When building a Super Insulated wood framed house, should the framing members and sheathing be caulked with construction adhesive or acoustical sealant, or both?

I have read a number of articles on "Super-Insulated" houses where the authors underline the importance of air-sealing the building component joints & seams with "caulking" but they don't say which to use where.

Does it matter?

Thanks.

Not constrction adhesive; that stuff is to hold things together, but that is what framing nails do. For air sealing, you want something that seals any cracks between members against air flow. For that, you want a material that never hardens, but can move slowly as the wood components change shape ever so slightly over time, from loads or seasonal moisture adsorption/desorption. "Acoustical sealant" has been used for this, because it works so well. I first saw Tremco's product mentioned for the purpose, although some have called it "black death," for its taking so long to wear off the fingers if it got on there! There are other equally effective products out there now, with reportedly better properties. OSI makes a product for this purpose.

Construction adhesive remains sufficiently flexible over time that it can be used for air sealing, and it adds some structural rigidity (nail spacing requirements notwithstanding). It adds some VOC to the building, which may be an indoor air quality issue for the chemically sensitive, but for most it's not an issue, since the sheathing & framing are fairly isolated from the interior air, and the diffusion rates low.

Acoustical sealants are still the "gold-standard" for air sealing though.

Thanks people - it's acoustical sealant all the way!
