One of the best ways to make an energy efficient home is to insulate your attic adequately.As heat rises,it will escape through an attic which is not insulated. At least 70% of heat energy can be saved if proper insulation is installed. While choosing the type of insulator,it is also important to note the R-factor of the material used. This factor indicates the ability of the insulating material to check the heat flow. It is a numerical gauge, which specifies the efficiency of the material in stopping convective heat transfer. The scale is from R 24 – R 39.Cellulose fiber and Fiberglass is usually used as insulation materials for the attic.They have an R-factor of approximately 3.5 per inch

The insulating material Cellulose is made up of newspaper material which has been pulverized and is then given a treatment of chemicals that are fire-retardant. As the material is finely powdered, it can be propelled easily into all the spaces in the attic, by means of a blower. This will make the area fully insulated. Normally companies that deal with these products will also loan the use of a blower in applying the insulation. Cellulose insulation also prevents the movement of air currents in the insulation and enables it to retain its R- value.
Fiberglass is also used as an insulating material and is made up of numerous strands of glass fibers which have been extruded. They are then made to form specific sized bats.These bats are also treated with a fire retardant chemical. Fiberglass bats are now available in poly bags which aid in encasing it and retain any loose glass fibers. This also helps in the installation and handling of fiberglass insulation. It is important to fit them properly to ensure that the right level of insulation is obtained.
Making your home energy efficient does not stop by just insulating your attic. Regular maintenance of the heating and cooling equipment is also necessary to provide for a total energy saving home.
