wood works good too, and its a natural insulator.

I use alumonum foil, shiny side down. helps the heat and humidity stay in my anole tanks, although it's none too pretty

are you using any heaters? a low heat source under the water will increase humidity. Substrate matter that will hold moisture also helps....you have sponge which should work amazingly. What humidity do you have at the moment?

As many have said....decreasing air flow will sort the humidity...but remember you still want some ventilation...you will get this from the door gap though. I also know which cage you ase using.
