Sealing cedar wall shingles and air infiltration
Hi. I’m building a house in CA and it’s a craftsman style, and will be using some double dipped cedar shingles as the siding. My GC is planning on using Tyvek as a house wrap, and then a second layer of asphalt saturated paper on top of the Tyvek and nailing the shingles to that. I think it’s planniong on galvanized or steel nails to fastening the shingles
I am worried about all those holes causing a problem with air infiltration through the sides of the house. Is that a problem?
My GC has done a fair number of high end homes here with this 2 layer approach and never had a problem with water infiltration or rot (we don’t get a ton of rain here in 94062), but didn’t know the answer on the air infiltration issue.
