Window flashing in furred out rainscreen wall
I am trying to figure out what the best practice is for window replacement in a rain screen wall. I am replacing windows and siding in a remodel. The siding will be James Hardie over a rainscreen created by using 1/2 inch furring strips. My question is should the windows be installed with nail flanges nailed to the sheathing, or should I furr the windows out 1/2 inch to match the furring strips for the rain screen? it would seem that attaching the windows to the existing sheathing is easier and does not cause issues with existing interior trim, but does this create problems on the exterior if the siding sticks out past the windows? I really wanted to run the siding into the window rather than picture frame heavy trim around them. Furring out the windows makes tying into the WRB more difficult but Peel and Stick flashing should make it workable.
My research seems to indicate nailing directly to the sheathing is the way to go, but why would furring them out not be just as good? I haven’t done windows in a long time. Are the new units made with deeper jambs to accomodate rainscreens?
I’m sure some of you that do a lot of siding and windows have very good opinions on this. Thanks in advance.
