What is the minimum R-value recommended for attic insulation in Texas?

The minimum R-value recommended for attic insulation in Texas is R-38. This value reflects the energy efficiency standards set to help reduce energy costs and improve comfort levels in homes. R-value measures thermal resistance, meaning that the higher the R-value, the better insulation can resist heat flow. In the context of the warmer climate commonly found in Texas, adequate insulation is vital for maintaining cooler indoor temperatures and reducing reliance on air conditioning, thereby saving energy and costs. While R-30 and R-20 are lower than the recommended value, R-50 is generally considered excessive for most residential applications in Texas, making R-38 the most appropriate choice for optimal energy efficiency in attics.
