Webb3 mars 2024 · Rather than finding insulation with an R-value of R38 per inch of thickness, you simply need to have enough inches of insulation to equal the recommended R-value. If your attic has, say, 12 inches of room for insulation, you’ll need to source insulation with an R-value from R3.2 to R5, equating to a total R-value of R38.4 to R60. Webb2 mars 2024 · Insulation is rated on a scale called an R-Value. When the R-value of a material is low, it conducts heat very easily. When a material’s R-value is high, it does not conduct heat well, making it a good insulator. The US Dept of Energy considers “High R-Value walls” to be R-40 or above for Zero Energy Ready.
