Rain screen with lap siding
I looked around on this site and Google but could not find a clear answer.
Currently my double stud wall assembly has the exterior 2×6 at 24″ OC followed by 2″ on ConfortBoard and by a rainscreen. We plan on installing LP Smartsiding Lap siding which requires 1-1/2″ of nail penetration for both their 3/8 (16″ OC) and 7/16 (24″ OC). I have been told their 7/16 is difficult to source which is leading me to likely go with 16″ OC for that exterior siding.
Now my question, if the siding requires 1-1/2 nail penetration, I am forced to use 2×3 or 2×4 with 5 inches fastener. Will such a big rainscreen gap (1-1/2) introduce other issues down the road or is that fine?
