2×4 walls, R-13 Kraft, Zip R-9, probably metal or Hardi siding?
Zone 6A. 2×4 walls of older home. No poly or anything of that nature.
The company I hired is owned by a local guy, I found out the hard way he has a history of quitting mid work and defrauding people. So my home is currently protected by just zip sheathing, 2 walls still with original siding . My plans of exterior eps & rainscreen were ruined. No other company here will do exterior insulation.
One reputable company will tear out and rebuild with Zip R and that’s my only option for additional insulation. (Even reputable companies think I’m talking witchcraft when I ask about air sealing foundation to sill and etc 🙄 so I’ll finish the airsealing personally) I have two options 1: reside oldschool way without any exterior insulation. 2: resheath with Zip R9 then side with a metal siding or hardi plank. No furred out rainscreen as that’s witchcraft too. And hiring on helpers or friends to do my own exterior insulation before the company resides isnt feasible either.
I’m torn because there is such disagreement about Zip R in cold climates and mold concerns. And I’m going to assume the Zip R wouldnt be installed picture perfect? Maybe it would be safer for me to reside oldschool and then do something on the interior instead like foam board over my studs and then drywall? (Hate to lose the space & do all that work personally but I would.)
I’m living here forever and then my daughter will own this home, so I’m not concerned about resale values- I’m concerned about upgrading for comfort & lower heating Bill’s.
1: oldschool- siding on sheathing.
2: Zip R9 sheathing and siding.
