I'm wondering if anyone has tried to better insulate a Styrofoam incubator? I have a hovabator 1602n and would like to build a new one eventually but in the time being I'm wondering if something like foam board (pink foam) would work to make a box around the incubator? Has anyone tried anything to improve insulating these types of bators? Ours works good but only in a already warm room. In any room with doors and a/c vents open it can't get up to temperature. Thoughts?
