nc IA | Yes, I can confirm that Morton has rolls that are the width needed for a 7.5' OC column spacing, they are cut to length, then the top is sandwitched between a 2x4 and a piece of steel (or a bit shorter 2x4) then hosisted up in between the columns and nailed on. It does "fluff" out some so there ends up being some friction between the outside and inside nailers to help hold in place eventually.
I really like the idea though of that final step of spray on foam inbetween the interior nailers - would really add to a R19 standard wall thickness and secure the fiberglass.
Menards can order wider rolls as well at the counter if you check.
A key area is to make a insulation "chute" or fresh air chute leading to the eaves so that wall to ceiling transition can be insulated as much as possible but not block airflow to the eaves. On narrow truss heel setups this is one of the biggest heat loss areas. | |
