Closed-cell spray foam & open-cell spray foam – understanding the advantages

Closed-cell spray foam and open-cell spray foam insulation materials can be used effectively within a commercial building design. Whether your design goals include energy efficiency, visual appeal or long-term performance, both closed-cell spray foam and open-cell spray foam afford you opportunities to create commercial buildings that work. Closed-cell spray foam is ideal for continuous insulation on the exterior while open-cell spray foam offers tremendous performance on the interior at a lower installation cost.

Closed-cell spray foam exterior applications

  • Can be applied at very low temperatures (as low as -15oC)
  • High thermal resistance per thickness
  • Ideal for continuous insulation solutions
  • Lower vapour permeance
  • Can reject bulk water (ideal for flood zones or areas prone to high snowfall)
  • Higher tensile and bond strength

Open-cell spray foam interior applications

  • Can be installed at a significantly lower cost and target the same specified RSI-value
  • Lower raw material/resource use
  • Permits bi-directional drying
  • Will accommodate long-term creep and seasonal movement
  • Hydrophobic material
  • Air barrier and insulating material
