Hello All,

I’m about to install several windows in my carport and have a few questions about how to best proceed with the prep. The attached photo shows the front wall, where I’ve framed above and existing brick wall for window openings. At this point the framing is sheathed, but no WRB has been installed. FYI, the eaves have a 2′ overhang.

Each of the 2 pairs of front windows are only separated by a 3″ wide double stud, and the head and sill of the window framing are only about 3″ high as well.

My questions relate to what to do to the framing prior to installing the windows.

I am planning on running a continuous piece of flashing tape along the sill adhering it to both the wood and concrete sills (like an “L”). Then in ship-lap fashion I will apply a WRB above. I will then run another continuous piece of flashing tape at the top. Per the window manufacturer, I’m using dupont flex-wrap for the sills, and straight-flash to tape around the window flanges. Given the narrowness of this framing around the windows the flashing tape will cover all of the exposed wood.

1. Is there a need to put a WRB like tyvek up first on the narrow 3″ verticals separating the window pairs? Seems to me it won’t do much. If there is some value to having an air and/or vapor barrier in these areas before the windows go in, I could cover them with more of my flashing tape, but this seems like it might be overkill. Any thoughts?

2. Some water drips down and back on the 3 beams toward the house. How would you handle the intersection of the beam and the wall. If water travels back, how do I get it to shed on to the exterior of the wall, rather than travel back into the wall along the surface of the beam? I know I can caulk the joint, and I thought of cutting a drip edge somewhere along he bottom of the beam, but I’d like to back this up with a clever flashing solution. Ideas?

Many, many thanks in advance.

Andrew…
