When it comes to foam insulation choices, we have the information you need to choose the best option for your property.

There are so many insulation choices out there for people to choose from these days. With materials made of everything from glass strands (fiberglass) and recycled newspapers to spray foam insulation choices, you can pick and choose insulation materials that will work best in every area of your property. A material that many people are choosing lately is spray foam. Due to spray foam’s ability to create tight seals and resist water and mold while also providing high R-values, it’s no wonder that we are often asked to answer questions about foam insulation choices. There are basically two different types of foam insulation choices out there:

Foam Insulation Choices in Garner, North Carolina

  • Closed Cell Foam Insulation- Closed cell foam insulation is a great choice for homes that experience extreme temperatures. The “closed cell” portion of closed cell foam insulation refers to the fact that when air is passed through the material to enable it to be sprayed, there are small air bubbles, causing closed cells. This makes the material more rigid, an extremely effective insulator, and able to fit into tight spaces.
  • Open Cell Foam Insulation- With open cell foam insulation, you end up with larger bubbles of air passing though the material, which gives open cell foam insulation a fluffier, more expansive material. Open cell foam insulation is great at fitting into the tiniest of nooks and crannies. It is also an effective soundproofing material.

Differences Between the Foam Insulation Choices

At 31-W Insulation, we believe that the more you know, the better position you are in to decide what type of insulation is best for your Garner, North Carolina home. In addition to pointing out that there are two foam insulation choices – open cell and closed cell – we want to go further into the discussion to explain the differences between them. Of course, when you contact us to provide insulation for your home, we’ll go into more detail and discuss your foam insulation choices based on your specific project and objectives.

  • Cell Difference- Closed cells are closed, as the name suggests, and open cells are not completely encapsulated. The result is that open cell foam insulation is flexible and easier to get into tight spaces, whereas closed cell insulation is rigid, providing structural support as well as insulative properties.
  • R-Value- While the R-value of your foam insulation can vary depending on the brand used, typically you’ll get between 6.5 and 7 R-value from closed cell foam and about 3.5 R-value from open cell foam per inch.
  • Density- The density of open cell foam is roughly 0.5 pounds per cubic foot, whereas closed cell foam is 1.75 pounds per cubic foot or more.
  • Expansion- Open cell foam expands to 3” of thickness, making it ideal for inside walls where one application is desired. Closed cell foam expands to 1” of thickness with each application, but multiple applications can be applied when a higher R-value is desired.
