Rainscreens and trim
This is not exactly a green building question, but more of a “secondary effects of green building” question. I am using 1/2″ plywood (.46875″ really) for furring strips and Hardi Artisan V-groove siding(5/8″ and not a lap siding). Original plan was to run it straight into the aluminum nailing fin on the windows (the fin attaches at the front of the window) and not use any trim. With the rainscreen, we now are at exactly the depth of the fin (see pic). We had thought about mounting the window on the same furring strips, but that interferes with details at the top and bottom of the window if we intend to use the Cor-A-Vent SV-3 as they depict in their literature http://www.cor-a-vent.com/uploaded_files/files/Tech%20Drawings%20PDF/cor-svc.PDF?1426524313783 I would rather install the window with fin on sheathing and not bumped out, but if that is my only choice, I suppose we could add flashing above the window ( like in this pic https://hammerandhand.com/best-practices/manual/4-rain-screens/4-2-top-window/ ) If anyone has any other neat solutions to keep our trimless look, I would love to hear them.
