2022年10月5日 · R38 insulation is required in ceilings in hotter regions and floors in colder regions. The thinnest insulation layer achieving the R38 rating is with closed cell spray foam polyurethane (5.38-7.6") and the thickest insulation layer achieving the R38 rating is with loose-fill fiberglass (15.7").

2023年9月7日 · R38 insulation has an R-value of 38, which is a measure of its thermal resistance. Using R38 insulation can reduce thermal conductivity by 97 percent. The thickness of R38 insulation ranges from 5.38 inches to 15.7 inches, with closed-cell spray foam requiring the thinnest and blown-in fiberglass requiring the thickest.
