That is not how it's done. You are creating a fail point in the corner where you put seams instead of bending it up the Jack do you make an unbroken barrier in the corner
How is a fail. The adhesive is more relaxed and stable. I've seen people bend and wrinkle it around the corners just to keep it as one piece but that's where you have a stressed corners.
Depending on the window retro fit vs new construction window. (New construction window.) I cut 2 small patches to slap inside the bottom corner. Then i lay down a 6 inch strip with a 3 to 4 inch rise on the bottom window frame cut at a 45 degree angle overlapping the 2 bottom corner pieces. Caulk around the wooden window surface leaving the bottom caulk free in case of water entering it has a way to drain. Screw/ nail window flang. Then lay flashing tape on sides covering the screws and nails. Last lay a strip on top overlapping both sides of the flashing tape. But hey im just a dumb trucker what do i know.
Ah, using the "old method" I-cut or X-cut and wrapping the housewrap into the sides, aka extending your drainage plane to the inside of the building. REAL SMART ;-P
So, what I don't understand is why don't you seal the corners with smaller pieces, and then lay the longer piece over that? It seems like it would be faster and more efficient.
Zip system stretch tape is by far the best i've used for flashing the lower window sill. Not cuts, one piece and complete coverage (I sound like a salesman) but I recommend it.
Does anyone else think it’s incorrect to put an impermeable tape intended for waterproofing over the top of housewrap instead of directly to the wood? Aren’t we trying to create a seal and a water barrier in the wood/wood interface and NOT the tape to housewrap interface? Why not apply the tape directly to the wood surfaces and put the housewrap overtop?
No it's not incorrect. Because you want the tape on the wrap to protect from water that could get behind the siding and run down into the window opening. What we do is seal tape before the window installation and after window installation. 20+ year's General Contractor.
For the sides and top you want to cut the wrap back 1" so the flashing tape can adhere to the sheathing or else any water that gets behind the house wrap from above will make its way in
Correct. Air can get behind the house wrap and there is no seal preventing it from getting into the house. I am cutting it two inches wide of the RO and taping with contact to the flange, wall sheeting, then the house wrap. No tape on the bottom flange. You could also leave a little folded on the jam and either tape the edge in the RO or rely on you low expanding foam to seal it.
you look like someone that would go to a real job site with real workers and say 'hey can i borrow your tool and pose and act like im working for my youtube video?' lmao!!!!!! 100%

Even I as a non builder went WTF?? How is it waterproof at the corner?
Or you could use stretch tape for windows like zip or Typar butyl thus eliminating any cuts.much better methodology
Yep!
Try an outward diagonal cut so that the tape runs up the window sill as well.
That's exactly what I was going to say.

We flash tape before window installation and after window installation.
Kinda over kill. I just tape bottom first then place window then tape sides last tape top. Perfect.
Why not just side the building properly?

Do you stretch it like I see others doing? Seems sketchy to me
Does the window needs to go behind the paper varies and bi in contact with the wood

That would be correct if you were using zip system because the zip board doesn’t require house rap but the seams and windows need zip tape

Fail
Flash all the way inside
lol you did a good job, funny how a few comments try to correct you , just wonder if they know what they are talking about😂
Zip is better. No cutting etc
@jonahb8083 I wanted that stuff but Lowes didn't have it. I just caulked the seam. Be just fine I'm sure.

good job
