Chips: When you follow a vehicle too closely and a pebble or piece of debris hits your windshield, a chip in the glass can result. Chips almost always occur on the outer layer of the front windscreen. The screen – or windshield – is comprised of laminated glass and is actually several panes of glass separated by a layer of plastic. This process makes the auto glass difficult to shatter. So, when that tiny rock or tin can flies up and hits your windscreen, tiny pieces of glass will flake off, and that’s when you get your chip. 2. Cracks: When we speak of auto glass cracks, most of the time, we are referring to the laminated glass that makes up your front windscreen. However, any of your auto glass panes can crack, including the tempered glass that makes up your rear and side windows.
