Blistering hot and humid summers give way to frigid, damp winters—putting a strain on your home’s energy efficiency and your wallet. While insulation is crucial, there’s another key factor that often gets overlooked: air sealing.

Air leaks are the hidden culprits behind high energy bills, uncomfortable drafts, and poor indoor air quality. Chances are, if you were to have your home blower door tested, you would discover more air leakage than you expected. No matter where they are, air leaks compromise your home’s energy efficiency and overall comfort.

That’s where spray foam insulation shines as an ideal solution for air sealing. Unlike traditional insulation materials, spray foam expands up to 100 times its volume to fill every gap and crevice, creating an airtight barrier that blocks air leaks. The result? A home that is insulated and air sealed with one application for improved energy efficiency, enhanced comfort, better indoor air quality, and so much more.

The Building Science of Air Leaks

Air leaks occur when outside air enters and conditioned air exits your home through unsealed cracks and gaps in the building envelope. These problem areas are often found in the attic, crawl space, around windows and doors, electrical outlets, rim joists, exterior walls, and even in each wall cavity. Locally, in the Murfreesboro and Nashville areas, the biggest air leakage challenges are in older homes and homes with poorly insulated attics.

The Benefits of Spray Foam Insulation for Air Sealing

Spray foam insulation is a game-changer when it comes to air sealing. Insulation acts as a thermal barrier, but it doesn’t prevent air leakage, while spray foam does both in one easy step to create a seamless, airtight barrier. This delivers a host of benefits for Murfreesboro and Nashville homeowners:

Energy Efficiency

Reduce your heating and cooling costs thanks to less heat loss in winter and heat gain in summer.

Comfort

Enjoy consistent temperatures, reduced drafts, and improved indoor comfort throughout your home.

Indoor Air Quality

Prevent outdoor pollutants, allergens, and moisture from infiltrating your living space.

Noise Reduction

Enjoy a more peaceful, quieter living environment by blocking outside noise.

Structural Strength

Enhance the structural integrity of your home.

Pest Control

Help keep insects, rodents, and other pests out of your home by sealing up their entry points.

Why Choose Spray Foam Insulation Over Other Air Sealing Methods

Compared to traditional air sealing methods like caulk and weatherstripping, spray foam insulation stands out for its superior effectiveness, longevity, and versatility. While these other options may provide a temporary solution, spray foam creates a permanent, seamless air barrier that won’t shrink, gap, or degrade over time. It’s offered in two forms—open cell and closed cell—that allow you to choose the best spray foam for your insulating needs.

Cost is often a concern with spray foam. Thankfully, the long-term energy savings and increased home value afforded by spray foam insulation often outweigh the initial investment. This makes it a smart choice for Murfreesboro and Nashville homeowners looking to create an insulated and air sealed home that is more energy-efficient, comfortable, and air-tight.
