Ok, I guess you learn something new every day. We have a large screen porch....about 16 X 16 with 13 screen panels about 3 ft wide by 5 feet tall. Anyway, I put in some cheap rolled plastic over the screens during the winter months to cut down on winds and drifting snow into the screen porch. I was looking to get some thin plexiglass panels made, aand it seems like the cost of this would be appx $80-$100 for each panel...nothing nice....thin material - clear finish. Anyway, why is this stuff so expensive? Anyone use anything else?
