house wrap?
Alright, footings are in, floor joists are in and the framing for my workshop will go up this weekend or next weekend (weather and time permitting). I know I'll have to work quickly once the framing is in to protect the untreated lumber from the weather.

My question today - what about wraps? The plans that I have called for basically construction paper. I was originally looking at something like Tyvek, but I wonder if its overkill, plus expensive. The guys at Lowe's said that plastic will work (I can't remember if he said 2mil or 4mil).

One bit of information that may affect responses - I will be using 7/16" OSB sheathing (Yeah, I know) and will be using hardiplank siding.

Tyvek is good. There are quite a few similiar products like Typar. Usually the framer puts these on.

Plastic will not work. Plastic is not a vapor barrier. Tyvek/Typar is a one way breathable vapor barrier. That means it lets moisture out but not in. If you put up plastic you WILL have constant humidity problems and probably mold.

The guys at lowes LOL. Not laughing at you... laughing at them.

Thanks, I'll go for the good stuff and use that roll of plastic for something else (like covering my wood when it rains). I wasn't sure since its supposed to be for a shed/workshop, but it may get insulated and lived in. :-)
