- Air sealing is one of the most significant energy efficiency improvements you can make to your home. Attic floor penetrations should always be sealed to keep dust and mold out, and to keep energy bills down.
- Unsealed and uninsulated recessed can lights are a common source of energy loss.
- Recessed can lights and other components that can produce heat, such as electrical boxes, are a potential safety hazard. They should be kept at least three inches away from insulation using a barrier such as wire mesh.
Scout It Out: Count the recessed can lights in your home. If they aren't sealed, either have them sealed by a professional or replace them with an ENERGY STAR® qualified recessed fixture.
