A spray insulation is referred to open cell or closed cell because of the difference between the small bubbles cells that make up the foam.
In other words the cells are deliberatly left open.
This makes the foam a softer more flexable material.
Closed cell products may be based on elastomeric polymers glass or foamed plastics such as polyolefin polystyrene or polyurethane.
Choose this option for areas that need a good amount of strength and water resistance.
Each type is used in a variety of applications and under conditions where resistance to water and moisture is critical.
