Passed framing inspection on Friday 02/28. Insulation started that afternoon and was completed by Monday March 1st. We used all cellulose insulation between the bays for a number of reasons:
1. It is a very cost effective
2. Cellulose is blown into the bays wet so that it fills all spaces and acts as an air barrier
3. Cellulose has a high recycled content, made of recycled newspaper.
With the 1" of rigid insulation on the exterior the walls have an r-value of 23 as opposed to the typical 2x6 wall which has an actual r value of more like 17 (when you account for studs + insulation in bays)
