Insulation levels are specified using the R value. The R value is a measure of the insulation's ability to withstand heat flow. The higher the R value, the better the thermal performance of the insulation. The recommended level for most attics is to insulate them to R-38 or approximately 10 to 14 inches, depending the type of insulation.
How old your house is If your house is more than 10 years old, you probably need more insulation. There are many ways to modernize a house with fiberglass and mineral wool insulation. This map shows the recommended thermal insulation levels for various climate zones, as recommended by the U.S. Department of Energy (DOE).
U.S. Government and the International Energy Conservation Code (IECC)). The IECC is the model building code for the United States. The recommended R-value level in your home should be between 38 and 45 for a home with adequate insulation.
It depends on whether it faces the south side (sunny side) or the north (not so sunny side). For example, if you measured fiberglass insulation to a depth of 9 inches, the current R value of your attic insulation would be an R-26 and, to comply with the R-38 code, you would need a minimum of 3.5 mm of additional insulation throughout the building. If you want to reach an R38 (12.75 deep) and you have an R26 (9 deep), you need to add 3.75 additional insulation to your attic.

The best way to determine if you have enough insulation is to inspect the entire attic. Determining the right amount of attic insulation is crucial to maintaining a comfortable and energy efficient home. However, if you're looking to maximize efficiency, installing spray foam insulation in your attic is a great option. Two factors that contribute to the current thickness of your home's attic insulation are age and location.
Having the right amount of insulation in the attic can help you maintain a comfortable temperature throughout the house and save money on your energy bills*, in addition to preventing serious problems, such as ice build-up in winter. Whether it's hot or cold outside, attic insulation levels can dramatically affect energy consumption and the overall comfort of your household. Some of the attic insulation options can be installed as a DIY project, while others require a professional contractor. We wanted to share a quick resource that can help you determine your current level of attic insulation and an approximate R value for your current depth.
When adding additional insulation to your existing insulation, some experts recommend that you use the same type of insulation currently found in your attic. A warm loft is one in which it is insulated immediately under the roof, which means that the attic space is also warm. Here's a breakdown of attic insulation thickness, in terms of material, R-value, and what it can ultimately achieve.
