For good energy efficiency, your home should be properly insulated from the roof down to the foundation. This includes the following areas:
- Attic space
- Ducts in conditioned spaces
- Cathedral ceiling
- Exterior walls
- Floors above unheated garages
- Rim Joists
- Foundations (Basements, Crawl spaces, Slab-on-grade floors)
Areas that are commonly neglected:
- Walls separating living area from the attached garage
- Walls and ceiling of basement garages
- Top and Bottom Plates
- Narrow cracks around window and door framing
- Electrical Boxes
