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
I didn't realize the difference between foam and the softer foam depends on whether it's "open cell" or "closed cell"... Very interesting! I'm hoping my roofer Portland can get one of the two component kits for my house. Thanks for sharing this!
ReplyDeleteI had no idea that there were this many different kind of roofing techniques. This is really interesting. In a few years, it will be time for me to get a new roof. Thanks for the great article!
ReplyDeleteVery well said. Highly trained staff translates into quality workmanship.
