However if this glass is stuck with a solid sharp point it will shatter into hundreds of little glass diamonds (as apposed to big sharp shards), this is to prevent and cutting/injuries and is the same glass used in cars windscreens and car windows.
Safety/Laminated Glass:
Laminated glass is a type of safety glass that holds together when shattered. In the event of breaking, it is held in place by an interlayer, typically of polyvinyl butyral (PVB) or ethylene-vinyl acetate (EVA), between its two or more layers of glass.
This glass is used as a precautionary measure against potential burglars/thieves, as the process of breaking and getting though it is extremely difficult/loud and time consuming.
Obscure Glass
Obscure glass has become increasingly popular among architects, interior designers and homeowners. When properly installed, the product can provide a number of aesthetic and practical benefits. So what is obscure glass, and why is it to your advantage to use it?
What is Obscure Glass?
There are several varieties of obscure glass, but in general it is any type of rolled glass that has a pattern embedded into its surface. Patterns can vary, and people typically use the glass as a form of decoration. Other types of obscure glass include painted and laminated glass.
Practical Uses for Obscure Glass
Though it is primarily used as a form of decoration, the glass is also used by window manufacturers. Obscure windows are ideal for the exterior of your home because they provide privacy and security. People will have a difficult time peaking into your home after you install image-distorting glass. If you still want to be able to see outside, then you should purchase reflective windows, another member of the obscure glass family. These windows allow you to see outside while simultaneously preventing people from looking in.
