Although the U.S. Department of Energy rates R-13 insulation as "good" for use in walls in southern areas of the country, it rates R-19 insulation higher, designating it as "great." That is because R-19 insulation provides more thermal insulation than R-13 does.
Which is better R13 or R19 insulation?
Inside your home, the warmer air is higher pressure air, and wants to move, or transfer to lower pressure, cooler air outside. Insulation in your walls and ceilings slows down this heat transfer. ... So R19 is better insulation than R13, and R30 is better than R19. The larger the R value, the better the insulation value.Dec 28, 2013
Is R-13 or R 15 better?
Is R15 better than R13? Answer: There isn't much difference between R13 and R15. However, higher R values offer higher performance. Therefore, in the case of efficiency, R15 is better than R13.Apr 8, 2021

Is R13 insulation good for walls?
Although the U.S. Department of Energy rates R-13 insulation as "good" for use in walls in southern areas of the country, it rates R-19 insulation higher, designating it as "great." That is because R-19 insulation provides more thermal insulation than R-13 does.
What's better R13 or R19?
There is a direct relationship between the amount of insulation and the amount of heat transfer. The bigger the R value, the better the insulation is at slowing down the heat transfer. So R19 is better insulation than R13, and R30 is better than R19. The larger the R value, the better the insulation value.Dec 28, 2013
What is the best R-value for insulation?
Typical recommendations for exterior walls are R-13 to R-23, while R-30, R-38 and R-49 are common for ceilings and attic spaces. See the Department of Energy's (DOE) ranges for recommended levels of insulation below.
