Expense was the first consideration. It was much cheaper to buy the rigid foam than to frame up a 13'x24'x7'7" room. I am not going to run this wood as vertical studs but horizontally across the walls. I can space out the screws better that way. All I need are 3 runs of boards top, middle, and bottom, place the foam on those boards, then nail the t1-11 securely. Or am I off base here in my thinking? This is my first attempt to do work like this I was estimating a total of 38 boards to complete the room.
