So upon getting my over-the-garage door storage built in my garage, one of the support beams had a meeting with the front window of my VMC40. Didn’t seem like it took much to shatter it so it is probably best to replace them anyways. I’m going to buy some Lexan to replace them. What thickness is the Lexan from the factory? I don’t want to go off of the Windows I’m replacing because I don’t know if they are the “correct” thickness.
