Why not just Advantech Zip sheathing and do the WRB in one pass? The amount of labor to do this seems like a waste.
There are several different ways of achieving an air tight building assembly. WE like using the Pro Clima Adhero 3000 peel and stick product because it works with all of our Pro Clima materials without compromise. Behind our blue Adhero is 1/2" structural plywood which is stronger and more air tight than the Advantech ZIP sheathing. Thank you for your interest.
@@JasonScheurerJS Interesting. Airtight house is the way to go and I am always interested in how other people do it. Is this structural plywood thing a CA requirement preventing from using Advantech? I use Zip-R on our jobs. WRB, sheathing, and exterior insulation in one pass. I have seen people make 3 go-arounds on a house to get this. Once could argue that having independent materials allows for a better solution (I agree that is possible) but is it 10% better? If it isn't 50% better than labor is not worth it unless you are in an extreme climate.
@@crabkilla The plywood needs to be structural for this home because it is small and detached. Almost all walls had structural hold downs. OSB can be that source, however some OSB's are not air tight. Plus this home is going after Passive House Certification and there are strict guide lines. Yes, I do agree that the ZIP system is faster, and less on labor, but sometimes does not meet the stringent Passive House Standards and techniques. If the ZIP system came in a Plywood choice, we would probably be using it. The main thing is the Pro Clima line of air/water barriers is the best in the World, so another reason why we do it this way.
@@JasonScheurerJS Ohh makes sense. I get that Zip isn't good enough for passive house standards. 💯. However, not sure why anyone in California climate (unless you are in Central Valley or Tahoe) would spend the money for a passive house. I live in CA and wouldn't spend the money for an airtight house, given how mild the weather is here. AZ or ME house - for sure!
