Insulation & Air Sealing
Fixing leaks and drafts is one of the best ways to prevent the loss of energy in your home and get full benefits from your insulation. Some of the most common spots for air leaks are:
- Attic Access-Ways
- Electrical Outlets and Switches
- Recessed Lights
- Window Moldings
The Department of Energy recommends different insulation levels for the various parts of your home, in addition to varying insulation by climate zones. By insulating attics and basements, which tend to be the main sources of energy loss in homes, you can significantly improve energy efficiency and lower utility bills.
The attic is typically the easiest place to add insulation to make your home more comfortable. Basements, because they tend to be humid and moist, should be insulated with material such as rigid foam.
Insulating water heaters with water heater blankets is another way of reducing passive heat loss and save energy. For sealing, caulk is sufficient to seal smaller cracks and air leaks.
For larger air leaks, expanding foam sealant or rigid foam sealant or fiberglass insulation for large areas.
Proper insulation will make your home more efficient, especially in the extreme seasons of hot and cold weather. The more efficient your home is, the lower your energy bills will be. Insulation will also seal holes, which allow pollen, pollution, and dust to enter your home, and help improve indoor air quality.
