How Insulation and Air Sealing Together Cut Your Energy Bills by Up to 15%
Homeowners in Massachusetts often notice the same problem: their heating and cooling bills seem too high, and rooms feel drafty or uneven in temperature. The solution usually isn’t a new furnace or air conditioner—it’s improving the home’s building envelope through insulation and air sealing.
When combined, these two upgrades can reduce heating and cooling costs by up to 15%, while creating a more comfortable, healthy, and energy-efficient home. Here’s a closer look at why insulation and air sealing work so well together—and why Rogers Insulation is the trusted partner for homeowners across the region.
Why Insulation Alone Isn’t Enough
Insulation is essential—it slows down the movement of heat through your walls, roof, and floors. But even if your attic has plenty of insulation, your home can still lose energy if air leaks are present.
- Gaps around windows and doors let conditioned air escape.
- Cracks in the attic floor or basement allow drafts to enter.
- Openings around pipes, chimneys, and wiring act like hidden pathways for energy loss.
If these leaks aren’t sealed, insulation can’t perform at its full potential. That’s why experts recommend pairing insulation upgrades with professional air sealing.
How Air Sealing Complements Insulation
Air sealing works by blocking unintended airflow. It targets the small cracks, gaps, and penetrations throughout your home’s structure that contribute to heat loss in winter and heat gain in summer.
When Rogers Insulation seals these leaks before or during insulation work, your home becomes a true barrier against energy waste. The result:
- Reduced drafts that make rooms feel more even in temperature.
- Lower humidity swings, improving indoor comfort.
- Greater efficiency, since your heating and cooling system doesn’t have to work as hard.
Think of insulation as the blanket and air sealing as the zipper that keeps warm or cool air locked in place.
Real Energy Savings
According to the U.S. Department of Energy and the Mass Save® program:
- Adding insulation and air sealing together can cut heating and cooling bills by 10%–15% annually.
- Air sealing alone can save an average home up to $200 per year in wasted energy.
- Homes with both upgrades qualify for substantial rebates and no-cost services through Mass Save.
Over time, these savings can add up to thousands of dollars—while increasing the value and comfort of your home.
Health and Comfort Benefits Beyond Savings
The advantages go well beyond your utility bills.
Healthier Indoor Air Quality
By sealing leaks, you reduce the flow of dust, pollen, and outdoor pollutants into your living spaces. This is especially important for families with asthma or allergies.
Fewer Moisture Problems
Air leaks can let warm, moist air enter cold spaces like attics, leading to condensation, mold, or even ice dams. Air sealing helps prevent these issues.
Quieter Homes
Insulation and sealing together provide an effective noise barrier, keeping outside sounds at bay and creating a more peaceful indoor environment.
The Rogers Insulation Process
At Rogers Insulation, we take a whole-home approach. Our process ensures that both insulation and air sealing are addressed in a way that maximizes results.
Step 1: Energy Assessment
We begin with a no-cost Mass Save® Home Energy Assessment. This includes a thorough inspection of your home’s insulation levels, thermal leaks, and airflow patterns.
Step 2: Targeted Air Sealing
Our technicians seal gaps, cracks, and penetrations in attics, basements, rim joists, and other common leak sites. Specialized equipment ensures a safe and effective seal without blocking ventilation needs.
Step 3: Insulation Upgrades
Once leaks are sealed, we add or replace insulation in key areas like attics, walls, and basements. Popular options include:
- Blown-in cellulose insulation – eco-friendly, dense, and highly effective at stopping air movement.
- Fiberglass insulation – cost-effective and reliable in many applications.
- Spray foam insulation – excellent for hard-to-reach spaces and air sealing combined.
Step 4: Follow-Up and Rebates
We provide detailed reports, ensure you qualify for Mass Save® rebates, and help you take advantage of 0% HEAT Loan financing for larger projects.
