so i ordered frozen rats from online and the package came insulated with fiberglass. the length used in the package is exactly as long as my tank, if a bit shorter. i want to repurpose it to surround my bp's enclosure for extra insulation. i was thinking of just sandwiching in between two pieces of cardboard and then attaching the contraption to the tank. it'll look ugly, but hopefully would be functional. just wondering if there's any advice on how to do this better, or warnings against doing this?
