While fiberglass used to be the material of choice for those looking to insulate their homes or places of business, there are now many more options available. You’ve probably heard about the benefits of spray foam insulation, a fantastic choice for various uses. In addition, spray foam insulation has a higher R-Value but is also resistant to mold and has the most increased soundproofing capabilities. The spray foam insulation option is yet another choice.

There are two different varieties of spray foam: closed-cell foam and open-cell foam. Here at 613 Spray Foam, we strive to help you choose the best for your needs.

What Is Closed-Cell Spray Foam?

Blowing liquid chemicals together create closed-cell insulation. The gases these chemicals produce will expand like in open-cell foam; however, they grow slower, and the foam sets before the bubbles begin to pop. It makes the foam dense and less porous compared to open-cell foam.

The Pros and Cons of Closed-Cell Foam


  • Closed cells have a greater R-Value.
  • Closed cells can use at lower temperatures.
  • Closed-cell is the ideal choice for flood zones since it blocks large quantities of water.
  • Closed cells are suitable for outdoor and indoor use.
  • Closed-cell construction increases structural strength.


  • Closed cells cost more than open-cell.
  • Closed-cell cells are denser than open-cell and, as a result, require more components.

When Is Closed-Cell Foam Preferable Over Open-Cell Foam?

Open-cell and closed-cell spray foam insulation have both advantages and disadvantages. The best choice to suit your needs will depend on the specifics of the task at hand. There is some overlap in the range of uses for which closed-cell and open-cell foam are suitable. Still, generally speaking, one has a definite advantage over the other. There are various applications for closed-cell foam, including:

  • Vented and unvented Attics
  • Internal or External Walls
  • Floors
  • Unvented Crawl Spaces
  • Concrete Slabs
  • Cold Storage
  • Freezers
  • Ducts
  • Coolers
  • Tanks
  • Ceilings
