Metal?

Yes but my worry is that heat isnt actually touching the back of the tub really.

have you measured the back of the tub to find out what the temps in the tubs actually are? this has been my concern

Yes the heat is making its way into the tub, there is about a 6deg difference from front to back

Do they offer a rack with belly heat? Since heat travels vertically (rises) and not horizontally, I'd be concerned using that style myself. I personally prefer belly heat for that reason. And, I don't have the luxury of closing off a room to keep a room in the 80's.

Eric said he could make one with belly heat but would be more expensive. You can email him off the Sentec Caging site.

Eric can also install pvc siding into the racks also to make them enclosed.
