Bad vapour barrier?
I have a log home. The roof looks to be - 2X14 planks laid onto logs covered with tar paper, then another layer of planks and tar paper, then looks like 3/4 inch plywood more tar paper, and finally tin this all appears to be tied in with upright 2X12s about 12 inches high with insulation placed between them. The inside ceiling is covered with 3 inch tongue and grove and I can see that there is somewhere between 4 and 6 inches of insulation. The gable ends have same with maybe a little more insulation.
Here's the problem -- I have heat and/or vapour coming out the gables and on top of the ridge pole -- how do I seal it up?
1079 ReputationI don't know your Geo for "R" value but the 4 to 6 inch insult sounds to light to me. It would be the reason for heat going out the gables ends.
The area above the ceiling Needs to breath so moisture doesn't get trapped into the "attic" space.
Normally an "R" 30 or more should be above the ceiling, which would be 9" of insulation. If you do add insulation use unfaced over existing.
