In a home located in Zone 2, what is the minimum R-value for a ceiling as stated by the DOE?

The minimum R-value for ceiling insulation in a home located in Zone 2, according to the Department of Energy (DOE) standards, is set at 38. This value is determined based on factors such as climate, energy efficiency goals, and the specific heating and cooling needs of the region.

Zone 2 generally includes areas that experience moderate temperatures, which means adequate insulation is necessary to maintain energy efficiency and comfort. An R-value of 38 reflects a balance between energy savings and practical insulation levels needed for homes in this climate zone. Higher R-values may provide more insulation, but the DOE establishes minimum values to ensure homes are built or retrofitted to meet energy efficiency standards without being excessively rigorous for the climate.
