Most of the energy costs spent to keep a Downtown home warm in the winter and cool in the summer end up leaving through the attic. In the summer, the sun’s heat pours in through the attic and in the winter, warm air rises past the ceiling and out of the home. Saving on energy costs starts in the attic, but how much insulation is enough?

Although spray foam insulation as we know it today truly emerged in the 1980s around the Downtown area, 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, an industrial chemist, actually began working with polyurethane in Germany during the late 1930s. This technology was brought to the United States 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 and the Bayer Corporation.
How Much Attic Insulation is Enough?
An energy efficient home is an environmentally sound home and to achieve energy efficiency insulation is vital. It must be used liberally, and it must be properly installed. There are all sorts of insulating materials, and their green credentials may vary.
The most common is Pink fiberglass Batts which are by no means the worst from an environmental perspective but they aren't the best either. Fiberglass itself is chemically inert, but the glues and backing materials that provide structure to the batts can release dangerous fumes and there is some concern that minute particles of fiberglass can filter into living spaces, presenting a health risk. Rigid polystyrene panels, another popular choice, are made from petrochemicals which are flammable and emit toxic fumes when burned.
Misconceptions about Cellulose:
1: Prone to mold and insects; Cellulose Fiber is treated with two non-irritant, non-toxic, safe to handle allergy free agents; Borax and Boric acid which make it vermin resistant.
2: Fire retardant chemicals disappear in 5 years; The most exhaustive study and technical literature review concluded it would take 300 years to do so and only under continuous harsh conditions of 100% relative humidity and 70 degrees Celsius.

The History of Spray Foam Insulation
Movement of air in and out of a home can be a leading cause of escalated energy bills. Air can enter your house through holes, cracks and crevices. You can stop unconditioned air from entering your home and indoor conditioned air from escaping outside by adding an advanced insulation system to achieve optimal building performance.

Insulation is rated by number denoting how much of a thermal barrier each type of insulation provides. The farther north one goes the higher insulation number needed. Cold weather states, such as the Atlantic north-east, mountain states, and northern Mid-west require an R-49 rating. Warm weather states in the middle latitudes call for R-40; Southern and Gulf States would require R-38.
These guidelines offer the answer to the question, "how much insulation is enough?"
Adequate home insulation is the best way to keep a home comfortable while saving energy costs. With just a ruler, any homeowner can determine if they are meeting their insulation needs. With many options available to increase the insulation in an attic, no homeowner has to needlessly suffer through a cold winter, hot summer, or high utility bills.
