    Blow in from the attic space is probably the best way. Anything else is going to involve changing interior or exterior surfaces.

    Hi Jama. This job requires at least 3 people. Rent a blower to blow insulation into the walls from the attic. You will also need to purchase the packages of the insulation. One guy in the attic blowing the insulation with a very long hose. One guy to keep filling the hopper with the insulation, and one guy controlling the hose. I hope you find this useful. Good luck Jama.
