That is a valid concern. Without a control on this particular heat pad it reaches 115 degrees and could effect the finish on wood. I made a pad using aluminum foil for the heat pad to sit on. Make the pad by loosely folding the foil over a few times and you have an excellent heat barrier.

Just be careful as I have seen them submerse under the aspen and be in direct contact with the glass
