Only if that doesn't do it, do you close the vents. You'll probably also need to add the heat mat on the warm side to get temps up in the warm side hide. I looked at your last post requesting assistance with heating. Is the ambient room temp still 65 degrees? If so, that's why you have to work so hard to get temps up.
Yeah I was really thinking that with the insulating foam I used for the background and the sides plus the thick substrate and the top! Wich has aluminium foil and some towels on top to help insulate, the only part left is the front glass for the heat to escape.
