Connecting Top Plates of Interior and Exterior Walls
I am interested in running my 1.5″ 2×4 service cavity on the interior of my 2×6 wall straight around the perimeter of the house with no breaks. Also, keeping my Intello air barrier completely contiguous.
Typically, you would overlap the top plate anywhere an interior wall meets and exterior wall. Can I skip that and just screw my interior walls into my horizontally running 2×4 service cavity members? This would allow me to have my air barrier go up the wall and turn in at the ceiling with no breaks or penetrations.
I can’t find anything requiring you to connect these top plates in code.
I do not have any interior shear walls.
