U-factor synonyms, U-factor pronunciation, U-factor translation, English dictionary definition of U-factor. n. A measure of the ability of a material to allow the flow of heat from its warmer surface through the material to its colder surface, determined as the A U-factor rating generally refers to the entire window assembly including the glazing, the frame as well as the spacer. The spacer is a part of the window that separates the glazing panels and this often results in the U-factor level dropping a bit.

U-factor / U-value - Range between .20 to 1.20; The lower the U-factor, the better the window is at keeping heat inside, this is desirable in colder climates like the Northeast; A higher U-factor allows heat to escape. This is desirable in very hot and sunny locations to avoid the greenhouse effect inside a home. U-factor and U-value are interchangeable terms referring to a measure of the heat gain or loss through glass due to the difference between indoor and outdoor air temperatures. U-factor or U-value is also referred to as the overall coefficient of heat transfer. A lower U … U-factor – Overall Heat Transfer Coefficient.

The spacer is a part of the window that separates the glazing panels and this often results in the U-factor level dropping a bit. The U-factor is defined by an expression analogous to Newton’s law of cooling: The overall heat transfer coefficient, U, is related to the total thermal resistance and depends on the geometry of the problem.

The U-Value or U-Factor measures how much heat a window, including the frame, glass, and insulating materials, allows out of the house, which is also known as its thermal transmittance. U-factor / U-value - Range between.20 to 1.20 U-factor is used to measure the insulation properties of windows but is not to be confused with r-value. The u-factor system, also known as u-value, was created by the National Fenestration Rating Council (NFRC).

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. U-factor 0.060 0.054 0.045 Effective R of wall 17 19 22 U-factor Comparison The R20+5ci wall is 15% more efficient than the R-25 wall. This is because the R-5ci creates a thermal break at the stud and header locations. According to the U-factor compliance table, the R20+5ci will work in any climate zone for thermal performance. R-value measures resistance to heat flow; U-factor is the mathematical inverse (1 divided by R-value gives you U-factor), and measures the rate of that heat flow. In a cold climate a good U-factor for a window is between 0.17 and 0.39.

U-Factor is especially important during the winter months and can make a big difference in heating costs. An assembly with a U-factor equal to or less than that specified in Table R402.1.4 shall be an alternative to the R -value in Table R402.1.2 U-Factor is a measure of thermal transmittance through conduction, convection, and radiation. It’s the inverse of the R-value commonly used for insulation. The lower the U-Factor, the better for thermal performance. THE U FACTOR SALON AND BOUTIQUE 6491 Winchester Rd, Suite143 Memphis, Tennessee 38115 +1 901-827-7778 theufactorinc@yahoo.com A window's U-Factor indicates the amount of heat energy that can pass through the window.

The lower the U-factor, the greater a window’s resistance to heat flow and the better its insulating properties. The nationally recognized rating method by the National Fenestration Rating Council (NFRC) is for the whole window, including glazing, frame and spacers. U-factor is used to measure the insulation properties of windows but is not to be confused with r-value.
