I’d be interested to know too. Since the substrate I use isnt the warmest I usually put something like fitch or clean & cozy in the whole nest area then put extra tissue in, it keeps them warmer. Last winter my house got exceptionally cold when the heating broke for a while, so I did line the back of my detolf with cardboard sheets (on the outside) but not sure how much of a difference that made.
