Spray Foam Insulation is a two-part device that usually includes petroleum oils, plastics, and resins. There are two types of polyurethane foam: open cell and closed cell foam. Polyurethane spray foam is a highly adaptable material that comes with a wide range of physical properties and densities. While the chemical structures of the two forms of foam are somewhat similar, their properties and capabilities vary in several respects, necessitating the user’s understanding of the differences in order to decide which foam is best for their particular application.

The density of open cell spray foam insulation is 0.5 pound per cubic foot. The foam can become heavier or stronger as its density increases. Because of the existence of the chemical reaction during the installation process, this form of polyurethane foam is referred to as “Open Cell.” The tiny cells of the polyurethane foam are split as it is applied, allowing air to fill the “free” space within the material, resulting in a soft or spongy material. The R-Value of the open cell foam is 5 to 5.5 per inch (R-Value is the measure of thermal resistance, which can be found by identifying the ratio of the temperature difference across an insulator and the heat flux). When doing the same sized job, 0.5lb. foam products use considerably less material than 2lb. foam products, making them appealing to those concerned about foam waste. Since open cell foam uses less material, the project would be much less expensive than if closed cell foam is used. While open cell foam is a cost-effective and efficient product, it has some drawbacks when compared to closed cell foam. One of the drawbacks of open cell foam is that it has a lower R-Valuer per square inch than closed cell foam, and it is vapour permeable, so it must be coated with a vapour retardant film. Open cell foam has been recognised as an excellent insulator, air sealant, and sound barrier, despite its advantages and disadvantages.
“Closed-cell” or “2 lb foam” is the name given to the second form of polyurethane foam. The chemical reaction that gives closed cell foam its name is what gives it its name. The tiny cells formed during the chemical reaction are not split during the installation process and are packed together. These tiny cells are packed with gas, which causes the material to rise and become a good insulator. As previously stated, the higher the density of the foam, the heavier and stronger the foam would become. This form of foam has a dense enough density to increase the structural integrity of the structure to which it is applied.
