I'm currently in the process of replacing all the siding on my 1940s home. It was originally wood dutch-lap and that was covered with felt paper and asbestos siding. I'm taking all the siding off, repairing what I can, insulating, and installing Hardie siding. I'm at the point of beginning to consider what to put under the siding, specifically as a vapor barrier.
I plan to add OSB of some sort, rather than just nailing the siding to the studs. The house needs a bit of structural help, and I think it'd make installation easier.
As a long-term DIY project, I like the idea of the HuberZIP because it seems easy and seems like it'd be harder to damage as I'm finishing the rest of the house. But, it's AWEFULLY expensive, at first glance.
How would that compare to standard Tyvek house wrap? Are there other options that I can consider?
I've also heard a little about Hardie-backer, but that sounds more like an interior sheetrock replacement. Is that intended for this purpose?
So the question is, what are my options, and what kinds of things do I need to consider when making that decision?
EDIT: In case climate matters, I'm in South/Central Texas, just NW of Houston.
