Spray Foam vs. Blown-In Fiberglass Insulation: Which Is Best for Your Home?

If you’re looking to improve your home’s energy efficiency, lower utility bills, and increase comfort, choosing the right insulation is essential. At Koala Insulation of SE Arlington, we specialize in high-quality insulation solutions for homeowners in Arlington, TX, and surrounding areas. Two of the most popular options are spray foam insulation and blown-in fiberglass insulation—but which one is right for you?

In this guide, we’ll compare the benefits, costs, and performance of these insulation types to help you make an informed decision.

What Is Spray Foam Insulation?

Spray foam insulation is a high-performance option that expands upon application, creating an airtight seal in attics, walls, and crawl spaces. It comes in two types:

• Open-cell spray foam – Lightweight and flexible, ideal for soundproofing and air sealing.

• Closed-cell spray foam – Denser and moisture-resistant, offering higher insulation value.

Benefits of Spray Foam Insulation:

? Superior Energy Efficiency – Seals air leaks, reducing heating and cooling costs.

? High R-Value – Provides excellent thermal resistance compared to other insulation types.

? Moisture and Mold Resistance – Helps prevent moisture buildup and mold growth.

? Long-Lasting Performance – Does not settle or degrade over time.

Drawbacks of Spray Foam Insulation:

? Higher Upfront Cost – More expensive than fiberglass but provides long-term savings.

? Professional Installation Required – Needs specialized equipment and expertise.

What Is Blown-In Fiberglass Insulation?

Blown-in fiberglass insulation consists of fine glass fibers that are blown into attics, walls, and other spaces. It’s a cost-effective and efficient insulation option, commonly used in homes for added thermal protection.

Benefits of Blown-In Fiberglass Insulation:

? Affordable and Budget-Friendly – Lower initial cost than spray foam.

? Efficient Thermal Performance – Helps maintain indoor temperatures year-round.

? Quick and Easy Installation – Can be installed in a few hours with minimal disruption.

? Non-Combustible – Naturally fire-resistant for added safety.

Drawbacks of Blown-In Fiberglass Insulation:

? Less Effective Air Sealing – Does not fully prevent air leakage like spray foam.

? Settles Over Time – May lose effectiveness as it compresses.

? Moisture Concerns – Can retain moisture, leading to mold issues if not properly ventilated.

Spray Foam vs. Blown-In Fiberglass: Which Should You Choose?

The right insulation depends on your home’s needs and budget:

• Choose spray foam insulation if you want maximum energy efficiency, long-term savings, and superior air sealing. It’s ideal for sealing cracks, preventing drafts, and improving indoor air quality.

• Choose blown-in fiberglass insulation if you’re looking for a budget-friendly option that provides good thermal protection and quick installation. It’s great for attics and retrofitting existing homes.
