I guess what I want to know is why? One of the greatest things about keeping chams is the screen cage IMO. Lightweight, easy to clean, easy to see the animal. You don't get any of that "reptile smell", you don't have the nightmare of trying to clean an aquarium. No mineral buildup on the glass, etc. The best part is they're cheap, and super easy to build if you're DIY inclined.
I think people are far too obsessed with the concepts of keeping other reptiles. It seems to me as long as your normal room temperature is above 60 all the time, there is no real problem, the heat lamp takes care of the rest.
My enclosures have 3 screen sides (Top, Side, and Door) and 3 plastic sides (Back, Side, and Floor). It works great. The only reason I use the plastic back is to protect my walls from misting, and the plastic side is a divider between two enclosures
