I have some wall cavities that are only about 4.5″ deep. Would you use R19 and then just drywall over or would you fir out about 3/4″ or so and drywall?

    If it is available in your area, I would use damp spray cellose to fill the 4 1/2" cavity.

    Next choice would be to drywall, then blow in cellose.

    Last choice would be fiberglass insulation.
