The codes mandate the minimum airtightness of a home (5 ACH50 for warmer climates and 3 ACH50 for colder climates) How did that happen? Hint: geography plays a big part. How to get to this level of airtightness when it had never been attempted before? Cherchez la trou!

Question: Can we do better? Yes! How?

1. Air control layer goes on the outside (easiest for continuity and as we have learned, continuity is key).

2. Get rid of the big holes (see rule 1 above)

3. Use a fully-adhered membrane or a sheathing with an intregrated air control layer

Wait, you say. Those 3 things sound the same or at least are related. Yes. We are glad you can see that!
