Barry,
I couldn't tell you any exact name of the plastic I used for panels. I was just looking around for ideas like you are and got the idea of checking out a place that sold plastic sheet along with other plastic products. They also fabricated large orders of plastic items like those clear plastic display holders you see on the tops of counters that have things like advertising brochures in them - actually about anything in plastic you wanted to order made to your specs. It wasn't a retail place - more of a wholesale and fabricating place, but I walked in and asked to look at the kinds of plastic sheet they sold. It turned out they had all kinds and were completely happy to sell me anything I wanted in any quantity. Sometimes it pays to think out of the box, because you end up developing resources that work for lots of different needs. Just start looking & checking around & good luck.
