Why an insulated attic is a good attic

As homeowners address energy efficiency around their homes, they may want to put attics at the top of their list. Because heat naturally rises during the winter and also infiltrates the roof during the summer, a roof with insufficient insulation can be energy inefficient. Many experts attest that upgrading attic insulation is a practical and cost-effective home improvement.

A desire to reduce energy bills is a primary motivator when installing attic insulation. Data from the U.S. Environmental Protection Agency's ENERGY STAR® program says homeowners can save an average of 15% on heating and cooling costs, or roughly 11% on their total energy bills, by air sealing and insulating attics and crawl spaces. Standalone attic insulation projects frequently achieve high rates of return.

Beyond financial matters, attic insulation also creates a more comfortable and stable indoor climate. Attic insulation will buffer the interior from extreme temperature swings. This can help preserve the integrity of the home. In cold climates, attic insulation will limit the occurrence of ice dams, which form at the eaves when heat inside living spaces escapes to the roof. Ice dams can cause water to back up under shingles and even tear away gutters.

The U.S. Department of Energy indicates residential and commercial buildings combined account for 40% of the nation's total energy consumption. By utilizing attic insulation and creating a proper thermal barrier, homes can draw less power from regional grids and burn less fuel locally.

Attic insulation may not be as glamorous as a room remodel, but it is an important component of a safe, comfortable and energy-efficient home.
