Open Cell Vs. Closed Cell Foam Insulation

Differences In Open Cell Vs. Closed Cell Foam Insulation

Open cell foam is porous. It has tiny cells that don’t close. It appears sponge-like and provides great air and sound resistance; but water can still make its way through, so it is not recommended for outdoor usage. Closed cell foam insulation has cells that are completely closed and seal out water. It’s much tougher and more rigid, so it can be used outdoors.

Open Cell and Closed Cell foam both have strong benefits. Because of the strengths and weaknesses of each product, one might be a better match for your project than the other. Our skilled and experienced team can help you determine which way to go.


  • Open Cell Foam Insulation – Because it requires fewer ingredients to create, open cell foam is affordable. While it doesn’t have as high of an R-value as closed cell, it is still far more effective and energy efficient than the other traditional products. And depending on the scale of your project, it can still end up being much more affordable than closed cell. It is also considered to be more environmentally friendly.
  • Closed Cell Foam Insulation – With a high R-value, easy installation, and impermeability for water and air, closed cell is a top choice for home and commercial installation. It is even a popular product for flat roofing. It has a very rigid form, so it can add to the stability of a structure.
