They are produced by the division of monocytes. Foam cells are formed when the body sends macrophages to the location of a fatty deposit on the blood vessel walls. The macrophage surrounds the fatty material in an attempt to destroy it. The cell becomes filled with lipids. The lipids surrounded by the macrophage give it a âfoamyâ appearance.
Spray Foam is categorized into two types, open-cell or closed-cellâ. Open cell is lightweight foam that is flexible, and an excellent air barrier. Open cell foams most commonly range from .5 lb to .7lb densities. Closed cell foam is higher density foam, and a moisture barrier. Most closed cell foam used for insulation range from 1.7 lb to 2 lb. Closed cell foam can go up to 3 lb density which is often used in exterior roof applications (like the Superdome). The main differences between open and closed cell foam are moisture permeability, R-Value, and flexibility. Closed cell foam is a moisture vapor barrier. What this means is that it will not allow moisture to pass through the foam. Open cell foam is not a moisture vapor barrier, and will allow moisture to pass.
