What’s the Difference – Open Cell and Closed Cell Foams

The importance of distinguishing between the two types of spray polyurethane foam cannot be understated. When it comes time to insulate a home or commercial building, you must opt for open-cell foam or closed-cell foam, or a specific combination thereof. Each type of foam distinctly impacts project costs, application methods, and building performance. There are two major factors distinguishing closed-cell and open-cell foams: structure and density.

Cell Structure

The structure of open-cell foam consists of tiny bubbles or cells that aren’t fully encapsulated–they are broken, torn, ripped, etc. Because they’re broken, air fills the open space inside the bubble, which results in a soft, spongy material.

Closed-cell foam differs in that every bubble or cell that makes up the foam is completely encapsulated and packed tightly together. The bubbles aren’t filled with air, but rather a gas that aids foam expansion and insulation properties. This results in an altogether harder, stronger material than open-cell foam.

The blowing agent, which aids in forming the bubbles or cells that make up SPF’s foam structure, is usually water for open-cell and high-R-value chemicals for closed-cell.

Closed-Cell vs. Open-Cell Material Density

Closed-cell foam is roughly four times as dense as open-cell for insulation applications. To ascertain foam density, one cubic foot (cu. ft.) of foam material is weighed. Open-cell tends to be roughly 0.5 lb./cu. ft. in density, whereas closed-cell ranges from 1.7 to 3.0 lb./cu. ft. in density, or even higher for certain applications. (Note: these density figures are rough averages. Every SPF product will differ based on its formulation.)

Insulation Values

R-value is a way to denote a material’s insulating properties, and the higher the number per unit thickness, the better the insulation value. Closed-cell spray foam has an R-value of about 6.0 per inch (R-6), while open-cell SPF comes in at roughly R-3.5. (Note: these R-values are rough averages. Every SPF product will differ based on its formulation.)

Spray Foam Soundproofing Systems and Airtight Systems Qualities

Spray foam expands to fill all cracks and crevices. This ensures an airtight system is in place.

The Airtight Insulation Solution

Air Tightness Systems

Reduce Air Leakage

Air leakage is a common problem that results in higher heating and cooling costs for some property owners. Spray foam insulation application helps prevent air leakage, as the solution expands up to 100 times its volume to fill cracks and holes that otherwise would contribute to this issue.

Selecting the correct type of insulation for improving air tightness within a structure is an important decision as some insulation methods are more effective than others.

Suitable for attics and new extensions.

The air tightness spray insulation are most suitable for a verity of reasons. Unlike most other forms of insulation, our insulation guarantees an air tight seal in its results.

Can be Sprayed on any surface

Sprayed on any surface, our spray foam insulation expands rapidly from its liquid state and perfectly seals any gap or crevice ensuring the perfect air tight, heat loss barrier and providing a neat finish.
