Benefits of Open-Cell Spray Foam Insulation

If you are looking to move forward with our Raleigh open-cell spray foam, you may be wondering what benefits it possesses. Open-cell spray foam has a density of about 0.5 lb. per cubic foot and an R-value of 3.5 or 3.6 per inch. Open-cell spray foam has the ability to expand 120 times its initial size, allowing the insulation to go in all the nooks and crannies of your space. It is a great air barrier and can work its way into all wall cavities. This type of foam is relatively vapor-permeable and is made of bio-based raw materials. Open-cell foams primarily use water as the blowing agent.


At MPI Foam, our open-cell foam insulation goes the extra mile.

  • It uses significantly fewer insulation materials, making it a prime choice from a resource-use standpoint.
  • It is suitable for interior insulation and is less costly than closed-cell foam.
  • Open-cell insulation is a soft, sponge-like texture that retains a continual air barrier throughout the building’s structural movement and setting. 
  • It lets bulk water pass through it through bi-directional drying that eliminates the chance of condensation and mold growth.
  • Open-cell insulation will allow water to wick in the event of a leak.
