We’re going to be using a combination of blown-in and fiberglass insulation for this room. We drilled 3/4″ holes in the top-center of each cavity of the exterior walls where the blown-in insulation will be injected. This is the west wall.
This is the north wall. Only about half of this wall will get blown-in insulation. The part of the wall that is exposed in the back attic will get fiberglass insulation.
