What is the minimum R-value insulation required for supply ducts in attics?

The correct answer is: 8

The minimum R-value insulation required for supply ducts in attics should be at least 8. This R-value is crucial for maintaining energy efficiency in a building, as it helps to prevent heat loss in colder months and heat gain in warmer months. Proper insulation of ductwork is essential, especially in attics, where temperature fluctuations can significantly affect the air conditioning and heating system's efficiency. Effective insulation minimizes the energy needed to cool or heat the air transported through the ducts, leading to lower energy bills and a more comfortable living environment. While lower R-values may provide some level of insulation, they do not meet the standard required to ensure optimal energy efficiency and indoor comfort. Therefore, it's essential for contractors and builders in West Virginia to adhere to this insulation requirement to help promote sustainability and efficiency in construction practices.
