What is the difference between open cell and closed cell?

What is the difference between open cell and closed cellWhen it comes time to actually put spray foam insulation in your home or commercial building, you must decide whether you will use 0.5 lb./cubic foot., open cell foam, or 2.0 lb./cubic foot. closed cell foam. This makes a big difference in material cost, how the foam is applied, and the overall performance.

The Foam density is measured by weighing one solid cubic foot of foam material.

Open Cell spray foam has tiny cells in the foam that are not completely closed. They are broken and air fills all of the “open” space inside the material. This makes the foam weaker or softer feeling than closed-cell foam.

Closed Cell spray foam differs in that all of its tiny foam cells are closed and packed together. They are filled with a gas that helps the foam rise and expand and become a greater insulator.
