There are so many insulation solutions available today.
While it used to be that fiberglass was the go-to option for most people looking to insulate their home or business, today, you have many more choices than you used to. In a previous blog, we compared three of the most common types of insulation — fiberglass, cellulose and spray foam. If you’ve had a chance to read it, then you probably already know that spray foam insulation is a great choice for many different applications. Not only does spray foam insulation have a higher R-Value, but it’s also resistant to mold and has next-level soundproofing abilities. However, once you choose to go with spray foam insulation, you still have one final choice to make.
There are actually two different kinds of spray foam to choose from — closed cell foam and open-cell foam — and here at 360 Thermal, we are dedicated to helping you find the right option for your needs. In this blog series, we’re carefully examining both types of insulation to help you determine which is best for you, and in Part 1, we went over open-cell foam. Keep reading to learn about closed-cell spray foam insulation.
What is closed-cell spray foam?
Closed-cell insulation utilizes chemical blowing agents in a liquid form. The gasses these chemicals create will expand, much like they do in open-cell foam, but they expand much slower and the plastic sets before the bubbles start to burst. This results in a foam that is much denser and more impermeable than open-cell foam.
The Pros and Cons of Closed-Cell Foam
- Closed-cell has a higher R-Value.
- Closed-cell can be applied at low temperatures.
- Closed-cell is ideal for flood zones because it is designed to reject bulk water.
- Closed-cell is ideal for both interior and exterior use.
- Closed-cell increases structural strength.
- Closed-cell is more expensive than open-cell.
- Closed-cell is denser than open-cell and, therefore, requires more materials.
When should you use closed-cell foam over open-cell?
Closed-cell and open-cell spray foam insulation both have pros and cons, and the right one for your needs will depend on the nature of the project at hand. Although there is some overlap between applications that closed-cell and open-cell foam can be used for, in most cases, one is clearly more beneficial than the other. Closed-cell spray foam can be used for many applications, including:
- Vented and Unvented Attics
- Interior or Exterior Walls
- Unvented Crawl Spaces
- Concrete Slabs
- Cold Storage
