WRB suggestion that can stand exposure?

Beardoh | Posted in Pretty Good House on

Reading about some of the peel and stick WRBs, many cannot be exposed for lengthy periods.  As I plan for the start of a build this summer, making siding decisions at the moment is not in the cards (bigger fish to fry).  

Anticipating the possibility of the WRB being exposed for some months (worst case through the winter) for either weather, scheduling or supply delays, can someone recommend a WRB…or even cheap protection for the WRB (say Tyvek temporarily on top of a peel and stick product)?

Background:

– Climate Zone 6A (New Hampshire central)
– Wall is double stud assembly
– Planning on CDX Plywood for the sheathing
– 24″ overhangs

It has even occurred to me that maybe installing Tyvek to dry in, and then replacing it with a better quality peel and stick once on site. This may sound silly, but I am just throwing ideas into the ether.

Thanks in advance.

    Are you committed to using a self adhering WRB? You could look at WRBs designed for open joint claddings like Solitex Quattro, there are others.. Should be able to handle a lot of exposure. I would lean towards drying in with the product you want to use, then covering with tarps and furring strips to minimize fasteners. If you observe how the sun hits your building it may be possible you only really need to worry about the south and west walls.

      Thanks for your thoughts. I am NOT committed to using a self-adhering WRB...open to a good solution to the challenge. I see Quattro on 475.

      Good point about minimize fasteners and actually seeing what exposure is like.

        Beardoh,

        If your primary air-barrier is anything but the house-wrap, I'm not convinced adhered WRBs add much. Tyvek Commercial can be exposed for nine months. It's much harder to tear than most house-wraps, and pretty easy to work with.

          +1 on this combo. I've used it before, quick to do and doesn't add much material or labor cost. Finding Tyvek commercial will be a bit of a challenge, might be simpler to call your local Dupont rep to see who sells it locally.

          What would you recommend as a tape on the plywood?

            I like the prices and stick of zip, and that you can snag it at Lowe’s.

    PolyWall AlumaFlash, 24 month UV exposure rating.

    i used prosoco mvp fluid applied wrb on my house i am currently building and it held up well exposed this past winter (it was applied late summer). It is rated for 12 month exposure time.
