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)

  • 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

  • Lower vapor permeance (can be a Class II VDR)

  • Higher tensile and bond strength
