(That's between R-6 and R-2.5). Lower is better with U-factor--the opposite of R-value, when higher is better. U-factor is the inverse of the R-value and considers, as tmurray indicated, the thermal bridging of stud elements. For example, a wall with 3-1/2" metal studs at 16" o.c. with R-11 insulation has an effective R-value of 5.5 (0.18 U-factor) due to the thermal bridging of the metal studs. U-factor or U-value is also referred to as the overall coefficient of heat transfer.

The coefficient of heat transmission (air to air) through a building component or assembly, equal to the time rate of heat flow per unit area and unit temperature difference between the warm side and cold side air films (Btu/h*ft2*Degree F)[W/(m2*K)]. Dave R. Answer: Dave, This whole “U-Value” vs.


Heat loss through common building elements due to transmission, R-values and U-values - imperial and SI units. Oct 8, 2019 Both U-factor and K-values yield very small numbers, and smaller is better. For example, EPS foam has a k value of like .033 and wood studs  The R-value is the resistance a material has to the flow of heat.

One BTU is the amount of heat needed to raise the temperature of one pound of water by one degree Fahrenheit. Thermal conductivity (kfactor) is the measureof a material’s - ability to transfer heat. U-value is generally used to rate doors and windows. A good U-value is a low number because it is a rating of how much heat energy is lost or gained; the lower the U-Value, the more energy efficient the unit is.

To determine the U-Value, you will divide 1 by R (U=1/R) and to find R-value, you will divide 1 by U (R=1/U). R-values are additive for layers of materials, and the higher the R-value the better the performance. The U-factor or U-value is the overall heat transfer coefficient that describes how well a building element conducts heat or the rate of transfer of heat (in watts) through one square metre of a structure divided by the difference in temperature across the structure. What is U-factor? R-value to U-value Conversion Calculator provides R & U values. U-value of a window tells you how resistant it is to conductive heat transfer, the lower the number the better. R-value is the insulative value to resist heat flow, the higher the number the better.
