Air barrier for existing masonry party wall?
Hi. I’m wondering if anyone has any experience with spray-applied air barriers for existing masonry party walls.
I’m in Philly designing Passivehouse infills and we need a way to continuously air seal the face of adjacent brick party walls to maintain our envelope. We usually use closed cell spray foam, but it is not accepted as a reliable air barrier. Any product or method suggestions will be greatly appreciated. Thanks.
