I’m building a new shooting house in the next week or two and am looking at making sliding windows by making a frame from 2x2 and cutting two tracks on top and bottom for 4 pieces of glass that I can slide to open. I was going to do plexiglass because I see most people use it and I figured it was cheaper. I went and looked at prices yesterday and was surprised that glass was cheaper than plexiglass. I would think glass would be better for the lack of scratching easily and yellowing. Am I missing something here or is glass the better option?

Any other ideas on how to make cheap sliding windows besides my 2x2 frame idea?
