so we moved over the summer (kind of a huge mistake but what can ya do?) my snakes are now in a room built in the basement. there is one wall in their room that is concrete, the other walls are fine as they arent against the foundation. i want to line the concrete wall with something to help keep the cold from coming off the concrete into their room. does anyone know what will keep heat in and cold out better? im torn between reflectix and polyshield.
