The benefits of open-cell spray foam

As mentioned, open-cell foaming insulation is best suited for interior applications, offering an array of advantages of traditional fibrous insulation materials. Benefits of open-cell foam insulation include:

  • Allows for bi-directional drying
  • Can accommodate long-term creep and seasonal movement
  • Can be installed at a significantly lower cost and target the same specified R-value*
  • Is not considered a food source for mold
  • Provides sound dampening qualities, ideal for use media or theater rooms
  • Lower installed cost, per square foot

The benefits of closed-cell insulation foam

While open-cell foamed insulation has many benefits over traditional insulation types, closed-cell sprayed-in insulation goes beyond to offer additional advantages.  Although closed-cell sprayed insulation foam has a higher per board foot cost, there are benefits that the material offers including:

  • Ability to reject bulk water (closed-cell foam insulation is recognized as a flood resistant material by FEMA(link is external))
  • Can be applied at very low temperatures (as low as 5°F)
  • Adds wall racking strength as well as impact resistance
  • Higher R-value* per inch  – easier to accommodate high R-value* requirements in narrow spaces
  • Higher tensile and bond strength
