Although spray foam insulation as we know it today truly emerged during the 1980s, spray foam actually does have its roots several decades further before, starting with the creation of polyurethane foam in the 1940s by Otto Bayer.
Otto Bayer, a commercial chemist, actually began utilizing polyurethane in Germany in the late 1930s. This technology was delivered to the us during the early 1940s by David Eynon, the president of Mobay, a war effort conglomerate produced from the partnering of two chemical industry giants, Monsanto plus the Bayer Corporation. Although Otto Bayer worked for Bayer Corporation, he was not relevant to the company's founding family.
During the 1940s, polyurethane polymers were used primarily in military and aviation applications. The creation of war machines for the World War 2 conflict drove almost all of the applications of extremely high-grade plastic polymers for the duration of the war.
It absolutely was not until the 1950s that polyurethane began for use in home insulation. It absolutely was the invention from the "Blendometer" that allowed for increase of polyurethane application for the home insulation realm. The Blendometer was the primary machine able to mix components for the creation of polyurethane foam and was designed by Walter Baughman in 1953.
The Blendometer allowed for the strategic mixing of chemicals to generate what Baughman referred to as a plastic elastomer or an expanding foam. Liquid when applied, this plastic elastomer expanded right into a thick foam and finally hardened upon drying.
Baughman's Blendometer was still a partially manual process, with humans tilting trays of chemicals to blend foam. Whilst the machine did provide for the usage of polyurethane in home insulation plus in other home-related applications, like ac insulation, it was actually still a technology in its infancy and something that made widespread application of polyurethane as a residential insulation material no less cumbersome.
Polyurethane polymers were utilized in a number of means throughout the following decades, with incredible advancements being built in the auto industry applications of the material for example. However, it might be more than two decades before the foam would become commonly used home based insulation processes.
Building on Baughman's invention, the initial dedicated spray technology machine was constructed in 1963 by Fred Gusmer. The 1960s and 1970s saw technological advancements which made spray foam's utilize in home insulation more easily achievable and affordable.
It absolutely was also from the 1970s that the concept of the "super insulated" home emerged. Largely driven via the energy crisis with the 1970s, home builders and homeowners alike began to search for methods to boost the energy efficiency of homes.
The crisis fueled advancements in technology that laid the building blocks for modern spray foam applications. It was the roll-out of advanced spray nozzle technology that allowed spray foam insulation to be utilized widely home based construction and improvement projects.
spray foam insulation ct foam nozzle allows the foam mixture and also the chemical liable for its expansion capabilities being separated until just just before application. The spray foam mixture is made of several key components yet it is the expansion chemical, isosynate, which is responsible for its easy application and expansive character.
The application nozzle allows the foam mixture plus the isosynate to get shipped to the nozzle through separate hoses, mixing only seconds prior to being sprayed. The spray foam arrives at its destination as being a liquid but quickly expands in to a foam substance and later on dries in 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 advantages of closed verses open foam insulation so that as some companies aimed to market water blown foam application processes.
Though there has been much debate within the industry, R-value standards, used being a way of measuring determining energy efficiency, have cleared up a great deal of the controversy. R-value ratings clearly define closed foam as the very best method of generating a home as energy-efficient as you can.
Closed cell spray foam has additionally been included with a list of creating requirements for creating homes in hurricane and earthquake zones more structurally sound. The improved stability of homes insulated with spray foam technology makes the use of spray foam a sensible move for just about any homeowner irrespective of geographic location.
