   Yo Bill

   Easy answer would be-what do the directions say so you don't void the warranty?

   but

   Is there an all inclusive formed into the window-nailing flange?

   Thanks for writing, there is no mention of a drip cap in installation information from the manufacturer and yes there is an all inclusive.

   Bill,

   do they show details on how they want you to use the flexible flashing and I'm sorry-may have missed it-are you using house wrap or felt paper or other?

   I am using housewrap with the flexible flashing installed per manufacturer's directions.  Basically covering the nailing flanges on the sides and top with the housewrap covering.

   The document is about 500 mb in size so instead of attaching it here is what it says about final installation.

   1. R elease the building wrap

   from above the header

   (previously taped up)

   and overlap the header

   flashing. Seal the ends with

   self-adhesive flashing or

   building wrap tape.

   2. A djust window for best

   operation.

   3. Seal the top corners of the

   window with a 1/4" bead

   of sealant. Tool into a fillet

   shape.

   4. Create a continuous air seal on the interior by integrating the rough

   opening and the window frame with low expansion polyurethane

   foam or backer rod and sealant. If installing into wood framing with

   a drain mat, apply sealant to the foam wedge on the back of the

   drain mat, integrating the back of the drain mat with the window

   frame.

   5. Ensure weep holes/channels are clear of debris for proper water

   drainage. Do not seal weep holes/channels.

   Install exterior wall surface within 30 days of window installation.

   • Maintain gap of 1/4"- 3/8" between window frame and final exterior

   wall surface. No expansion/contraction joint is needed for integral

   J-channel windows installed into a structure with aluminum or vinyl

   siding.

   • Protect recently installed units from damage from plaster, paint, etc.

   by covering the unit with plastic.

   Yes, head flashing over flange then building wrap released and layed over head flashing-tape the two slits on the corners.

   I'll see if I can find a detail-FHB mag had a recent detail in print or in FHB.com.

   Really, the head flashing will do nothing extra but it shouldn't harm anything either.  Remember, you've made a good seal on the sides, and want any water that made it behind the building wrap up above the window to be able to drain out.
