Here is a comparison shot from the last post showing newly installed open cell spray foam insulation. We are filling the stud pockets and any cured foam that sits proud of the face of the studs will be shaved down to accommodate drywall. Door and window frames, framing gaps, open pockets and any gaps will be hand filled later by hand with a can foam.

At the top of the picture you can see the ceiling joist cavities filled with foam. This is called the box sill or band sill cavity- one of the worst culprits in air infiltration.
