Understanding the Differences Between Open-Cell Spray Foam and Closed-Cell Spray Foam

The many benefits of polyurethane spray foam make it a widely accepted insulation method for a wide variety of uses, including insulating residential properties. If you are considering this material for your home, you’ll find that you have two choices – open-cell and closed-cell. It will benefit you to have an understanding of the differences so that you can proceed with the one that makes the most sense for your situation.

Open-cell spray foam is more affordable than closed-cell spray foam

Closed-Cell Spray Foam

The density of closed-cell spray foam makes it the more common choice of the two types of spray foam. Being denser means you can accomplish a higher R-value, which is a measurement system for resistance against heat flow. Closed-cell spray foam is also exceptional for preventing moisture migration, which could result in humidity issues like mold. It is also a strong material that aids in strengthening the walls to which it is applied.

Open-Cell Spray Foam

Although open-cell spray foam has a lower R-value, it can be the ideal solution when needing to reach areas that are difficult to access. It expands once applied, making it perfect for filling in wall and ceiling cavities. It is dense enough to provide a decent amount of insulation. Open-cell spray foam is more affordable than closed-cell spray foam, so it can be a viable solution despite its lack of some of the benefits of closed-cell spray foam.
