Looking for a closed cell and open cell spray foam comparison that provides facts and is easy to understand? ALL-POLY takes the guess-work out of choosing which type of spray polyurethane foam (SPF) is best for your needs. Both of these types of spray foam insulation have a specific purpose when it comes to insulating a building from the elements outside. While they share some of the same features and benefits, there are differences. For commercial or agricultural buildings, it is best to educate yourself on which one would meet your expectations first.

Closed Cell and Open Cell Spray Foam Comparison
Let’s start with some of the similarities first. Both of these SPF’s can create an air-tight barrier, offer good soundproofing and won’t settle, sad or have any significant loss of R-value. Closed cell foam insulation are exactly what the name says, meaning its cells are closed and have the ability to waterproof. This option is primarily used in roofing applications and as an insulation coating over storage tanks and outdoor pipes.
Because of its rigidity, strength and low weight, closed cell is often applied to metal roofing to provide structural support and stability. Open cell spray foam is a polyurethane foam insulation whose cells are open and porous. Although it isn’t as strong as the other, it is highly effective as an alternative to fiberglass batting or blown-in insulation. Open cell foam has an outstanding R-value depending on the thickness of the application. Some of the more common areas that open cell foam would be used are ceilings and walls of buildings.
Closed Cell and Open Cell Spray Foam Cost
Neither one of these super-insulating foams would ever be accused of being cheap, but on the same hand, they are affordable and have an amazing return on investment or ROI. The average cost for installing closed or open cell foam insulation is completely dependent upon the size and scope of the project. We’ve applied spray foam insulation to buildings for as little as $3500 and as high as $125,000. Every situation is unique, but we always make sure the price you pay is fair and honest.
Open cell foam has an R-value of 3.8 per inch layer (approx) while closed cell has an R-value of nearly 6.5 per inch. Add more layers and get a higher R-value. So, now that you know the difference between closed cell and open cell foam, let’s help you plan on replacing your existing insulation today.
