For several years, we’ve been using the ZIP System on our exterior framed walls. ZIP is a structural sheathing that provides a moisture/vapor barrier that provides for an incredibly tight house.
The benefits? Have you ever seen house wrap on a home after a few weeks – torn, blowing in the wind, holes? That’s because it is normally weeks between the time a vapor barrier is installed and the time the siding goes on. And what happens during that time? Typical house wrap, tacked on to the home, takes a beating.
