Differences Between Open and Closed Cell Foam

The most obvious distinction between these two types of foam is that one contains tiny spaces, or cells, that are entirely closed and confined, while the other has open cells. However, look more closely at the differences between open-cell and closed-cell foam.

Open Cell Foam

When more than half of a foam’s cells are open, the foam is referred to as having open cells. Foam with open cells responds more like a spring. Because of the unrestricted airflow, when squeezed, it can swiftly revert to its initial state. Moreover, an open cell is flexible, breathable, and easily conforms to objects.

Benefits of Using Open-Cell Foam:

  • Light – Open cell foam generally weighs about 1.2 to 2.8 lbs per cubic foot.
  • Flexible – open-cell foam can grow and shrink in hot or cold climates.
  • Sound Reduction – dampens the sound of outdoor activities

Drawbacks of Open-Cell Foam:

  • Open-cell foams have a lower R-value and are unsuitable for use in extreme climates.
  • They are only sometimes dense enough to provide rigid structural support.
  • Open-cell foams diminish over time, depending on their conditions.

Closed-Cell Foam

Walls surround the cells in closed-cell foam and do not connect to other cells because they are closed. This foam is frequently produced using a rubber compound that has been highly pressurized and exposed to a gas, such as nitrogen. This foam form is incredibly resilient and produces higher densities because of these distinct gas pockets.

Benefits of Using Closed-Cell Foam:

  • Largely waterproof. Cells are so tightly packed, leaving little room for water.
  • Durable and tear-resistant for long-lasting results.
  • Superior insulation with an air barrier

Drawbacks of Using Closed-Cell Foam:

  • Increased density can lead to breaks.
  • Less breathability than open-cell foam.
