Hello there – I am working on retrofitting a brownstone in Brooklyn NY to near Passive House standards. Considering using Air Krete – I would love to hear some feedback; at first it looks like a good product save to install and enviro friendly; also they state a high R value !
any comments are appreciated.

Also working on this project with Dominik.
We have an existing 12" masonry wall in a landmarked building. Interior timber studs creating a 4" cavity, which is somewhat flexible.
Is there a moisture barrier and/or a vapour retarder needed between the existing masonry wall and the airkrete?
- Water infiltration: we are concerned about water infiltration from the exterior through the existing brick wall into the masonry based Airkrete.
- Vapour Infiltration: from exterior, under Summer conditions.
Any help would be highly appreciated.
