I have an outbuilding that was partially finished when we moved (exterior stucco done, studs & half insulated w/electrical inside) that I want to complete and part of those plans involves installing a window on the side. From everything I have looked at online it seems normal installation is to break up the stucco, peel back the paper, and nail the fins to the wood frame if I understand correctly. However, I believe this building was built as follows: studs -> foam board -> chicken wire -> stucco so i'm not sure where to go here since I'm about 90% sure there's no paper between foam and stucco. In addition, the window I got doesn't have any fins or anything like that on it but the instructions say to screw it in through the frame. Thankfully, i'm in Las Vegas so we don't get much rain or moisture here but I still want to do this as correct as I can.My original plan (granted before I looked in to the specifics and got confused by flashing) was to frame in a hole slightly bigger than the window on the inside, cut that hole all the way through the foam and stucco, shim & screw the window in as directed, and seal the outside edge somehow (caulk?). The question is on that last bit mainly, and i'd like to get my ducks in a row before I start cutting holes.Any advice is greatly appreciated via /r/DIY https://ift.tt/2GRw9rJ
