Spray Polyurethane Foam
Open or Closed Celled?
The choice between open-cell and closed-cell polyurethane foam insulation depends on several factors, including the project requirements, budget, and personal preferences. Here are some key differences between the two options:
Open-Cell Polyurethane Foam:
-
Is less dense than closed-cell foam, making it softer and more flexible
-
Has a lower R-value per inch than closed-cell foam, which means it may require thicker layers to achieve the same level of insulation
-
Provides excellent sound dampening and air sealing, making it a good option for interior walls and ceilings
-
Is typically less expensive than closed-cell foam, which can make it a more attractive option for some homeowners or commercial property owners


Closed-Cell Polyurethane Foam:
Overall...
Both open-cell and closed-cell polyurethane foam insulation are effective at providing energy efficiency, reducing energy costs, and improving indoor air quality. The choice between the two ultimately depends on the specific needs and requirements of your project. Let CSI the Spray insulation experts help you determine which option is best for your property.
