As you move to a new house in Florida, you might be unaware of everything the house has to offer. As we live in Florida, it is a good idea to know what windows you have. It may be hard to see the difference between regular glass and impact glass at first, but there are things done to reveal the difference. Usually, you can find a permanent mark in the corner of the glass that shows the supplier, where it was fabricated, the thickness of glass, and when it was manufactured. If the mark isn’t in the corner then there I another way. Impact glass is made with two frames of glass, which both give a reflection. By bringing an object towards the window, if you see two reflections, then it is an impact window.
