ALWAYS flash your window openings BEFORE installing windows! #construction #diy

[AlanDubiel]

Or you could use stretch tape for windows like zip or Typar butyl thus eliminating any cuts.much better methodology

[knightrider]

Try an outward diagonal cut so that the tape runs up the window sill as well.

[chadbreton]

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

[rigobertoespinoza]

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.

Even I as a non builder went WTF?? How is it waterproof at the corner?

[jonathan]

We flash tape before window installation and after window installation.

[jasonritzman]

Just going to let you guys know
When you wrap your tyvek into the window opening like this guy did you create a opening for air to get inside the house I don’t care what insulation you use foam wool glass etc wind goes up behind the tyvek past the window and leaks around the window trim

[leericaltheonly]

I thought flush cutting the tyvek and not bringing into the building was the way to go now. Even some window manufacturers are recommending this now.

[PeterCsere]

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

[alainlevesque]

The bottom corner is the most critical spot. A bow tie here is the bare minimum. Resisto corners or flex wrap are best practise. Advice like this will cost working people thousands of dollars to repair down the line, and should be taken down.

[ifandwhen-klcr]

Why not just side the building properly?

[manuelbetancourt]

Does the window needs to go behind the paper varies and bi in contact with the wood

[salmander]

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?

[shubinternet]

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.

[uraniki]

So don't work with your company, got it

[VictorAndrade-vd]

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😂
