we just finished a week of kicking about in WA state. it was raining a good part of the time, quite heavily. the temps were cold enough, mid 40s to promote furnace use. as a result, we had quite a bit of moisture build up on the windows.
we don't have those nifty plastic caps on the fantastic fan openings so could not leave them open as they would just close down with the rain coming down. we do use the vent over the stove when cooking.
i am now wondering if it would be advisable to simply open the vents in the toilet and shower areas, no fans going, as they do have caps which would keep the rain from entering.
your thoughts on how to about controlling moisture buildup are appreciated.
