“Closed Cell” vs “Open Cell” Spray Foam.

The Difference Between Closed Cell and Open Cell Spray Foam Explained.

If you’re in the market for spray foam insulation, you’ve probably come across the terms “closed cell” and “open cell” spray foam. While both types of foam offer superior insulation properties, there are some significant differences between the two.

Closed Cell Spray Foam

Closed cell spray foam is a dense foam that is formed by mixing two chemicals together, causing them to expand and harden. Closed cell foam has a higher R-value than open cell foam, meaning it offers better insulation. It is also more resistant to moisture and air infiltration, making it ideal for use in areas that are prone to moisture or where airtightness is crucial. Closed cell foam is more expensive than open cell foam, but it offers superior insulation and can provide significant energy savings over time.

Open Cell Spray Foam

Open cell spray foam is a lighter foam that is also formed by mixing two chemicals together. Unlike closed cell foam, open cell foam is less dense, allowing it to expand more and fill in gaps and crevices more effectively. While it has a lower R-value than closed cell foam, it is still an effective insulator and is often used in areas where cost is a primary consideration. It is also easier to install and can be used for soundproofing purposes.

Which Type of Spray Foam is Better?

The answer to this question depends on the specific application. In general, closed cell foam is better suited for areas that require higher R-values or where moisture or airtightness is a concern. This includes areas like roofs, crawl spaces, and exterior walls. Open cell foam, on the other hand, is better suited for interior walls, attics, and other areas where cost is a primary concern.

When choosing between closed cell and open cell spray foam, it’s important to work with a reputable contractor who can help you determine the best solution for your specific needs. By taking into account factors like your budget, location, and insulation requirements, you can ensure that you choose the right type of spray foam for your project.

In conclusion, closed cell spray foam and open cell spray foam offer different benefits and are better suited for different applications. By understanding the differences between the two, you can make an informed decision and choose the right type of spray foam for your specific needs.
