Roxul and cladding help
I need some help. I’m trying to build a house with 2×6 construction, zip sheathing with fast flash, 2″ of roxul comfortboard, 2×4 furring strips and lp smartside. I planned on using heco fasteners. First of all, is this an efficient wall assembly? I’m here in MO and there are no builders familiar with exterior insulation. I’m getting frustrated as everyone is trying to talk me out of using it. Tilt up construction is common here so has anybody successfully done this in a tilt up fashion or should I have the framers do the sheathing and try to find another trade for roxul and cladding? Videos of this would be appreciated. I’ve watched many videos online but none with this sequence.
Would I be better off using a different cladding, say stucco to eliminate the furring strips and window bucks?
Finally, does anybody have a good suggestion for window buck besides plywood? I’ve seen therma buck but don’t want something soaked in chemicals. Alpen can factory attach 3.25″ extensions but for this setup I think I would need at least 4.25″.
Your help is always appreciated. Thanks josh
