|According to The US Department of Energy: To get the biggest savings, the easiest place to add insulation is usually in the attic.
A quick way to see if you need more insulation is to look across your uncovered attic floor. If your insulation is level with or below the attic floor joists, you probably need to add more insulation.
The recommended insulation level for most attics is R-38 (or about 12–15 inches, depending on the insulation type).
More than any other time of year, you notice your home’s air leaks (drafts) in the winter. You may feel these drafts around windows and doors and think these leaks are your major source of wasted energy.
|In most homes, however, the most significant air leaks are hidden in the attic and basement. These are the leaks that significantly raise your energy bill and make your house uncomfortable.
In cold weather, warm air rises in your house. This heated air (that you paid to heat) is just wasted as it rises up into your attic and sucks cold air in all around your home—around windows, doors, and through holes into the basement.
The illustration below shows warm air leaving (red arrows) the house through the attic and cold air being pulled into the house (blue arrows).
