PT Sill Plate Shrinkage
Another rookie framing question:
How is the eventual shrinkage of high moisture content PT sill plates typically dealt with?
My PT 2x6s are at 35-45% MC, and are ~5 3/4″-5 7/8 wide. If I flush the 18% MC, 5 1/2″ studs on to the outside of the sill plate at the exterior, and then sheath the exterior, I would expect that a gap of 1/8″ to 3/16″ would open up between the sill plate and sheathing once the PT has dried. Or do the nails not pull and the sheathing is able to flex enough in that short distance?
The only counter measure that I could come up with, outside of drying the PT, is to apply heavy sealant at that particular joint…and then just rely on my other sill detailing for any gaps that open up.
