Open-Cell Spray Foam Basics: Learn More About Your Spray Foam Insulation Options

Open-Cell Spray FoamSpray foam is one of the most common types of insulation installed in households, commercial and even industrial establishments. When choosing to use spray foam insulation, you have two options — closed-cell and open-cell spray foam.

Closed-cell spray foam insulation is more common compared to open-cell mainly because it became popular first. In the beginning, there was only one company that manufactured open-cell spray foam. But since it offers many benefits and as the demand for it gets higher, other companies started offering open-cell spray foam insulation as well. One of the many leaders for open-cell spray foam is allfloridainsulation.com who performs many types of insulation in the industry.

Differences of Open-Cell and Closed-Cell Spray Foam Insulation

Open-cell spray foam insulation has a lighter composition compared to the dense composition of closed-cell spray foam. Since open-cell spray foam is lightweight and pliable, it is a better choice should you need to make some changes in your house such as when installing new wiring or changing the entire setup of that specific area where you had the insulation installed.

Furthermore, open-cell spray foam has a higher expansion rate while closed-cell’s expansion rate is very minimal. When open-cell foam is sprayed, it can expand up to 100 times over. This means that it is a better choice for smaller areas, crawl spaces and other narrow places that could have been difficult to insulate manually.

When it comes to insulating power, closed-cell spray foam offers a higher R-value compared to open-cell spray foam. R stands for the value of how much the foam can resist heat flow. The lower the R-value, you can expect less insulating power. For every inch, open-cell spray foam has a 3.7 R-value while closed-cell offer 6 R-value.

There are many more differences between the two types of spray foam insulation and it would be better if you consult with your contractor to know which one’s the best for your property. Of course, each one has its own pros and cons. What matters is how the pros would outweigh the cons according to your requirements.

Although there are some differences between open-cell and closed cell spray foam insulation, both are exceptional insulating materials that will greatly improve the energy efficiency of a home or commercial building, and are well worth the investment. And this investment will generally be recovered within 3 to 5 years.
