Swinging for Divorce…

I lived in Mo.37years and have built and/or had built probably at least a dozen pole barns and 2 indoor arenas one was 50 x 100 and other was 60 x 90. Pole builders like to out down a sheet of whats it called ? as a moisture barrier under the roof tin. Real thin like maybe 1/8 in. thick. Sorta thin foam looking material/ Of course, this is the bldg. goes up not after!

I agree a garage or even home can be built too air tight but hard to do suck with a pole barn! I had a guy back in Mo. that built his own home and he admitted he did too good a job and it was airtight and could have some condensation. I have never seen one that good ever! It only gets really cold here in S E Tx. a few times during the winter. Cold today, about 17 this A M and winds about 20 and I am glad we have no air leaks in the home (except the darn sliding patio door!) cause a heat pump is not good in cold!!!!
