I have a small lean-to attached to the side of the house. I will be expanding it this spring to make room for a growing collection. Right now I've got mostly Cats, Onc, and a few other things I'm playing with...Stan, Crths and Zygo's. Any suggestions for glazing material? I have been looking at everything but still have not decided on one thing yet. Right now it's rippled/corragated fiberglass panels.
