It both help seal and does the insulation. Ken packed in extra tight the cellulous into the corners and areas we suspected leaks. Packing the cellulous tight lowers the R-Value a little but resists leaks . Here are some phots of the house with the insulation done. Remember the cavity between the back of the sheathing and the drywall is 10″ . The house really holds it temperature.
