Although spray foam insulation as we know it today truly emerged within the 1980s, spray foam actually have their roots several decades further in the past, beginning with the introduction of polyurethane foam from the 1940s by Otto Bayer. Otto Bayer, a commercial chemist, actually began utilizing polyurethane in Germany through the late 1930s. This technology was taken to america in the early 1940s by David Eynon, the president of Mobay, a war effort conglomerate created from the partnering of two chemical industry giants, Monsanto plus the Bayer Corporation. Although Otto Bayer worked for Bayer Corporation, he had not been relevant to the company's founding family. Over the 1940s, polyurethane polymers were used primarily in military and aviation applications. The production of war machines for any World War 2 conflict drove most of the uses of these high-grade plastic polymers for the duration of the war. It had been not until the 1950s that polyurethane began to be utilized home based insulation. It was the invention of the "Blendometer" that allowed for increase of polyurethane application towards the home insulation realm. The Blendometer was the 1st machine able to mix components for the roll-out of polyurethane foam and came to be by Walter Baughman in 1953. The Blendometer allowed to the strategic mixing of chemicals to create what Baughman referred to as a plastic elastomer or an expanding foam. Liquid when applied, this plastic elastomer expanded in a thick foam and finally hardened upon drying. Baughman's Blendometer was still a partially manual process, with humans tilting trays of chemicals to mix foam. While the machine did accommodate the usage of polyurethane in home based insulation also in other home-related applications, like air conditioning equipment insulation, it absolutely was still a technology in their infancy then one that made widespread usage of polyurethane as being a residential insulation material no less cumbersome. Polyurethane polymers were used in a variety of means during the entire following decades, with incredible advancements being manufactured in the auto industry applications of the fabric for example. However, it will be more than two decades prior to the foam would become traditionally used in home insulation processes. Building on Baughman's invention, the 1st dedicated spray technology machine was constructed in 1963 by Fred Gusmer. The 1960s and 1970s saw technological advancements which made spray foam's use within home insulation quicker achievable and affordable. It absolutely was also during the 1970s that the thought of the "super insulated" home emerged. Largely driven via the energy crisis with the 1970s, home builders and homeowners alike began to search for strategies to boost the energy efficiency of homes. The crisis fueled advancements in technology that laid the building blocks for modern spray foam applications. It turned out the development of advanced spray nozzle technology that allowed spray foam insulation to use widely home based construction and improvement projects. spray foam insulation company ri foam nozzle allows the foam mixture and also the chemical responsible for its expansion capabilities to become separated until just previous to application. The spray foam mixture contains several key components yet it is the expansion chemical, isosynate, which is accountable for its easy application and expansive character. The application nozzle allows the foam mixture plus the isosynate being sent to the nozzle through separate hoses, mixing only seconds before being sprayed. The spray foam arrives at its destination to be a liquid but quickly expands into a foam substance and later dries right into a hardened plastic upon curing. The 1980s and early 1990s saw significant amounts of controversy in the spray foam insulation industry as different marketing schemes from various companies promoted the benefits of closed verses open foam insulation and also as some companies aimed to market water blown foam application processes. Though there has been much debate in the industry, R-value standards, used like a measure of determining energy efficiency, have cleared up much of the controversy. R-value ratings clearly define closed foam as the most efficient way of setting up a home as energy-efficient as it can be. Closed cell spray foam has additionally been included in their list of creating requirements in making homes in hurricane and earthquake zones more structurally sound. The improved stability of homes insulated with spray foam technology makes the application of spray foam an intelligent move for virtually any homeowner regardless of geographic location.
