We didn't stop with the walls, we took it all the way to the top! The attic was another important area for air sealing. We sealed all the top plates and all penetrations that came through the attic. You can see that we used spray foam again to create a superior air seal. When you look at the picture you can see a foam shoot that is stapled to the bottom side of the roof. This is called a proper vent and this allows air to travel from your exterior soffit to the attic. Believe it or not we want the attic to stay cold in the winter. This helps with moisture control and ice daming by moving the air in that area. We want that attic to stay cold! We utilized the foam to hold the proper vent in place and create another air seal at the top plate of the exterior wall.
