House Sheathing, Part 2 – GreenBuildingAdvisor

Hello All,  I posted recently about concerns about adherence to all the Zip Tape rules, and was looking for other options.  You all were very helpful.  In discussing our concerns with our architect, he said that Zip is fairly forgiving even if the tape isn’t rolled right away or fully and that with our rainscreen, we would still be okay.

I ended up calling Huber because I also wanted some info on their Advantech wall sheathing (as it’s a similar price point for the non T&G product as plywood).  The guy was very helpful.  He said the Advantech sheathing can sit out, untaped and unwrapped, for 500-days, but we’d want to put a wrap on it before adding siding since it’s not an air barrier.  So, that sounded pretty good (especially since it’s a fully resin impregnated product).

He also said when I asked about issues with Zip tape (and specifically setting the warranty issues aside) that overdriven nails will be fine if they don’t go more than 1/2 of the depth of the sheet (so, 1/4″ for a 1/2″ sheet), and he also said the tape would probably be fine if it wasn’t rolled for a month or so, but there could be adhesion issues if moisture or dust got behind it.  The most important thing is not not have wrinkles or fish-mouth on the tape.  

SO, long-winded intro, but now I’m sort of maybe leaning towards Advantech wall sheathing, letting it sit until we are ready to do wall insulation, and then tape and wrap w/Tyvek Commercial at that point.

Does anybody who knows more than I do have any concerns about this approach (aside from cost)?  I know I’m all over the place here, sorry about that!
