Window Bump Out Flashing
We’re in the middle of a build and about to install windows. My window supplier has a different method to install than my contractor. I can’t find either detail to completion anywhere else. Here’s the details:
1/2″ plywood sheathing
Wrapshield IT for WRB
Strapping to build out the window for rainscreen
Here’s where opinons differ.
Contractor wants to wrap furring strips with say 1′ strips of the WRB.
Seal the nailing flange to WRB strip.
Flashing Tape over the flange and strip
Window Supplier wants to caulk and seal flange directly to furring strip.
Then flash tape the flange to the WRB on the sheathing.
I can’t find any examples of either being done. This Tyvek Youtube video is the a hybrid of both and the closest example I can find. https://www.youtube.com/watch?v=vsDKqvY23lk
What is the best way to go about this? If the furring strip is sandwiched between WRB would it act the same as caulking the furring strip to the WRB?
