What’s wrong with this picture? It’s been a while since posting but had to share.
There are some really good things going on withy this picture, the ZIP is installed well and provides a great water control layer and the rough openings are liquid flashes!
Now for the not so good, I’m not sure why they mixed ZIP with OSB, but the air control layer is discontinuous since they didn’t seal the OSB to the ZIP.
But the biggest issue is the sealed the top of woven WRB to the rough opening. This is any issue in this scenario because the WRB can get water behind it and there is no way for it to drain out. This will most likely result in rotted out sheathing at the top of every rough opening. Luckily, the other sides of the building, where there are lots of windows, are all ZIP.
