Tyvek Confusion


So my little project of converting a pole barn to garage continues. Studs are up, rough door opening is done.

Tomorrow i put up the 7/16 OSB. To be followed by Tyvek and Hardie panal

I have read the Tyvek literature and watched many videos. Nobody has addressed the following:

The OSB will terminate on a 4x6 support (existing) at all corners. i am going to have the OSB end about 1/4 inch from the edge of the 4x6. How do i end the Tyvex at the supports? Do i just cut flush with the OSB edge or should I somehow tuck the edge of the Tyvek behind the edge of the OSB using a putty knife or similar tool?

I suppose I could end the Tyvek flush with the edge of the OSB and than when the Hardie is up run a bead of caulk to give it a finished look.

I also thought about some type of edge moulding but cannot find PT moulding.

Just a bit perplexed as to what to do at the edge of the building. The videos I watch show the Tyvek being wrapped around the edges and continued on the next wall but not an option here.

Similarly, at the sill plate just let the Tyvek hang an inch or so below sill?

Thanks

Tyvek Confusion


I'm confused, does this building not have outside corners?
A picture would sure help.
The bottom plates need to be even with the outside of the slab. That sheathing should have been installed so it was about 1" below the slab to keep out water and wind.

Joe:

The sill plate is even with edge of slab. OSB not up yet. Regarding the corner. There are existing 4x6 supports (vertical) at the corners. I have installed PT sill plate with anchors. Than I placed studs 16 in. OC. So the OSB will be attached to studs. At the corner the OSB will lie flat against the corner supports which were pre existing.If you could PM me your email I can send a pic via phone.

I'm also confused. So will the OSB butt into the side of the 4x6 and be in the same plane, or will the OSB cover the 4x6? Either way, the tyvek needs to be continuous and taped, so why not just wrap the Tyvek around the corner? This sounds like it is being made more difficult than it needs to be.

The pre existing supports (vertical) are on plane with the new studs. Therefore the OSB,Tyvek and Hardie Panel will be sitting against the supports. Not butting up to edge but rather laying on top of support.
Here is a view from inside. The support on right of picture is on plane with the studs so as you can see the tyvek etc will be flat against the support. Question is what do I do with the edge of Tyvek, OSB and Hardie? Caulk, some type of moulding or batten. In other words I will have an exposed edge comprised of a layer of Hardie,Tyvek and OSB. How do I clean it up??

Tyvek Confusion


your building wrap will go around the corner and lap on the side. that's how it's typically done around here.

you could end it at the corner, but then you'd need to lap a piece of building wrap over the seam.

Butt the osb at the corners, wrap the Tyvek around the corner,
install corner boards and butt the hardi to the corner boards.
Caulk and paint.
I've also seen guys run a rabbit on the corner boards so the hardi
slips in behind. Works on panels. No so much on claps.

Tyvek Confusion


I redid my house last year.

We wrapped the hole house (basically big square) with a continuous piece of house wrap on the bottom then overlapped with a piece on the top. Then cut out the windows and doors.

Way easier than trying to tape seams.

Then we put on corner pieces.
