Masonry Air barrier - Passive House BKLYN V

  • Passive House BKLYN V

Come see the masonry air barrier with intello plus membrane connection at the roof on our fifth PH project in Brooklyn. We are in the rough framing stage so not a ton of details to see other than the air barrier, but I am happy to go over the plans and strategy for the project and discuss some of our details that we have revised from our first through fifth.

Sturdy shoes required!

    Can the intello air membrane be bought in 10' high rolls? The air barrier prevents air from leaking through wall but allows vapor to pass both ways . My problem with this picture is that if you use a quality primer sealer under a quality paint you are preventing any vapor going out through wall and probably coming back therefore maybe an exterior and much less expensive house wrap would work .
    This is just one of the exterior wood framed wall detail that puzzles me and I will be building a house to PH standard in the Bronx very soon

      Patrick, The rolls are 5' wide only - for the time being. If your paint is a quality latex paint primer and finish, then it will not ever be more than a class 3 vapor retarder and likely not ever reaching that as the gyp board construction it is on leaks air and vapor with the air. The vapor variability of the membrane will fully function with a painted interior finish. Regarding other membranes, generally speaking, cheaper house wraps are not airtight and one will have a very difficult, if not impossible time trying to achieve airtightness with them. Happy to discuss the details for your Bronx PH and help in any way we can. You can reach us at Please be sure to see the construction details for masonry retrofits on the site. - Ken
