Why Should You Use Spray Foam Insulation In New Orleans and South Louisiana
This question deserves one simple answer, polyurethane foam insulations, when properly installed, outperform in a very "real world way" any other traditional insulation product on the market.
There are so many insulation products to choose from, all of which are quoted in terms of R-value. However, what we are never taught is that the term R-value is a misunderstood concept and a poor indication of the true performance of the insulating abilities of the product. The fact is R-value is determined based on very controlled experimental conditions where real life forces are intentionally neglected to be factored in.
The two most distorting of these forces are convection (air-flow) and water vapor (moisture), both which greatly reduce the potential effects of the insulation product. With breezy days, while running exhaust systems in the house, and running the central air-conditioning system the majority of homes are experiencing states of pressurization or depressurization. Also, our sub-tropical climate normally presents a high level of moisture content in the air. The majority of insulation products have their experimentally determined R-values reduced down into fractions...even quite possibly to zero with the introduction of these two forces.
Polyurethane foam will greatly outperform the competing insulations by reducing air flow and the transfer of water vapor. Products such as closed cell foam will even eliminate these forces altogether.
The demand for traditional products such as fiberglass, cellulose, Styrofoam, rockwool, among many others, is quickly diminishing as these facts are discovered. In fact, building code in some counties around the nation are already adopting such strict energy efficiency policies that it is almost impossible to meet energy code if not using products such as closed cell polyurethane foam.
As Certified Energy Rater Jeff Haag states, "In studying and testing the performance of insulation products after installation in thousands of homes since 1999 I will very comfortably state that no other insulation product has ever outperformed polyurethane foam. If the future of our country's insulation practices follows behind other more advanced markets such as Canada, Australia, Europe, Northern American states, etc. it is only a matter of another decade or so that the fiberglass industry will lose their market advantage and begin selling polyurethane foam. In the meantime we will continue educating Louisiana homeowners and business owners of the importance of these products."

The majority of spray polyurethane foam products are sold based on a great deal of misleading information. It is the purpose of EnviroGreen Insulation to present the viewer of this website with all the available facts which will allow a greater education of these products.
The R-value is a modern fairy tale. It's a fairy tale that has been so touted to the American consumer that it now has a chiseled in-stone status. But the saddest part of this fairy tale is that the R-value by itself is almost a worthless number.
