What Is Spray Foam Insulation?

Spray foam insulation is a two-component mixture that expands on contact to create an airtight seal. It’s applied as a liquid, which then rapidly expands to fill gaps, cracks, and cavities. There are two main types:

• Open-cell spray foam: Lighter and more flexible, with a lower R-value, but excellent for interior walls and sound dampening.
• Closed-cell spray foam: Denser and moisture-resistant, with a higher R-value, making it ideal for exterior walls, basements, and attics.

Both types offer unique benefits and can be applied throughout different areas of your home depending on your goals and budget.

1. Superior Insulation Performance

Spray foam has one of the highest R-values per inch of any insulation material on the market. The R-value measures how well insulation resists heat flow—higher is better. Closed-cell spray foam has an R-value around R-6.5 to R-7 per inch, providing excellent thermal resistance.

In a region like Northwest Arkansas, where weather can shift from hot and humid to cold and damp, having a strong insulation barrier is key to maintaining consistent indoor temperatures.

2. Exceptional Air Sealing

Unlike traditional fiberglass batts or blown-in cellulose, spray foam seals the building envelope by expanding into every crack and crevice. This air-tight seal reduces drafts and keeps outdoor air from infiltrating your home.

This air-sealing quality improves overall energy efficiency, minimizes allergens and pollutants, and reduces the strain on your HVAC system—especially during peak heating and cooling months in Arkansas.

3. Moisture and Mold Resistance

Northwest Arkansas homes are no strangers to humidity and rainfall. Moisture can easily infiltrate a home and lead to mold growth, especially in basements, crawlspaces, and attics.

Closed-cell spray foam acts as a moisture barrier, helping to keep water out and prevent mold and mildew from forming. It also adds structural support to walls and roofing systems due to its rigid form once cured.

4. Improved Indoor Air Quality

Spray foam helps reduce the infiltration of allergens like pollen, dust, and outdoor pollutants. By sealing the home’s envelope, it helps maintain cleaner air inside—an important benefit for families with asthma, allergies, or respiratory sensitivities.

For many homeowners in Northwest Arkansas, better indoor air quality translates into better health and overall quality of life.

5. Noise Reduction

While closed-cell foam is excellent for energy and moisture protection, open-cell spray foam also offers outstanding sound-dampening properties. It’s perfect for use in interior walls to reduce sound transfer between rooms, providing a quieter and more peaceful home environment.

Whether you live in a busy neighborhood, near a main road, or simply want more privacy, spray foam insulation can make a noticeable difference.

6. Energy Savings That Add Up

By reducing air leaks and increasing thermal resistance, spray foam helps your heating and cooling systems operate more efficiently. Homeowners typically see a 20%–30% reduction in energy bills after upgrading to spray foam insulation.

These long-term savings often offset the higher upfront cost of spray foam compared to traditional materials. Plus, with energy prices continuing to rise, the return on investment continues to grow.

---

7. Long Lifespan and Durability

Spray foam insulation doesn’t sag, settle, or degrade over time like fiberglass or cellulose can. Once it’s installed, it maintains its shape and performance for decades. That means fewer worries about re-insulating your home in the future.

When properly applied by professionals like Koala Insulation of Northwest Arkansas, spray foam provides lasting protection for the life of your home.

8. Increased Home Value

Energy-efficient homes are in high demand. Adding spray foam insulation not only boosts your comfort but can also increase the value and resale appeal of your property. It’s a great selling point for buyers looking for lower energy costs and better indoor performance.

Where to Use Spray Foam in Your Home

Spray foam can be applied throughout various parts of your home, including:

• Attics and roof decks
• Exterior and interior walls
• Basements and crawlspaces
• Rim joists and around plumbing penetrations
• Garage ceilings and walls

Each space benefits from spray foam’s ability to insulate and seal in one step.
