Starting our new life

There would be no voids for air or moisture with the house wrap attached the the exterior walls The foam will stop all air movement, so the house wrap is more of a moisture barrier to protect the OSB from what might get behind the siding of the house.

This still was not making sense so I went to the DuPont website and this is what it said for homewrap and drainwrap:

DuPont Tyvek HomeWrap is the original house wrap, incorporating unique material science that helps keep air and water out, while letting water vapor escape

The unique material structure of Tyvek DrainWrap helps hold out bulk water, while allowing water vapor to pass through it, promoting drying in the wall system, which can help prevent mold and water damage

So they seem to be a weather barrier but not a true moisture barrier. Interesting. In any event, it sounds to me like a great combination to use spray foam plus wrap now that I understand it.

Very interesting thread and thanks for sharing.

Have you already mentioned how big the house will be when complete?

Looks like quality work!

Wow, I haven't visited this thread in about a month and hard to believe so much progress! Looking beautiful.

1900 square feet not counting a usable crawl space.


My builder told me the sheetrock was going up today. I would expect by tonight the sheetrock will be done (depending on how big the crew is) with the first coat of mud done and all the concrete work will be done.

Tyvek makes multiple versions of wrap. We used their drainwrap for an EIFS exterior. It provides channels for any moisture to drain.

This is what type of Tyvek is used down here most of the time.

I used the housewrap on mine.

I also use a scrap piece of tyvek as a ground protector for my backpacking tent. At first it was very noisy, now it is broken in good and makes no noise.

Update;

Only 3 guys doing the sheetrock so it will take a little time. My bet is, they will be done tomorrow putting up the sheetrock.

The concrete work is done and looks great. I really like these guys, they do a great job.

I'm going to do some grading/tractor work today so I'll get some pictures.

No kidding. Just finding them is a chore... vetting them harder... and showing up when promised... forget about it.
