What's the idea behind the choosing a bend for your sleeve? The allowable curve radius on the lines can't be achieved within a 2x4 stud wall alone?

You'll get a better air seal, I think, if you...

P.S. Is that white layer visible from the interior the WRB? Meaning the WRB is applied directly on the studs, with siding over it?

Not sure I follow, sounds like you are listing two different options.

Worth bearing in mind is that the WRB is your primary line of defense against liquid water. The siding sheds bulk water but...

Sistering the middle 2/3 will improve the stiffness of the joist. That's good for a tile installation, as tile is brittle and excessive deflection will lead to tile system failure.

2x10s @ 16" o.c. can span a lot farther than 13'. So you have very strong and stiff floor framing (Deflecto says L/735 for SYP or DF in good condition, and that would be for a 50psf load).

Also,...

BTW, you can use the Deflecto for a girder with a little post processing.

Please check this info, as (2) 2x8s spanning 12' is way less than what is required.

If you think about it, you have each single 2x8 joist carrying 11.5' x 16" of floor load. The beam is...
