Open-Cell Spray Foam

Do you need to insulate a home or commercial building with spray foam? If you’re located in the San Antonio, Texas area, get in touch with Installed Building Products San Antonio. We work with homeowners and builders on both retrofit and new construction insulation projects.

Open-Cell Foam Installation

One of the most widely installed types of insulation, spray foam is used for both residential and commercial projects. The two main types of spray foam insulation are closed-cell and open-cell. Open-cell is a type of foam where the tiny cells are not completely closed. Open-cell foam cells are less dense and filled with air, which gives the insulation a spongy texture and a lower R-value (although it can achieve a greater R-value if not restricted by space). Low-density, open-cell polyurethane foams are similar to conventional polyurethane foams but more flexible. In general, open-cell spray foam insulation:

  • Helps provide an air barrier but doesn’t offer a water vapor barrier
  • Is frequently used for interior walls because it can help with soundproofing
  • Can be less expensive

The professionals at IBP San Antonio install CertainTeed CertaSpray® and BASF open-cell spray foam.


Polyurethane open-cell foam, which contains a low-conductivity gas in its cells, has an R-value ranging from R-5.5 to R-6.5 per inch. Open-cell insulation cells are filled with air and less dense, so they have lower R-values than closed-cell insulation.
