Siding Replacement Questions
I'm gathering the materials now to do my siding install, I think I have the layout like I want it, but want to verify that everything looks okay. My biggest concern is that I have found some threads on here talking about Hardie not warrantying 7" reveal blind-nailed lap siding, though I have read every install pdf on their website for my zone (HZ10) and cannot find anything that says this voids the warranty. I know they've updated the install instructions as of November 2012, but I don't remember them ever mentioning anything smaller than 8", and even then it was only a recommendation, requirements didn't start until you got to the 12" boards (iirc)
I made a sketchup drawing of my plan, it will be as such. New insulation (still deciding between Roxul and fiberglass) with 1/2"-5/8" construction grade plywood sheathing. Perforated radiant barrier as house wrap with 1"x2" furring strips to allow for 3/4" air space requirement for radiant barrier, while providing enough room for nailing butt joints. Finally, 8 1/4" HardiLap siding with 1 1/4" overlap, blind nailed with hot dipped galvanized 2" nails and strips of roofing felt at the butt joints.
