Majority of homeowners in the United States of America concentrate on insulation or HVAC upgrades without thinking about the impact of other features on energy consumption as far as energy efficiency projects are concerned. These features focus on;
- Adding insulation
- Addressing air quality issues in the house
- Proper attic ventilation
- Air sealing
When completed, these improvements can enhance the energy efficiency of the home.
Benefits of Air Sealing
Enhance efficiency and comfort
Air can leak in and out of a house through cracks, seams, and gaps, in building materials. Moreover, air leaks create drafts that allow hot air in the summer and cold air in winter. Since adding new insulation does not solve air leakage issues, proper air sealing before adding insulation can be critical to improving overall comfort and saving money.
Improved quality of air
Pollutants from paint, air fresheners, cleaning products, stoves, fireplaces, building materials, and humidifiers can negatively impact indoor air quality. Energy experts can assist you in determining whether your house is under-ventilated, which allows the accumulation of indoor pollutants. They can recommend the addition of ventilation to reduce safety and health risks.
Moisture in the bathroom and basement can result in mildew and musty scents to grow in the home. Sealing air leaks in the crawl space or basement and ensuring exhaust fans are appropriately vented out of the house can assist in keeping moisture out and avoiding costly repairs.
Enhancing energy efficiency by sealing air leaks can assist you in saving more energy than attic insulation alone.
