Thread: Plexiglass windows?

Tweet

Check your State Inspection Law. Probably every state in the country requires safety glass for the front windshield, but may allow other forms for side windows. For instance the Model A wind wings are supposed to be tempered plate glass which is quite heavy and not safety glass and I suppose they would be grandfathered in on a restoration. My main message is that you want LEXAN, not plexiglass. Lexan is a bit more expensive than plexiglass but very nice material and very tough. Plexiglass will yellow in a year or two and the cut edges will be very ragged with a combination of melt from saw heat and the "frizzies" from the saw cut. I started with tempered glass for Model A wind wings (too heavy), went through horrible looking plexiglass and finally had some 3/16" thick LEXAN cut at the same glass shop. Finally after paying for the tempered glass and the horrible plexiglass the shop just made the Lexan wings for free in a sort of "I told you so and we are sorry for you while you learn." move. Anyway I would avoid plexiglass and I suppose any glass shop will be able to cut Lexan for you.

Lexan is a DuPont trademark for their polycarbonate. Polycarbonate is much more resistant to breaking and scratching than acrylic. Plexiglass is Rohm & Hass' trademarked name for acrylic.
