Closed Cell Spray Foam Insulation - What You Need to Know

What is Closed Cell Spray Foam Insulation (High Density)?

Closed cell foam also known as the two-pound foam is one of the most energy-efficient, structurally sound, and effective insulation options characterized by a high thermal value. High-density spray foam is used for its high R-value and greater strength. As the name suggests, it is made up of completely closed components that provide a high-density cellular composition. The density of the closely packed cells ensures a high standard of insulation as compared to other traditional insulation options. The closely pressed together cells also prevent air or moisture to penetrate inside the foam hence offering a rigid and stable structure.

Around 40% of a building’s energy is wasted on average due to infiltration of air through gaps and air leaks. This wastage can be prevented by using proper insulation. The U.S. Environmental Protection Agency (EPA) has estimated around 20% of your monthly energy bills can be saved by using insulation and sealing the gaps and air leaks.

How does Closed Cell Spray Foam insulation work?

Closed Cell Spray Foam is a low-expanding polyurethane foam that forms an Air Seal wherever it is applied. According to the Federal Emergency Management Agency (FEMA), closed cell spray foam has been classified as greatly resistant to flood water and damage due to its water-resistant nature. It is a highly durable, adhesive, and warm material that is sprayed directly to the surface where it needs to be applied. It can be sprayed on almost any surface and comes in different formulas for various kinds of applications.

Areas where Closed Cell Spray Foam insulation can be applied?

The durability and robust nature of closed-cell spray foam insulation make it perfect for both residential and commercial uses. It can be applied to a multitude of areas and surfaces like metal buildings, commercial areas like offices, basement and crawl spaces, attics, pole barns, etc. It is frequently applied for roofing applications, on floors and walls of existing houses, and can also be applied to exterior areas. It can be sprayed directly on concrete, metal, stone, or solid block surfaces.

What are the major benefits of Closed Cell Spray Foam insulation?

Closed cell spray foam has a cellular composition which makes it an ideal choice for residential as well as commercial applications. Compared to open cell insulation, it doesn’t expand a lot but still reaches the nooks and crannies of the area where it is applied. The cellular structure of closed cell spray foam enables it to resist the passage of water or moisture through it, making it a practical solution for moist and damp conditions such as flood risk areas. In addition to that, it has a high thermal value per cm as compared to other types of insulation materials providing excellent temperature regulation. The high foam density, while expanding, creates a barrier to stop air passage blocking out dust and toxins while also preventing mold growth resulting in the improved air quality of your property. Since closed cell spray foam has a comparatively rigid structure, it helps improve the overall integrity of your building far better than what the other insulation materials can offer.

Why Choose Air Seal Insulation Systems for Spray Foam insulation?

Our skilled workers and installers know exactly how to customize spray foam insulation for residential and commercial spaces. Air Seal Insulation Systems offers highly cost-effective and top-quality spray foam insulation for the best insulation of your office or home.


The process of application of closed cell spray foam insulation is very similar to that of open cell foam insulation. The spray nozzle is fed via two pipes carrying two liquid components (ISO and resin). The nozzle mixes the components that react together upon application and begins to expand to create foam in just a matter of seconds. The foam then fills the application area sealing the gaps and forming an air-tight barrier.

The spray foam is typically made up of ingredients like isocyanate and polyol which mix to form polyurethane. Polyurethane foam, in and of itself, is not toxic however off-gassing in the foam products may pose health hazards for the customers. However, once the ‘curing’ process is complete, which typically takes around 24 hours, there is no need to worry about off-gassing as the gas is made inert. During the curing period, it is advisable to keep out of the installation area to avoid any health risks.

Due to its effective expansion, closed cell spray foam insulation fills in the nooks and crannies providing an excellent air barrier. This results in an excellent energy-efficient environment. Research has shown that closed-cell spray foam insulation can save up to 50% of your energy on average.

As absolutely amazing as it is at insulating, closed cell spray foam isn’t that effective when it comes to blocking sound. While open cell spray foam is comparatively better at sound proofing than closed cell spray foam, neither of them are very good sound blockers. The foam sticks to the surfaces and hardens connecting the walls together which makes it easier for the sound to transmit.

Mold needs three essential elements to grow: Moisture, heat and a food source. The key factor inhibiting the growth of mold is the tight bond the closed cell foam forms to seal a place making it impervious to moisture. The foam doesn’t rot or catch rust neither is it a food source for the mold. Hence closed cell spray foam isn’t an environment where mold is likely to grow.
