Spray Foam Insulation: What types are available?

The world of insulation has grown to encompass many different types and forms of insulation. These different types each have their benefits and situations where they make the best choice. Knowing the difference between the types of foam insulation will help you understand what to look for and make it easier to follow what your contractor or insulation company recommends.

There are actually more types of insulation in general, but for the purposes of this information we are specifically looking at foam insulation. Spray foam insulation especially has become the most popular choice for customers and companies alike because of its ease of use, quality properties, and excellent efficiency. Georgia Foam Solutions specializes in spray Polyurethane foam, and therefore want you to understand the differences in the types of this particular foam.

The types of foam insulation fall into two main categories: open cell and closed cell foam.

Open Cell Foam

Open cell spray Polyurethane foam is a soft and cushiony form of insulation. The cells of the foam are broken, allowing air to come inside and help the insulation process. This is what gives it the “open cell” name. You can think of this type of insulation kind of like a pillow, because although it is soft and airy, it still does insulate well. Open cell spray Polyurethane foam is great for sound insulation, as well as air insulation. This makes it an excellent choice for insulation in media rooms where sound proofing is necessary, as well as the interior wall insulation in homes and apartments.

The R-value, or the measurement of how well the insulation resists heat flow, of open cell foam is 3.81 per inch of insulation. Depending on where you live, this may mean that you use more of the open cell spray Polyurethane foam in any given area to increase the overall R-value.

Closed Cell Foam

Closed cell spray Polyurethane foam is a denser and stronger insulation material. The cells of the foam are closed, only allowing for very small pockets of air. These bubbles are also filled with a gas that increases the insulation properties of this material. Closed cell spray Polyurethane can be used for both indoor and outdoor insulation, especially because it has a strong resistance to wind, rain, and other weather. Closed cell foam is excellent for creating not only an air barrier, but a moisture barrier as well, which makes it highly effective.

The R-value of closed cell foam is much higher than open cell foam, at 7.4 per inch. This means that in order to get the best insulation, closed cell foam is more effective for insulating, especially in areas that experience rougher weather conditions.

The type of insulation that you choose, or that will be recommended to you, will be based on what your needs are and where you are planning to use the insulation. You may find that closed cell foam is more expensive than open cell foam, but is a better choice for some situations. You may also end up using a combination of different insulation in any given project.
