Attic insulation is a key factor for the energy efficiency of any home and the comfort level of its inhabitants. It is a thermal resistance layer that resists heat gain from the attic into the home in hot weather or heat loss out of the home in cold weather. Visit The Department of Energy for more information.

Think of attic insulation in terms of a pan placed on top of a hot stove. Quickly the pan would get very hot because the metal in the pan is a good conductor of heat. Insulation, however, is made out of fiber glass which is a poor heat conductor and contains tiny air pockets which trap heat and prevent it from circulating. In essence, attic insulation acts like a sponge absorbing heat and resisting heat gain into or heat loss out of the living area. When a sponge gets full it cannot absorb more water, which is why it is important to have sufficient levels of insulation.

Insulation effectiveness is measured by R-Values which range from R11 to R60. Higher insulation thickness in inches translates into higher R-Value and greater energy efficiency. The U.S. Department of Energy recommends an R-Value of R49. According to the International Energy Conservation Code, 55 percent of attics in existing U.S. homes are under insulated.
