The peg board is to keep Buttons away from the screens covering the Vents. I like the tilt for the area that it gives me in the cage that Buttons does not have access to (room for lights, electrical plugs, lines for a Humidifier), and still remains high enough that the peg board does not detract from the looks of the cage.

As for heating it, I thim I will put a half inch base around the bottom so there is just enough room for a heat pad, and air flow.
