Polycrylic, actually, I have used and liked for furniture. Ultimately, I found cleaning things to be far simpler when we bought a triple-decker (three terraria) built by a breeder. His design was painfully heavy, so, that part could be improved upon, but, he glassed the inside of the terraria. I.e. wooden shell, lined with glass, siliconed into place.
The glass is heavy, though. If just for snakes, acrylic panels could work better. Certainly lighter, and I find it to be less susceptible to craking. We used some of Big Apple's heat rope under a terrarium, with a rheostat and plenty of ventilation. We let it get too warm (not warm enough to harm the snake inside, but...) and the glass split. Now, we're replacing the glass, bit by bit, with acrylic panels... Cleanup is a breeze... Snake poops, quick wipe with paper towel, spritz of desinfectant, water, squeegee, and the snake goes back in.
