What is R 38 attic insulation?
R-Value is a measure of insulation’s ability to resist heat flow. The higher the R-Value, the better the thermal performance of the insulation. The recommended level for most attics is to insulate to R-38 or about 10 to 14 inches, depending on insulation type.Click to see full answer. Thereof, how many inches of insulation is…

Thereof, how many inches of insulation is r38?An R-38 fiberglass batt should be approximately 12 inches thick, while the thickness of cellulose insulation of a finished, fitted product will larger.Additionally, what is R 38 insulation used for? R-38C EcoTouch® Thermal Batt insulation is intended to be friction- fit between wood rafters. In applications with irregular spaced rafters, cut the batts approximately ½ ” wider than the space and friction fit them in place. Tightly abut batts to prevent thermal leaks. Beside this, what is the difference between r30 and r38 insulation? 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. This means you could use R38 insulation, and then add another layer of R13, for a total of R51….Is R 19 insulation Good for attic?Most homes only have R19 in attics. To give you an idea that’s only 5 1/2 inches of insulation. So by adding another R19 “5 1/2 inches will give you an R38 value. And that’s a good number to live with.
