BlueSkin, VaproShield, and other peel-and-stick

Joe Norm| Posted inGeneral Questionson

Are the various peel and stick WRB from reputable manufacturers basically the same thing?

I was looking particularly at the two listed in the title. I have seen both used and they appear the same just a different color.

Anyone have experience with these types of products and like one over the other?

thanks

    Joe,
    Q. "Are the various peel and stick WRB from reputable manufacturers basically the same thing?"

    A. No. Some products (like Grace Ice & Water Shield) are vapor barriers. Other products (like WrapShield SA and BlueSkin VP 100) are vapor-permeable. Choose carefully: it matters.

      Thanks Martin,

      I think after reading this website and others over the last months, I am finally starting to understand.

      As much as I'd like to use one of these products "newer" WRB systems turns out they are quite expensive. Thats OK if they are totally worth it, but for someone on a tight budget do you have a proven "economy" method for air and water sealing a traditional stud framed wall?

      I am open to ZIP but like many, have always liked ply better. I think I prefer liquid sealant over tape.

      In a perfect world I would incorporate 1.5 inches of Rock Wool to the exterior.

      So my wall may look something like: Interior Paint, drywall, 2x6 frame with cellulose in bays, plywood, (insert favorite weather sealing technique here), Rock wool, Siding

      thanks!

        Joe,
        Your air barrier is likely to be the plywood sheathing layer, so you'll have to tape the plywood seams carefully with high-quality tape (perhaps Zip System tape or 3M All Weather Flashing tape).

        你的图层列表忽略水分r-resistive barrier (WRB). A WRB is required by code and recommended by building experts. Either asphalt felt or housewrap will work. More information here:"All About Water-Resistive Barriers."

          Thanks Martin,

          The WRB was where I wrote "(insert favorite.....here)"

          I was looking for a specific recommendation on a WRB when considering both budget and performance. I will read the article you linked.
