BP tank set up + accessories

[Bogertophis]

Thanks for your reply Snowman. I have not insulated the outside of the aquarium. Any ideas what I should use? Going to try the foil thing now.

Many things can be used to insulate a tank- some have used sheets of styro-foam, cut to fit & taped on- (not very attractive, admittedly, but effective- & it depends on how cold your house is).
You can use sheet cork (or cork tiles), corrugated cardboard, poster board (comes in white or black, with foam core, but easy to cut & deal with), thin plywood that's cut to fit, or even the foil-bubbles that ppl put on hot water heaters. For insulation to work, it's all about the air spaces that it traps.

If you want this to look nicer, install scenery on the back & sides of the tank first, then your insulation won't even be seen. You can insulate under the tank too, but leave breathing room for the UTH, if you're using one, & you can even insulate partway up the front, just leaving a large "picture window"- it's all up to you. Snakes enjoy privacy anyway, but for health & well-being, I personally like to know what's going on in all my tanks. You want to be able to see prey that's uneaten or feces that need a spot clean without opening it up to let the winter chill in.
