Hello No problems I am still learning ask away.
I got Extra Large Marine Roll Closed Cell Neoprene Rubber with Adhesive at home depo. I noticed a little change in temp if I was you I would go with something better. I live in New Hampshire in an old house so it is super drafty in here. I keep blankets on her cage I plan on getting some thing else.
I would go with what Bogertophis is saying. The stuff I bough was cheap and easy to find in a pinch.
Ask away I learn from everyone else.
