Spray Foam Insulation: Open Cell vs. Closed Cell

Spray foam insulation is an excellent option for home insulation. The next step is to decide if you would like to use open cell or closed cell. But what’s the difference? Our team at ARC Insulation is prepared to guide you through the differences to help you make your decision.

Spray foam insulation is an excellent option for home insulation

  • Open Cell – Open cell spray foam has open cells. This makes the foam soft and more elastic. Because of this, the foam expands, making it able to cover those hard-to-reach areas. Open cell insulation is also a great option for soundproofing. One application is able to fill any open areas between studs. At the end of the day, open cell spray foam insulation is an affordable option opposed to closed cell. However, closed cell will give your home more sustainable insulation.
  • Closed Cell – Closed cell spray foam has completely closed cells. As these cells are sealed together, they prevent air and moisture from intruding in the insulation. For this reason, closed cell spray foam insulation is more sustainable than open cell spray foam insulation. Closed cell has twice the R-value as open cell.  All in all, closed cell is typically the safest option, although it has a higher price tag compared to open cell.
