What is the minimum insulation rating for walls in manufactured homes?

The minimum insulation rating for walls in manufactured homes is R-11. This standard is in place to ensure that manufactured homes provide adequate thermal resistance, allowing for energy efficiency and comfort for the occupants. Having at least R-11 insulation helps to keep the interior temperature consistent, reducing the need for excessive heating or cooling, which is crucial for both energy savings and maintaining a comfortable living environment.

In contrast to R-11, the other options suggest higher insulation ratings, which are not necessarily the baseline requirement for walls in manufactured homes. While R-19, R-30, and R-15 could be used in specific construction scenarios or climates requiring enhanced insulation, R-11 represents the minimum threshold established to ensure that manufactured homes are built with an appropriate level of energy efficiency and comfort in mind.
