Hello again to all. We just received the two bay windows we are installing and they have no nailing flanges. The units merely slip into the r.o. and screw through the seat, head, and sides into the framing. Just curious as to the best way to flash these windows. Thanks.

........................QUESTIONS
Do they have an attached brick mould or other exterior finish trim?
Are they clad? What is the brand and stock number?
Describe the frame profile---or provide a drawing/photo.
Consult with the manufacturer....on line possibly.
Just a start to gather enough info to answer the question........Iron Helix
Thanks for the rsponse. There is no attached trim. They are XACT bay units w/ 2 sidelightsts 45 degrees to the face. They are clad. Thanks again.

So if these are clad, then I assume it is aluminum clad and the interior is wood, and they have insulated glass. ?
If they are aluminum clad, please check to see if there is a formed groove in the aluminum perimeter frame that might be designed for the application of a splined nailing flange and drip cap.?!
I'm not familiar with the XACT brand of windows, so I'm at a loss as to how they are built. Is there a local dealer that would have a spec/tech sheet? Can you order nailing fins from XACT? 1-800-????/ http://www.xact.com?
What are the dimensions of this window unit? How far does the 45 deg. bay project out from the exterior wall? How are you supporting the extended load from the bay window? A few screws in the seat and head board doesn't seem to be a good install for a bay window. What do the instructions say?
Sorry for all the questions, but that is what gives me the details with which to try to answer your question without seeing the actual window and installation.

Just found XACT windows on the net...................they are not "clad"...they are vinyl.
XACT (at least the one I found) sells only vinyl replacement windows designed to be installed in the existing framed window opening. Therefore they have NO nail fin, or flashing because the existing frame has aleady been installed.
Replacement units when fitted to an existing window frame are caulked to seal to the existing frame. Replacement window are made to the 1/8" of opening measurements.
Replacement style windows can be converted to "new construction rough opening" application by retro-fitting a special metal extrusion to act as a nailing fin. This must be ordered from the factory and installed to the window with sealant and then the window may be installed in "new construction" fashion.
Does this help your problem/question?

You the Man!!!
I just looked up initiative in the dictionary...man, are you ugly.
Job well done!
Your absolutely right. They are vinyl. I was rushing and didn't clarify that the wood components are wrapped (clad) in vinyl. I was sold these windows by a distributor who knew full well they were being put into a framed rough opening not an oold window frame (boy would that be a big window! the bays are 5ftw/6ft!) Plus , and maybe it's just me, how the heck is a window frame going to hold the weight of a bay unit? Anyway, now I have these windows and need to flash them. The top is no problem as there is a soffit above which I am finishing the window to. Below, obviously the projection of the bay will help keep water out so I really need to seal the two sides. I wrapped the r.o in Vycor and used a pan on the sill in addition to the Vycor overlappin everything shingle style. I called Vycor and gave them the scenario and recommend a good bead of 1 part urethane sealant between the projecting side of the bay and the Vycor and then run the tar paper to the sides of the window. I hate only relying on caulk so any suggestions are appreciated. I won't be using these (nor that distributor) again! Thanks

Oh I forgot, it gets screws threw the seat, head, and sides every foot and uses a cable support system to help with the load. Their instruction also refer to a r.o. not an existing frame. I also went to their web site. They do list the 6000 series (which is what I ordered) as "new construction".

I'm glad to hear about the cables for support, but still am perplexed about the lack of a nailing fin for "new construction" vinyl windows.
Does it possibly have an integral J-chanel/unpunched nail fin.....or does it have chanels for attachements of nailing fins that were inadvertently "not shipped" with the window?
A nice digital photo of the window's edge would be great.....borrow, beg...or ?...and then post with your next note.
It really is time to call in the sales rep to get to the bottom of this problem. Spec sheets, cross-sections and install instructions are paramount to a solution that is correct.
