FAQ
What Tax Credits are available?
What Tax Credits are available? Tax law is constantly changing. For the latest information visit http://www.energystar.gov or www.irs.gov.
Are there incentives available from my local utility company?
Utility companies, especially those generating power in coal-fired plants, are encouraged through various federal and state initiatives to support consumers and businesses seeking to implement energy conservation programs. Check your utility company’s website or call their local office to find out what incentives are available in your area.
What do I need to do to qualify for these incentives?
Each incentive program will outline their requirements. If you are depending on incentives, make sure you understand whether you qualify for them before beginning your work.
Where can I find information on other Energy Saving opportunities?
A good source for energy saving tips is the Energy Star program website from the US Government at www.energystar.gov.
How much more insulation should I install?
Each area of the country has different recommended R-values for insulation. Click on this map to find out the recommended R-values for your area and use our insulation calculator to see your potential savings.
How do I know the R-value of my current insulation?
Every product has a different R-value so make sure you read the packaging carefully.
As a rule of thumb, if you have six inches or less in the attic, it would be smart to add more insulation. Use this map to determine what total R-value is recommended for your area.
You can always add more insulation in the attic on top of the existing insulation to achieve even more energy savings and comfort. Use our insulation calculator to see how much you can save.
Do I have to take out the insulation that is already there?
Not necessarily. Adding more insulation has a cumulative impact on the overall R-value. In attics, If the insulation is damaged or improperly installed, in the case of batt products, it might make sense to replace it completely with blown-in cellulose insulation.
You can also add cellulose insulation on top of the existing insulation, improving the overall quality and R-value.
In walls, it is possible for contractors to install additional insulation so it compresses the existing material, completely filling the wall cavity with performance enhancing cellulose insulation.
How do I find a contractor?
Check your local Yellow Pages, or try a Google search. Your local utility company or natural resources council may have information as well. You can also contact a CIMA Producing Member and ask about installers in your area that use their products. Once you have identified potential contractors, use our guidelines on hiring a contractor here.
Which is the best insulation for the environment?
That’s easy – cellulose.
Cellulose insulation is made from at least 80% recycled paper, primarily newsprint, giving it the highest recycled content of any insulation product. Cellulose insulation also has the lowest embodied energy score of any major insulation. It takes less energy to produce and transport cellulose insulation, which means fewer emissions are released in manufacturing it. Fiberglass uses approximately 10 times more energy than cellulose insulation to produce and transport, while foam products, derived from petroleum, use even more. In addition, neither of these products is recyclable.3

Do I need a Vapor Retarder?
With cellulose insulation, a vapor barrier isn’t recommended except in cases of high humidity areas, such as pools and spas.
What is the best insulation to use in a cold climate?
Studies by Oak Ridge National Laboratory show that the performance of fiberglass insulation degrades dramatically when the difference between the internal and external temperature exceeds 30 degrees, while the performance of cellulose remains stable.
Refer to our chart for more information.
How much money can I save installing more insulation?
For a general idea on how much you could save on your utility bills by increasing your insulation use our savings calculator.
What does R-value mean?
R-value is a measure of resistance to heat flow through a given thickness of material. The higher the R-value, the greater the resistance. As explained in the section, “Why Insulate?”, resisting heat flow is the primary purpose of insulating, which in turn lowers energy costs. Click here to find the recommended R-values for your area.
Where can I get Cellulose insulation if I want to do it myself?
Cellulose insulation is available at most home improvement stores and lumberyards. Many stores also rent machines for installation, and can also help with any insulation questions you might have.
Do I need any Special Equipment?
Yes. You will need a blowing machine which can be rented or sometimes loaned from most home improvement stores or lumber yards. As with most home improvement projects, it is recommended that you wear protective gear such as a mask and goggles for minimum discomfort during the installation process.
