Air sealing a dropped soffit
from Pro Remodeler
A standard feature in many kitchens is a 6 or 12-inch-tall soffit that runs at least partly along an exterior wall. Unless this soffit is properly air sealed, it creates a big air leak in the ceiling that wastes energy and draws unconditioned air into the house. It also provides a path for moist air from the surrounding conditioned space to leak into the attic, where it deposits condensation and reduces the R-value of the insulation.
