Open-Cell vs. Closed-Cell Spray Foam: How They Differ
Attic Insulation
Both open-cell and closed-cell spray foams insulate effectively, but they work in distinct ways. Understanding their differences can help you pick the right one for your needs.
The Basics
Open-cell spray foam is a lightweight, flexible material that expands significantly—up to 100 times its original volume—making it ideal for sealing small gaps and hard-to-reach spots. Its R-value (a measure of heat resistance) is lower, typically around 3.5 per inch. On the other hand, closed-cell spray foam is denser and more rigid, expanding only about 30 times its size but boasting a higher R-value, usually between 6 and 7 per inch.
Open-cell foam is often used in interior walls to insulate and dampen sound between rooms. Closed-cell foam, with its sturdier structure, is commonly applied in places like metal buildings, shipping containers, or exposed exterior surfaces.
Advantages of Each Type
Closed-Cell Foam Benefits:
• Superior insulation in tight spaces
• Boosts a building’s structural strength
• Acts as a moisture barrier
• Resists water damage
Open-Cell Foam Benefits:
• Expands widely to fill irregular spaces
• Provides excellent noise reduction
• Costs less per application
• Seals cracks effectively
Digging Deeper: What Sets Them Apart
Cell Structure
The terms "open cell" and "closed cell" refer to the foam’s cellular makeup. Open-cell foam has airy, interconnected pockets that make it soft and pliable. Closed-cell foam, by contrast, has tightly packed cells that block air and moisture, resulting in a tougher, more solid material.
Density
Density is another key difference. Open-cell foam is light, averaging about 0.5 pounds per cubic foot, which enhances its soundproofing abilities. Closed-cell foam is heavier, often around 1.75 pounds per cubic foot or more, contributing to its durability and insulation power.
Insulation Performance (R-Value)
Closed-cell foam outperforms open-cell foam in terms of R-value per inch, making it a top choice for maximum heat resistance. However, open-cell foam’s ability to expand and fill gaps can make it just as effective overall in certain applications, despite its lower R-value.
Expansion Rate
Open-cell foam grows dramatically—up to 100 times its size—allowing it to cover large areas with a single spray, often reaching a thickness of 3 inches. Closed-cell foam expands less, to about 30 times its size, and is typically applied in 1-inch layers, building up R-value with multiple passes.
Making Your Choice
When deciding between open-cell and closed-cell foam, think about:
• Your primary goal (insulation, soundproofing, or moisture control)
• Where it’s being applied (walls, roofs, or exterior surfaces)
• Your budget (closed-cell foam tends to cost more due to its higher R-value and density)
Spotlight on Closed-Cell Foam
Closed-cell spray foam stands out for its efficiency. It creates a strong air and moisture barrier, resists water damage, and can strengthen a structure significantly. With a density of around 2 pounds per cubic foot and one of the highest R-values available, it’s a go-to option for challenging environments like cold floors, metal buildings, or even wine cellars.
