All right all you builders, I have a question concerning sheeting the inside walls of my shop. As most of you know, I have 2x6's laid flat so as to give me 5.5" between the outside sheeting to the inside of the walls. I have 7/16 OSB covered with Tyvek then Hardi-plank siding on the outside of the walls. My question is this. If I just put OSB on the inside of the walls with out putting insulation in, am I creating a situation where I will have a moisture problem in this 5.5" space in the wall due to temperature differences inside and outside the wall? I don't mind buying the insulation if I have to but I don't plan on insulating the 26ft high vaulted ceiling so the wall insulation will be pretty much a waste as far as trying to keep the place heated. If I did insulate the ceiling for warmth, the amount of heat need for that tall of area would be massive cost wise as well as time wise to get it to a reasonable temp down low at floor level. One option would be to build a false ceiling so to speak and blow in insulation at the 14 ft level?????? The problem with this is that I would take away the large amount of storage available in loft areas. Any ideas? I live in SW Washington state, it never gets real cold for too long like in other locations in the east or farther north. Thanks for any help or ideas.
