NettetFresh snow is an excellent insulator. Ten inches of fresh snow with a density of 0.07 inches, seven percent water, is approximately equal to a six-inch-layer of fiberglass insulation with an insulation R-value of R-18. Practically every location in the United States has seen snowfall. Even most portions of southern Florida have seen a few … NettetNote, for the ground snow regions considered, ranging from 10 psf (e.g., Nashville, TN) to 50 psf (e.g., Minneapolis MN), an R roof = 50 roof provides enough insulation that it behaves like an unheated structure. Also, for a location with (P g) 50 = 10 psf, (such as Nashville) a roof R-value of 20 or more provides enough roof insulation that it …
