I use plexiglass on the outside of the cage so there's no glare or reflection. I have it cut to size, I drill (carefully, I shattered a couple of pieces!) Small holes and use zipties to attach to my cages around the bottom half.
Help keeps humidity up, mist spray in!
Easy to untie, wash if necessary, and put back up
Looks really clean cause you can't really see it and its cut to fit
