Q. Some Foams Are Made From Soy, Are They Better?
A. Soy and other agriculturally derived foams have gained tremendous popularity over traditional petroleum based foams as the demand for ‘green’ building products increases. Agricultural foams help support renewable resources and the American farmer. These foams derive some of their polyols from agricultural resources rather than solely from petroleum. Agricultural polyols have been in use for a long time, and are used to make everyday plastics from lawn chairs, car seats, to foam insulation. However, the total content of agricultural polyols can vary greatly from one spray foam manufacturer to another. Even with these agricultural contents, the majority of the foam is still made from petroleum or recycled plastic contents. It is most important to select a brand based on reputation and quality; agricultural contents do not necessarily ensure a better product. Buyer beware, some manufacturers use an insignificant quantity of agricultural polyols in order to tout their product as ‘green.’
