The R-value you need depends on where you live in Louisiana, your home’s design, and which areas need insulation. R-value measures how well insulation slows heat flow, keeping your home comfortable and energy-efficient.
Louisiana is split into two climate zones with these recommendations from the U.S. Department of Energy, based on the 2021 International Energy Consersation Code:
- South Louisiana (Zone 2): Attics need R-49 to R-60 (new insulation) or R-38 to R-49 (existing insulation). Floors should have R-13.
- North Louisiana (Zone 3): Similar attic needs, but floors should have R-19 for better protection.
Remember that factors like moisture, air leaks, and age can lower insulation performance over time. Proper installation and maintenance are crucial.
