The rack can maintain a 77-80 ambient with the door closed. It definitely doesn't drop below 75. I haven't had an RI yet.

I keep the door open during the day and non-winter months.

The actual purpose of the door was to keep away unwanted eyes and my ferrets out during their play time. But it turned out better than I expected for retaining heat. haha.
Oh wow that's awesome. What is the door made out of? And what is your rack made out of?
