What are the Benefits of Effective Insulation and Air Sealing?

Air that leaks through your home’s outer walls, doors, basements and windows wastes a lot of energy, increases your energy costs and can lead to an unhealthy indoor environment. Adding insulation and air sealing is one of the most effective ways to increase comfort and save energy in your home.

Benefits of effective air sealing and insulation include:

Reduced Health Risks — If done properly, air sealing and insulation reduce the risk of moisture-related mold and rot.
Improved Air Quality — Air sealing and insulation improve indoor air quality by preventing dust and pollutants from entering your home.
Boosted Comfort — Air sealing and insulation eliminate drafts and reduce outside noise, keeping you comfortable all year-round.
Increased Savings — Properly installed air sealing and insulation lower your monthly energy costs.

How Insulation and Air Sealing Works

Insulation

Any surface in your home that separates the interior from the exterior should be insulated. If applying insulation on your own, identify where existing insulation in your home may be needed. For example, in an attic, if insulation is just level with the floor joists, or if you can see the floor joists, you should add and evenly distribute more insulation. Talk to your local hardware store about the best products to use for your specific needs.

For even greater savings, we recommend hiring a trained Program Ally contractor. Program Ally contractors conduct a holistic assessment of your home and identify the best methods to add insulation.

Air Sealing

There are small, simple steps you can take to improve the air sealing of your home and save on heating and cooling costs. If addressing this on your own, identify where trouble spots in your home may be for air leaks (such as attics, basements, around doors and window frames, outlets and switches, etc.). Add weatherstripping to where the air leaks are occurring, using air sealing products like basic spray foams and silicone or acrylic latex caulk.
