I want to caulk and foam all joints in my framing prior to hanging drywall. Is there a difference in latex caulking and is there a best one when it comes to providing an airtight seal for air barrier? I will be hanging glued and screwed OSB on the interior side of the studs for stiffening an old house, will the same caulk and or gaskets be fine to install the OSB as it would on drywall.
When construction adhesive is used on the drywall or OSB, will that effectively act as an air seal on the faces of the framing or should one use gaskets and if so, what is recommended. I have used Denarco gaskets years ago, are these still advisable? Recommendations of sealants that have good value and performance would be great.
Lastly, when a INSULATED service cavity is used on the interior of the the sealed exterior walls ( mine have a OSB layer to stiffen a squeaky house, should the Intello or such be against the OSB and the service cavity built on top of it or should the smart wrap be directly behind drywall.

Thanks for all past help.
