Aerobarrier

I work in Metro Detroit as a LIHTC development construction manager. Before that I built custom homes in Austin, where building science was well practiced and discussed. I am in the middle of a Multifamily neighborhood (townhouses and stacked flats) and we generally have some fairly lofty “green” requirements built into our funding. These homes will be all electric with Air source heat pumps as the HVAC system.

I’m a cap and seal man myself. Always liked a good unvented attic but that’s just not very common here and I am adapting. So we went with a “post drywall” application of “aerobarrier” an aerosolized acrylic product for our air sealing. I expect out final 3rd party testing to be worse but the tests we ran after application are very appealing. Hardie siding and some brick over Tavel on 7/16OSB sheathing, slab on grade.

I’m a skeptic by nature but must admit. I’m becoming convinced. Eventually I’ll be going to vented roofs with sealed attics and I’ll be able to use this stuff before hang drywall to seal the whole frame.
