Facts about Spray Foam Insulation

The contractor simply makes a base out of wood, covers it with wire or something else that the foam may adhere to, and sprays the foam on until the desired thickness is reached. The builder will then carve, sand, and cut the foam until it has the perfect shape and texture. Spray foam has been used for a variety of purposes, including building, entertainment, sound deadening, buoyancy, HVAC, filling voids, emergency flood control, hazmat clean-up, and even theatrical uses.Do you want to learn more?read here

There are certainly a couple more uses for spray foam, but we’ll leave it up to you to figure out what they are. While spray foam insulation as we know it today first appeared in the 1980s, its origins can be traced back several decades, starting with Otto Bayer’s invention of polyurethane foam in the 1940s. In the late 1930s, an industrial chemist called Otto Bayer started experimenting with polyurethane in Germany. David Eynon, the president of Mobay, a war effort conglomerate formed by the merger of two chemical industry behemoths, Monsanto and the Bayer Corporation, introduced this technology to the United States in the early 1940s. Despite working for Bayer Corporation, Otto Bayer was not linked to the company’s founders. Polyurethane polymers were primarily used in military and aircraft applications during the 1940s. For the period of World War II, most of the applications of these high-grade plastic polymers were driven by the manufacture of war machines. Polyurethane was not used as a home insulation material until the 1950s. The invention of the “Blendometer” paved the way for polyurethane’s extension into the world of home insulation. Walter Baughman invented the Blendometer in 1953, which was the first computer capable of mixing components for the production of polyurethane foam. The Blendometer allowed for the strategic mixing of chemicals to produce a plastic elastomer or expanding foam, as Baughman called it. When applied as a liquid, this plastic elastomer expanded into a dense foam that hardened after drying.
