   Care to link up to this Blueskin window pan technique you are using..................never heard of it.

   Did you place a pc of beveled siding or other base on the sill (to slope to direct any water out)?

   You mention tyvek on the jamb/head.   Do you mean you wrapped the side jambs AND the head (pulling in and fastening?  If so, best look up the window install detail, the head will get pulled up and lap over the peel and stick window flashing.

   no link, and "regionalisms"

   The Blueskin comes in bare rolls on a pallet, without retail packaging or instructions. I have contacted http://www.henry.com for instructions as their website has nothing.

   I wanted to use like a Dow Weathermate preformed sill pan product but ironically(?) in leaky condo land no one uses or stocks them.

   I have been looking at builds for the past couple of years (in anticipation of our own build), and also drove by half a dozen on Saturday, and everyone here does it this way. That is, 12" wide strip of Tyvek jamb and head wrap, Blueskin peel-and-stick sill pan. All this without wall Tyvek. No one does the extra step of bevel siding. Some (including myself) do a strip of small lumber back dam detail. So this is how its done in my region.

   Additionally, the prerequisites for the sheathing inspection preclude the superior "inverted martini glass" window opening cuts in the wall Tyvek. *You have to have your sheathing full installed AND the windows & doors for the sheathing inspection. Once it passes then you can install the wall Tyvek. This sequence is bass ackwards but as far as I can determine the BI's are concerned with Code issues, not durability and since our code does not include the "inverted martini glass" technique they don't help you implement it. (Case in point when I asked about house wrap & rain screen inspection I was told they don't do that.....hello leaky condo!)

   So back to my original question, we are doing the (local) normal thing and applying Blueskin across the sheathing at the sill. Then cutting it and folding it into the sill. A 3x9 rectangle is wrapped around the base of the jamb and onto the sheathing. This leaves a tiny hole in the corner. A gusset "patch" is cut and applied by stretching over this hole area. *I suspect the size and shape of the patch we have used makes it too big of a stretch to conform to the corner, and as it relaxes it pulls away from the exterior Blueskin and curls up.

   For the ones already done would spray primer under the curled edge work? Tuck tape could be used to hold it while it bonds.

   For the remaining ones to be done can someone provide gusset patch size/shape details?

   Thanks

   John

   Can't answer your Blueskin question but why not wrap the windows with a 12" piece of Tyvek and leave the outside edge loose. When it's time to do the walls tuck and tape.

   Where the heck are you?

   That type of forming flashing is not that odd.

   or

   order and have it shipped.
