The Evolution of Spray Foam Insulation

As anyone in the industry is aware, spray foam insulation products have been instrumental in improving the energy efficiency of buildings, sealing out moisture and preventing mold, and even strengthening structural integrity. The miracle product is prized for its environmental benefits — through research by their Energy Star Program, the Environmental Protection Agency has concluded that adding insulation and properly sealing air leaks could reduce monthly energy bills by up to 20%, improving sustainability and saving owners money. Furthermore, spray foam insulation products’ inert chemical composition makes it highly resistant to degradation, meaning that the product can continue to be effective for decades. But just how was this incredible technology developed?

The History of Spray Foam Insulation Equipment

The inception and the continued development of spray foam insulation products took place from around the 1940s up to the ’80s. Initially, spray insulation was made possible by the work of German industrial chemist Otto Bayer, who pioneered the first technique to produce polyurethanes from the polyaddition of polyisocyanate and polyol. Dave Eynon, head of American war effort corporation Mobay, soon learned of the breakthrough and utilized it for U.S. military applications.

This remained the primary application for spray foam tools and equipment for the next decade until Walter Baughman realized their potential for home improvement. Called the “Blendometer,” his device allowed early adopters of the technology to insulate their homes with the hardening and expanding polymer. However, the manual mixing that the machine required meant that it did not closely resemble the advanced, automatic spray foam insulation products of today.

While spray foam was still mainly used throughout the ’50s in commercial applications such as the auto industry, Fred Gusmer in the ’60s improved upon Baughman’s design and again returned attention to the technology’s home applications. This trend has continued to this day, with innovators constantly working to improve spray foam technology. Spray Foam Systems is at the forefront of this industry.
