Insulation Requirement for Home Attics
Insulation is an important part of keeping the home warm in the winter, and cool in the summer. If you have a new home, you may need to add insulation. If your house is older, you may need to change the type of insulation you have or add more to the existing layers. All of this must be done to code. Doing it right the first time can save you money and time. Does this Spark an idea?

Adding to Existing Insulation
-
Have a qualified home energy auditor visit your home to determine where you have insulation, how much is there and what kind of insulation was used. An energy auditor will tell you what you need to do to get your house energy compliant and up to code if you are planning on installing new insulation. If you find out that you have vermiculite insulation, do not replace this on your own. This type of insulation contains asbestos, which is harmful to you health. Call a contractor to do it for you.
MEC/IECC
-
The Model Energy Code sets out criteria for energy conservation in residential and commercial buildings. It also sets forth guidelines for additions to existing buildings. The MEC sets forth guidelines for lighting, walls, floors and foundations. The MEC is a part of the International Energy Conservation Code, or IECC.

REScheck and COMcheck
-
The U.S. Department of energy provide two programs of self education called REScheck and COMcheck. These are training programs that provide clear and concise information on how to insulate the home according to energy requirements set for by the government. REScheck can be used for residential homes in states that have adopted MEC/IECC standards, while COMcheck can be used by states that have adopted IECC for commercial purposes.
Where to Insulate
-
According to the U.S. Department of Energy, the appropriate places to add insulation in a home are attic spaces, including access doors and knee walls (a short wall under three feet high), in ducts, cathedral ceilings, exterior walls, floors above garages without heat, and housing foundation.
R-Value
-
An R-value signifies the insulation's resistance to heat flow. Insulation blocks heat flow from exiting a house, as well as allowing heat to enter the house in areas where the insulation is placed. The higher the heat flow resistance, the lower your heating and cooling costs will be. You must install insulation according to the R-value requirement of your state. You can find out your local requirements by visiting the U.S. Department of Energy website or from your local building authority.
