Now your rolling. :thumbsup:
That's a good insulation spec. Usually (from what I've seen) the spray guy's give you a touch more than you spec'ed, but make sure you check it where it may look a little thin. The reason for this is I've always heard it takes 2" of (
closed cell) foam to avoid a dew point issue*. You want the dew point in the foam not the cellulose or f/g blow in to avoid moisture problems in your wall. The foam will stop all air infiltration and that's huge in itself.
Some, (I suspect with poorly insulated homes) say a house can be "too tight". This is partially correct, but that's covered nowadays with a HRV or ERV. That's a "heat recovery ventilator" or a "energy... rv". Beside's the naturally occurring moisture, cooking dinner, laundry & just people add greatly to this humidity in your home. I am no expert on this topic but these are things that I've picked up over the years being on res. building jobs and this is just for your "inquiring mind" as your in this up to your neck right now. Ask & read about this from where ever you can. I am not sending any great warning here with this, just trying to make you aware of a possible additional step (adding a HRV) that you may think about taking while your still in the building process. These units are not very expensive and it's installation looks very straight forward. Iirc you are going radiant and a HRV may not be compatible with out ductwork, but are you putting in a/c?
Lastly this whole (moisture) post of mine may be n/a to Idaho. Every time I'm out in that area, after a few days I need to literally snort water into my now thoroughly dried out east coast nose.:laughing: I definitely have low humidity envy.
*this may be climate dependent. ?
