Has anyone used insulation (thinking foam sheets) behind their rack to keep the heat in better? My house is old and drafty, and I'm wondering if the walls will just act as a giant heat sink.
Don't have the rack set up yet, but it will be going in a not so warm room., so I want to do all I can to minimize wasted heat and electricity.
I'm trying to convince my wife that we should move our daughter out of her bedroom (it's the warmest one in the house) so we can put snakes in there, but she doesn't seem to be going for it.
