So last year we had all of our interior doors and door frames replaced in our approx 40 year old house. I don't know why I didn't notice it sooner, but yesterday when the AC was running full blast, I noticed air escaping through the door knob holes in the interior doors. Apparently during installation there was no piece of wood placed in front of the doorknob holes, so air is escaping directly into the walls. It's not a huge deal but I would like to plug or insulate these holes somehow without affecting the operation/appearance of the doors or door frames.
Is this something spray foam would take care of, or is there something else better? Concern with spray foam in such a small space is that it would expand too much.
