Why Closed-Cell Spray Foam is a Smart Choice for Insulating Homes
Choosing the right insulation can significantly impact energy efficiency, comfort, and long-term savings. Closed-cell spray foam insulation stands out as a highly effective solution, particularly for homes in Redwood Falls. This insulation type offers superior thermal resistance, moisture control, and structural reinforcement, making it an excellent investment for homeowners.
What is Closed-Cell Spray Foam Insulation?
Closed-cell spray foam is a high-density insulation material applied as a liquid, expanding into rigid foam. Unlike open-cell spray foam, which remains softer and less dense, closed-cell foam has tightly packed cells that create a solid barrier. This structure provides outstanding thermal performance, reduces air infiltration, and adds strength to walls and roofs.
Key Benefits of Closed-Cell Spray Foam Insulation
1. Exceptional Energy Efficiency
One of the primary reasons homeowners choose closed-cell spray foam is its high R-value, which measures thermal resistance. With an R-value of approximately 6 to 7 per inch, it significantly outperforms traditional insulation materials such as fiberglass or cellulose. This means homes stay warmer in the winter and cooler in the summer with less reliance on heating and cooling systems.
2. Superior Air Sealing
Air leaks are a major source of energy loss in homes. Closed-cell spray foam acts as an air barrier, sealing gaps and cracks that would otherwise allow drafts. This reduces energy waste and enhances indoor comfort by maintaining stable temperatures throughout the home.
3. Moisture and Mold Resistance
Redwood Falls experiences varying weather conditions, including humidity and precipitation. Unlike fiberglass or cellulose, closed-cell spray foam does not absorb water. Instead, it repels moisture, preventing mold growth and reducing the risk of structural damage due to dampness.
4. Added Structural Strength
Closed-cell spray foam hardens into a solid material, reinforcing walls, ceilings, and roofs. This added strength can enhance a home’s ability to withstand high winds and severe weather conditions, making it a valuable feature for properties in regions prone to storms.
5. Long Lifespan and Durability
Once installed, closed-cell spray foam does not sag, settle, or degrade over time. Its durability ensures that homeowners do not need frequent replacements or maintenance, making it a cost-effective solution in the long run.
Maximizing Indoor Comfort and Air Quality
Beyond energy savings and durability, closed-cell spray foam contributes to a healthier indoor environment. By reducing air infiltration, it helps prevent allergens, dust, and pollutants from entering the home. Additionally, its moisture resistance reduces the likelihood of mold-related respiratory issues.
6. Noise Reduction Benefits
While open-cell spray foam is typically better at soundproofing, closed-cell foam still provides some level of noise reduction by reducing airborne sound transmission through walls and ceilings.
7. Lower Carbon Footprint
Reducing energy consumption not only lowers utility bills but also decreases a home’s environmental impact. With better insulation, homeowners can rely less on fossil fuel-based heating and cooling systems, contributing to sustainability efforts.
Best Areas to Apply Closed-Cell Spray Foam in a Home
- Attics – Prevents heat loss and moisture buildup.
- Walls – Enhances energy efficiency and structural integrity.
- Crawl Spaces – Protects against moisture and improves air quality.
- Basements – Keeps interiors dry and reduces heating costs.
- Garages – Maintains stable temperatures and improves storage conditions.
Professional Installation for Optimal Performance

Frequently Asked Questions
1. How much does closed-cell spray foam insulation cost?
The cost varies depending on the size of the area being insulated and the thickness of the application. On average, homeowners can expect to pay between $1.00 to $1.50 per board foot.
2. Is closed-cell spray foam insulation safe?
Yes. Once fully cured, it is non-toxic and does not release harmful gases. Professional installation ensures safe application and proper ventilation during curing.
3. Can I install closed-cell spray foam myself?
DIY installation is not recommended. Professional application ensures even coverage, proper expansion, and compliance with building codes.
4. How long does closed-cell spray foam last?
It has an indefinite lifespan, often lasting the entire lifetime of a home without needing replacement.
5. Does closed-cell spray foam reduce sound?
While it offers some sound-dampening properties, open-cell foam is better for soundproofing.
6. How does closed-cell spray foam compare to fiberglass insulation?
Closed-cell spray foam provides superior insulation, moisture resistance, and structural reinforcement compared to fiberglass, which can sag and absorb moisture over time.
7. Is closed-cell spray foam waterproof?
It is highly moisture-resistant but not completely waterproof. It helps prevent water absorption, reducing the risk of mold growth.
8. Will closed-cell spray foam make my home airtight?
Yes, it acts as an effective air barrier, reducing drafts and improving energy efficiency.
9. How long does it take to install closed-cell spray foam?
Most projects can be completed in one to two days, depending on the area being insulated.
10. Can it be used in older homes?
Yes. It is an excellent choice for retrofitting older homes to improve insulation and energy efficiency.
