Choosing a Cold-Climate Wall Assembly
I’m hoping to have some renovations done to my house soon. It was built in 1953 and has no insulation in the walls and balloon framed. Its a combination of drywall and plaster and has cedar shake siding which needs some work or replacement with another siding product. I’m in climate zone 5a.
Scenario 1 : Blow in dense packed cellulose, add WRB, exterior insulation and siding.
Scenario 2 : Gut interior drywall and create a wall assembly of drywall, smart membrane, mineral wool, sheathing, WRB, exterior insulation and siding.
Will both those wall assemblies work?
Will wall assembly 1 be ok with no interior air barrier?
Is the dense packed cellulose going to work anywhere near as well as gutting the interior?
Thanks for your respoonses
