What is the best way to insulation an old house with lath and plaster?

Ricardo Perez-Concepcion

Many houses have walls made of lath and plaster and some don't have insulation between the interior wall and the sheathing. Then the cladding is installed outside the sheath. While replacing the cladding for those houses, is it a good idea to remove all the old cladding and sheath, spray foam between the studs and then install new sheath and cladding allowing for proper space between the sheath and the clad for air flow and water drainage.
