    Just so you know, the installation of your I joist floors is dependent upon the manufactures installation instructions as most components in homes are now so don't get all hung up on code.

    And yes, your wall are most likely going to be 24 on center, nothing to worry about.

    If I was ambitious I could post a thermal image photo of a cold exterior wall to show you the thermal bridge your wall studs have.

    Nope

    Nailed straight to sheathing/housewrap

    I'd say if the rain screen works in the rainforest climate you're in it should do fine here lol

    OP,
    I am a builder in Pa and the reason for stud and TJI (your type of floor joists) spacing at 19.2 " OC is to save money, in my area at least. 19.2" OC is one less stud, joist... per 8'. The TJI joists are not cheap. My only concern with this spacing is the floor joist and the sub floor installed on them. 3/4" toungue and groove plywood would be fine but OSB... I have my doubts.

    Yes, once again OSB is cheaper than CDX ply.

    Getting back to the question about how they are going to get R50 in your vault , it looks like they designed the trusses with a substantially raised heel to allow for a deeper insulation mass down to the wall plates , assuming that continues throughout the truss system

    Bed rug, ARE bed top, Weathertechs. Little goodies here and there!
    16" 2x6 OC here in IA. When my house was built, wet blown in insulation. It's the bomb. Our house is twice the size easily of our previous one, yet the utilities are about the same if not a little lower. Keep in mind the previous was built in 70 and 16" on center 2x4. That house needed a foam injection badly. Glad I'm out.
    Enjoy watching it build. Try not to rush them as the finish quality could suffer.

    In that pic there are a couple frieze blocks left out , most likely running baffles into the soffit through there

    24" OC

    19.2" is usually only used in engineered floor systems which is what that poster was commenting on
