There have been a bunch of threads on this general topic but none really addresses my issue. My garage is unfinished, and so the ventilation at the base of the rafters and the turbine vent near the crest of the roof are exposed. My question is, shy of "finishing" the garage, which would leave me with less head room then I'd like and the loss of the trusses for storage what can I do about these vents. I'd like to run craft paper backed insulation everywhere I can get to, but if I have a gaping hole at the highest point in the roof wont all the hot air simply drift out rendering whatever heating solution I employ basically useless?
I know that letting the moisture escape is not just a good idea, but absolutely necessary to avoid rot and mold, could I simply rig up some kind of close-able cover that I would leave open whenever I wasn't running the heater in the garage? It doesn't get "that" cold where I live but cold enough that it's unpleasant and I'd rather not try and heat up "the world."
