Open cell spray foam insulation is mostly used for interior applications.
If you are familiar with polyurethane spray foam insulation, you know that there are two types, namely closed cell and open cell spray foam insulation. Both systems of spray foam insulation offer significant advantages over fiberglass batts. These include the ability to fill gaps and oddly shaped cavities, plus the ability to retain shape over extended periods of time and adverse conditions. At Cape Fear Foam LLC, since 2006, we have offered not only superior spray foam products, but also shared our knowledge and experience so the right type is used for the project involved.
Closed cell foam insulation has the thermal insulation value (known as the R-value) that brings your home up to Energy Star standards, with only one half the thickness required for fiber insulation. It can provide an R-value of 6 per inch of material. Additionally, closed cell foam products increase the strength of your walls (about double the strength) and greatly increase the water resistance of your home exterior. It is the ideal option for exterior applications.
On the other hand, open cell foam insulation is a lower-cost option that is best used for interior applications. If you are looking to create an R-value of about 3.7 per inch of material, such as to accommodate seasonal shifting and dampen sounds, this is the option we recommend. It can also be used when there aren’t space restrictions as it takes more open cell foam insulation to achieve the same R-value compared to closed cell foam insulation.
