120 year old uninsulated home siding retrofit
LP Smartside 76 series 8” 7/16” lap siding has been purchased by our contractor and now I am finalizing details.
Please review for compliance, efficiency and best practices and fill in my blanks. 😉 We plan to live here for a long long time and want to make sure we do it right.
Strip cedar shakes and old lap to 3/4″ diagonal bracing or studs if bracing is rotten.
Replace rotten diagonal bracing with __?__.
Install tyvek as an air barrier
Install 1.5″ R6 Roxul Comfortboard with 1×4 strapping screwed 1.5″ into studs 16″ OC
Install lap siding with 2 nails per board through strapping16″ OC
Windows are replaced with replacements as innies (see pic) and will be aluminum wrapped but not sure about proper flashing.
I also have questions about the following;
Does Roxul’s comfortboard need a perforated galvanized u-channel on its base?
How to I air seal to that rock foundation?
