Spray Foam Insulation – History and Facts

Tweet

Spray foam insulation in Kansas is a different, newer method of insulation than the traditional building insulation. "Although spray foam insulation as we know it today truly emerged in the 1980s, spray foam actually has its roots several decades further in the past, beginning with the development of polyurethane foam in the 1940s by Otto Bayer." Otto Bayer, began working with polyurethane in Germany during the late 1930s, this technology was then brought to the United States in the early 1940s. In the 1950s polyurethane began to be used in home insulation. In the 1960s and 1970s there were many technological advancements; these advances made spray foam's use in home insulation more easily achievable and affordable. Spray foam comes in different types but can be categorized in two types, open cell and closed cell. Open Cell Open cell is the type of foam where the cells are almost closed, but not completely closed. It is less expensive because it uses fewer chemicals. This type of foam is not used for outdoor applications. It is used for interior walls because it provides reduction in sound. Closed Cell Closed cell foam is denser than open cell foam. This type of cell is more often used in roofing projects and other outdoor applications. This type can be used anywhere in a house. Benefits of Spray Foam Spray foam saves energy costs. "Studies by the US Department of Energy show that 40% of a home's energy is lost as the result of air infiltration through walls, windows and doorways. Buildings treated with spray foam insulation typically insulate as much as 50% better than traditional insulation products." Disadvantages of Spray Foam Isocyanates are irritants to the eyes, gastrointestinal and the respiratory tract. Direct skin contact with isocyanates may cause inflammation. Some people break out in rashes on their arms, chest, and neck. Workers should not be overexposed to isocyanates. There are many systems used to apply spray foam. All types of insulation stop a large amount of energy loss. Insulation also saves energy in hot climates by reducing air conditioning use. Spray foam insulation levels vary, with some providing up to an R-value of 6.7 per inch - http://sprayfoamsolutionsks.com/services/
