What are the differences between the foam densities?
The densities of the foam refer to the weight of the foam when cured per cubic foot (12″ x 12″ x 12″). Higher densities will result in a heavier foam which is also stronger. We have listed brief examples of hardness and physical properties to help you select the correct density here. Please also be aware that as you increase in density your expansion ratio will decrease, resulting in a higher cost per cubic foot of cured foam.
