I see that you have framed up with ?1x2 or 1x3 but what are you nailing them onto? The bus wall? I see that you have insulated as well. Are there photos of the before you framed and insulated? Thanks, M

Hi! Sorry I’m not on here very often anymore we screwed the 1X3s directly to the inner wall. We didn’t remove the original inner wall as most do. We didn’t mind losing the inch and half by keeping them. Hope that helps!
