Drywallers recently finished and due to last minute insulation work around the windows, they left a gap of little less than 1" around windows. Although it's packed with foam and fiberglass, I am concerned with this gap. I was hoping it was smaller so I can run a bead of acoustical sealant. So what are my options other than having them re-do this? Builder thinks it's ok since it will be covered by window casing.
My thoughts were perhaps use backer rod and seal with acoustical selant or perhaps use some vinyl tape?
