With today’s rising cost of energy and increasing code requirements, it only makes “cents” to insulate with the best material available. Spray foam insulation is the highest R-value per inch of thickness of any insulating material available. It also provides an air and moisture barrier, as well as a Class II vapor retarder, in one step. All these elements are required per the new codes. Installing all these in one step ultimately saves money.
Spray foams are non-toxic, sprayed-in-place insulation solutions. They offer added value because they can act as an air and moisture barrier solution that windproofs and seals wall, floor, and ceiling cavities. They prevent air movement (including spaces around electrical outlets and light fixtures, at baseboards and where walls meet windows and doors). This means that unconditioned air cannot seep in from the outside, which can bring with it moisture, insects, mold spores, pollen, dust, or other environmental pollution.

Spray foam, through its air-sealing ability, allows the homeowner, for the first time, to truly control his indoor air quality. Take into account the proven, increased performance of sprayfoam, and you save more money and energy. The majority of heat loss — 40 percent to 50 percent — is attributed to air infiltration. Stop this and you save 40 percent to 50 percent of your energy dollar.

That is what sprayfoam can do for you. If new construction is your goal, plan your work and work your plan. If you plan your insulation system in advance, you may save on other construction costs such as dimensional framing, windows, doors, venting, and HVAC systems.
Sprayfoam can make an old farmhouse perform like new again. It is the only way to get adequate R-value in the old-style two-by-four walls. The old framing was never perfectly spaced, but the sprayfoam will always fit — perfectly.

I spray over 100 rock and concrete basements and crawlspaces every year. Seventy percent of my customers report payoff of one season with the energy savings; the other 30 percent report payoff in the second year. I have never had a customer say it took longer than two seasons to pay off their investment. Where else can you get that kind of return on investment?
Lastly, but most importantly have your foam installed by a professional. They are experienced, have the proper equipment, training and safety gear to get the job done. Often times the pro is less expensive than the do it yourself kits as well. Feel free to call one. Those that will take the time to answer all your questions and concerns will also take the time to do the job properly.

There have been plenty of independent sources of information about spray foam, including Building Science Digests and the U.S. Department of Energy’s Oak Ridge National Laboratories. You can also find more valuable information about spray foam at
