Where to Insulate in a Home
For energy efficiency, your home should be properly insulated from the roof down to its foundation. This includes the following areas:
- Attic spaces
- Attic access doors to unfinished attics
- Knee walls in finished attics
- Ducts in unconditioned spaces
- Cathedral ceilings
- Exterior walls
- Floors above unheated garages
- Foundations
