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.
approximately 12 inches thick
Thereof, What is the thickness of R 38 insulation?
approximately 12 inches thick
Also to know is, What is the thickness of r19 insulation? 6.25″
Subsequently, question is, What is the thickness of r11 insulation? Thickness (inches) R-Value Cost (cents/sq. ft.)

3 1/2 (high density) 15 34-40
6 to 6 1/4 19 27-34
Also, How many inches is r11 insulation?
If the insulation is rock wool, you can estimate that 4 inches is around R-11, 6 to 7 inches is R-19, 9 inches is R-26 and 10 or 11 inches is R-30. Finally, if your attic has cellulose fiber insulation, 3 inches is around R-11, 5 inches is R-19, 7 inches is around R-26 and 8 inches is R-30.
What is R 19 insulation used for?
Use R-19 or R-21 kraft-faced fiberglass insulation for two-by-six (2×6) walls. This combination ensures that the insulation is neither too loose nor too tightly packed within the walls. Two-by-four (2×4) stud walls with true 4-inch depth.
Is r11 good insulation?
R11 is for sound and should never be used for exterior walls. It can be, but you’re spending money with little benefit. R13 is standard 2×4 insulation. R13 is also considered a higher density batt, if you look and feel the 2 (r11 and r13), there is huge difference.
What is the thickness of insulation?
Standard fiberglass insulation batts or blankets provide an R-value of 2.2 to 3.8 per inch of thickness. Most manufacturers produce an R-13 batt that fits into a 2-by-4 wall cavity, which is typically 3.25 to 3.5 inches in total thickness.
What is the thickness of R 19 insulation?
6.25″
What is R 19 insulation?
A wall is R-19, a roof is R-30 — what does this mean? Essentially R-value is a measure of thermal resistance, or the ability to prevent the transfer of heat. … Newer, smarter standards are 2×6 walls (a larger cavity provides more room for a thicker thermal barrier) with R-19 insulation.
What is R value for floor insulation?
How do you determine the thickness of insulation?
Q/N = 80W/m. Pipe Dia is 12″ hence radius is 6″. Radius in meters : (6″ X 25.4)/1000 = 0.1524 meters. Extra margin must be taken on insulation thickness as sometimes conducting heat transfer through insulation may become higher than convective heat transfer due to air on outside wall of insulation.
How long is a roll of r11 insulation?
R-11 Kraft Faced Fiberglass Insulation Rolled Batt 23 in. x 94 in. (12-Rolls)
How does thickness affect insulation?
The effects of insulation thickness on heat transfer for thermal protection system. … The numerical calculation results show that structure temperature decreases as the insulation thickness increases as well as temperature difference increases, however, this effect weakens as the insulation thickness increased.
What is the thickness of R 30 insulation?
10-inches
What R value is 6 inches of insulation?
19.2
How much does r11 insulation cost?
The cost for batt and roll insulation starts at $0.12 to $0.16 per square foot for a three-and-a-half-inch barrier that provides a value of R-11. The cost of a single roll of reflective insulation varies according to its R-value.
