Closed-cell foam, on the other hand, is made up of cells completely closed and packed together. They are filled with a gas that forces the foam to rise and expand which makes it a greater insulator.
Closed-cell foam has a greater R value, is stronger and it has a better resistance to the leakage of air and water vapor. The higher the density the foam, the heavier, or stronger it becomes.
For mid-size jobs in homes, there are low pressure (< 250 pounds per inch) two-component kits for SPF projects. These are used to insulate small areas by SPF foam contractors who use special personal protective equipment.

Commercial applications and other large renovations use two-component, high pressure systems (800-1600 psi) with 55-gallon drums and a spray rig. This product is applied by contractors who have had special training and use specialized personal protective equipment, including respirators.
Washington Roofing & Insulation uses BASF Closed Cell Spray Foam and the staff is trained and certified for SPF commercial projects. For more information, visit our website or contact us at 800.383.3062
