I have searched and I bet this has come up a lot. Sorry if I am beating a dead bush, I am looking at building my dragon an new viv, right now she is a glass aquarium, right size for her, thought the one I am looking to build is a double decker and I am guess most people go with Plex-glass or plastic clear sheet, but would mesh work just as good, say like on a screen door since they like to climb?
The whole viv being screen? I wouldnt...it doesnt allow heat to stay in the enclosure, and your dragon could get a nail caught and ripped off if trying to jump down..
Mesh would probably raise your heating requirements. It may also be a bit hazardous should your little one get snagged in the mesh climbing around on it.
Plexiglass and acrylic is not really durable, I have been using plexi for my doors and it's horribly scratched up.
I used all three. The top of my viv and enclosed by a screen top (hidden by a canopy), the front doors are made of glass, as I did research before building and read the horror stories about ugly windows, and the bottom windows are made of plexi but the are more part of a cabinet and not the viv.
