I am not talking just a spray on insulation, I meant that along with the r-19. Since the only thing between the insulation and the outside is some wood, I figured I would add a little more. I am going to go through all the corners with expanding foam to make sure there are no gaps to the inside. The temps here never reach outside of 30-100. It is rare that it gets to either extreme so I will probably just try only r-19. As for the floor, I am going to look into maybe putting down new floor and building a subframe on top of that and insulate in between.Originally Posted by jotay
For heating, I am going to be using an oil filled heater on a ranco to keep the temps to 80 and all my adult racks use 11" flexwatt for the hot side.
