TJI stud bays vs double stud wall
I would like to hear from the community comparing and contrasting the use of 12″ TJI studs to a 12″ double stud wall (not staggered). Assume (for the sake of this discussion) that the TJI studs will pass code in your locale. My main questions are as follows:
Is the thermal bridging from the OSB web significant when compared to a double stud wall?
Does the gap between 2×4’s create a difficult insulating scheme compared to individual cavities when using dense-pack cellulose?
Would using TJI studs provide more simplicity/speed when framing than double stud walls?
What is the lumber usage comparison between the two, does one use significantly less wood?
Any other thoughts, concerns, or difficulties for either system would be highly appreciated.
