There are many more options for stove pipe boots on metal buildings than there was since I built my quonset,back in 1992..including these hi-temp silicone boots..
Back then all they had were metal mostly,and rubber ones weren't up to handling the temps .
It does not take much for air intrusion to make a big difference..
After I noticed water pooling up in the bottom of the arches where they bolt to a U channel to fasten them to the foundation walls,I decided to drill 1/4" holes ,two close to the bottom each arch and the channel,so water could drain out..
The first winter after that,I noticed it took a lot longer to warm up in there using the wood stove,and it'd cool off a lot quicker,especially if it was windy..
At first I blamed the overhead door,and tried adding furring strips and weather stripping to seal that up better--it helped a lot,but I could still feel a chilly draft if it was windy--I noticed one day a beam of sunlight was shining in thru those holes I had drilled--and placing my hand near them,I could feel a blast of frigid air blowing in.
I added it up..20 arches,with 2 holes each drilled in each one..
40 holes X 1/4" =10" ,so it was equal to having a 10" hole in the walls..(if I did the math right!)...no wonder it was cold!..
I used waterproofing tape to cover the holes up in the winter..made an immediate noticeable difference..
The walk in door bottom has to have a large gap at the bottom due to an uneven slab that tends to heave up a bit in winter--I put a flap made of old inner tubing on the door to help kill the draft that gets under it,but something like conveyor belt would hold up a lot better--right now there isn't any rubber there..
