Benefits Of Spray Foam Insulation

Improve Comfort, Energy Efficiency, and Air Sealing with Spray Foam
Spray foam insulation is a high-performance system that expands after application to fill cracks, gaps, joints, and irregular spaces. Unlike traditional insulation, it adheres directly to surfaces, creating a more continuous insulation and air-sealing layer.
Camco Insulation installs both open-cell and closed-cell spray foam insulation throughout Long Island. While both improve energy efficiency and comfort, they differ in density, strength, moisture resistance, and ideal applications.
Selecting the right type depends on the installation area, project goals, cavity depth, moisture conditions, and building-code requirements.
Core Benefits of Spray Foam Insulation
Air Sealing and Energy Performance
Spray foam’s ability to expand and seal gaps helps reduce uncontrolled air movement through areas such as framing joints, penetrations, rim joists, and attic bypasses. By limiting air leakage and heat transfer, it can help HVAC systems maintain more stable indoor temperatures and potentially reduce heating and cooling demand.
Improved Comfort and Indoor Conditions
By minimizing drafts and uneven insulation, spray foam can improve temperature consistency throughout a building. This may reduce hot and cold spots, enhance comfort in upper floors and rooms above garages, and stabilize conditions near exterior walls and ceilings.
Continuous Coverage in Irregular Spaces
Because it is applied as a liquid that expands, spray foam conforms to complex shapes and hard-to-reach areas, including narrow cavities, curved surfaces, and renovation spaces with irregular framing. Its adhesion to approved substrates helps create a continuous insulation layer when properly installed.
Durability and Long-Term Stability
Once cured, spray foam remains in place and does not settle like loose-fill insulation. Its performance depends on proper installation, building conditions, and protection from moisture or damage.
Additional Performance Benefits
- May reduce some outdoor noise by sealing air gaps (open-cell performs better for sound absorption)
- Can help limit entry of dust and outdoor pollutants
- May improve HVAC efficiency when air leakage is reduced
- Suitable for residential and commercial applications, including attics, walls, basements, crawl spaces, and more
Spray foam does not replace ventilation, filtration, or moisture control systems, and overall performance depends on the entire building design.
Types Of Spray Foam Insulation
Closed Cell Spray Foam
Closed-cell spray foam insulation offers superior energy efficiency with a high R-value, providing excellent thermal resistance and reducing energy costs. Its dense structure creates an airtight and moisture-resistant barrier, preventing water damage and mold growth. It also strengthens building structures, adds durability, and is highly effective in tight spaces due to its space-saving qualities. Closed-cell insulation lasts for decades without degrading, ensuring long-term performance. Ideal for areas prone to moisture or extreme temperatures, it enhances comfort, improves air quality, and increases the structural integrity of homes and commercial buildings.
Key Advantages
High R-Value in Limited Space
Closed-cell foam delivers greater thermal resistance per inch, making it ideal for shallow cavities or areas requiring strong insulation performance in a thinner layer.
Air Sealing and Vapor Resistance
It combines insulation with strong air-sealing properties and, at sufficient thickness, can act as a vapor retarder. This makes it suitable for areas where moisture control is important.
Moisture Resistance and Durability
Closed-cell foam resists water absorption more effectively than open-cell foam and forms a rigid surface that can add durability to assemblies. It may also contribute to structural rigidity, though it is not a substitute for structural components.
Versatility in Challenging Environments
It performs well on masonry, concrete, and metal surfaces and is commonly used in areas with higher moisture exposure or limited space.
Typical Applications
- Basement and crawl-space walls
- Rim joists
- Masonry and concrete surfaces
- Metal buildings
- Shallow wall or roof assemblies
Closed-cell foam is often selected where higher insulation performance, moisture resistance, or structural rigidity is needed.damage and mold growth. It also strengthens building structures, adds durability, and is highly effective in tight spaces due to its space-saving qualities. Closed-cell insulation lasts for decades without degrading, ensuring long-term performance. Ideal for areas prone to moisture or extreme temperatures, it enhances comfort, improves air quality, and increases the structural integrity of homes and commercial buildings.
Open Cell Spray Foam
Open-cell spray foam insulation is an affordable and effective solution for improving energy efficiency. Its light, expansive structure fills cracks and gaps, creating an air barrier that reduces energy loss. With a lower R-value than closed-cell, it’s ideal for interior spaces, providing excellent soundproofing and noise reduction. Open-cell foam is also vapor-permeable, allowing moisture to escape and reducing the risk of condensation issues. It's more flexible, accommodating structural shifts without cracking. Easy to apply and cost-effective, open-cell insulation is great for walls, ceilings, and attics, offering improved comfort and energy savings.
Key Advantages
Efficient Expansion and Coverage
Open-cell foam expands significantly, making it effective for filling large cavities such as attic rafters, wall studs, and ceiling assemblies while sealing small gaps.
Air Sealing and Sound Absorption
It provides reliable air sealing when installed correctly and is particularly effective at absorbing sound, making it suitable for interior walls, bedrooms, offices, and multifamily buildings.
Cost-Effective for Large Areas
Due to its lower density, open-cell foam typically uses less material per inch, making it a practical option for insulating large or deep cavities where space is not limited.
Flexibility and Drying Potential
Its softer structure allows for minor building movement, and its vapor permeability can allow assemblies to dry under the right conditions. This makes it suitable for certain roof and wall designs when moisture management is properly addressed.
Typical Applications
- Attic rooflines and cathedral ceilings
- Exterior wall cavities
- Interior partitions and sound-control walls
- Floor and ceiling assemblies
Open-cell foam is best used where sufficient cavity depth is available and moisture exposure is controlled.

Important Considerations
Spray foam performance depends heavily on proper installation. Key factors include:
- Surface preparation and moisture levels
- Temperature and environmental conditions
- Correct application thickness and technique
- Adequate curing and ventilation
- Compliance with manufacturer guidelines and building codes
Spray foam should not be applied over wet materials, active leaks, mold, or damaged surfaces without first addressing those issues.
