When homeowners think of saving money on energy bills, they often think of upgrading their insulation. Insulation is a great way to reduce heat transfer and indeed is an important part of saving energy. Did you know that sealing air leaks is as important as insulating?
Here are just some of the benefits of air sealing:
- Improved indoor air quality by helping to keep allergens and pests out of the home.
- Reduced energy bills by keeping conditioned air (heated or cooled air) inside the home.
- Reduced wear and tear on your HVAC system.
Air sealing involves sealing penetration points around the exterior of the home (also known as the envelope or “shell” of the home). This includes sealing gaps and air leaks in exterior walls (around outlet covers, etc.), windows, doors, etc.
Air sealing a home is one of the most cost-effective ways to reduce energy bills and make your home more comfortable. ENERGY STAR estimates a homeowner can reduce heating and cooling costs up to 20% by upgrading their insulation and sealing air leaks.
