The enclosure for my BP is a 40G breeder tank, all glass. I'm finding it difficult to maintain an ambient temperature inside the vivarium over 80 degrees Fahrenheit. I was recommended to cover three of the walls with some sort of paper to hold in some of the heat, but I'm not really interested in taping printer paper, which is really all I have, to the sides of my terrarium. I looked into the aquarium paper backgrounds, but those are ridiculously expensive for what they are and it's difficult to find both a design I liked the correct size, not to mention that only covers the rear wall.

So, I started finding these cork planks on various herp supply websites and really thought they would look exceptionally natural as a background and walling. I believe they could provide a good spot to rub against for shedding. What do you all think? If I use them, I doubt I could pressure fit them in, so I'd have to use silicon sealant. With monthly cleanings a necessity, is there any way to remove the silicon sealant that's safe for my BP since the dissolvent would come into contact with the walling? Also, how do you all think I could mount my plastic plants to the walling? With the glass I could just stick them on and leave them, but with these there's no sticking.

I'd really like to use the cork planks as an internal walling for my BP, but I'd like to hear your comments. The more the perspectives and comments, the more rounded my idea becomes.

Thanks!
