About Density

Density refers to the approximate weight of a 1′ x 1′ x 1′ cube of fully cured foam (2 or 4 pounds). Higher density foams typically do not expand as much as lower density foams, resulting in a denser and heavier foam. Higher density foams typically produce less yield than lower density foams.
