Right – Closed-cell spray foam insulates and air-seals the rim joist above a shared wall between the garage and living space.

Image

Right - Closed-cell spray foam is installed as a skim coat to provide air tightness to an exterior wall cavity before installing batt or blown cavity insulation.

Image

To ensure a complete air barrier between the garage and the house, the wall between the garage and the house was insulated and air-sealed with four inches of high-density spray foam.
