Tempered glass is a heavier type of glass that’s harder to break completely. It’s the kind that cracks, not shatters all the way. In terms of your home, you would find tempered glass in your bathroom, shower, or patio door. A better example is that most smartphones have tempered glass, which prevents it from shattering completely if you drop it. Laminated glass is similar. It’s also a toughed glass that doesn’t shatter but this one is different because it’s covered in a sheet of thin plastic. It also adds an extra layer of security on it.
