 On top of that foam insulation, we applied a wood furring strip that gives us an air gap between the cladding of the home and that insulation so that if any wind-driven rain were to get behind the cladding, the lap siding, there is an air gap where that water can drain and it's not held against the home where it's going to cause swelling, mold, any other kinds of durability issues that a lot of our homes around this area do suffer from.
