Importance of an air control layer: Modest House 29

Most people underestimate the importance of an air control layer. They say their home needs to breathe....As a wise man once told me, if your house is breathing call an exorcist. You want a well detailed air control layer that also controls the vapor inside your home and more importantly, your wall cavity. You should control the fresh and clean air that you bring into your home.

Siga Majrex is the gold standard for vapor barriers/air control layers. It isn't cheap, but it works! Everyone asks where to buy this stuff. Check out https://performancebuildingtapes.com/. I have no affiliation but that's the place to go or reach out to your local SIGA rep and you can also buy direct.
