2020-01-05 The U-factor alternative (2015 IECC R402.1.4) is a very powerful and useful method, but I don’t see it get used much. I think it can be useful to use a chart like the one below to see building assembly alternatives by U-factor.

THERM will assign them correctly in most cases, but there are some situations where they will not be generated correctly automatically.

U-factor / U-value - Range between .20 to 1.20. 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.

Various performance ratings – like U-factor and Solar Heat Gain Coefficient – measure a product's effectiveness in insulating and blocking heat from the sun,

U factor

U-factor / U-value - Range between.20 to 1.20 In a nutshell, it’s a measurement of how energy efficient the window is. Energy Star defines U-factor as the measurement of the rate of heat transfer, with this rating telling consumers how well the window insulates. Ranging from 0.25 to 1.25, U-factor is measured in Btu/hr-ft2-oF.

U factor

Frame U-Factor includes heat transfer through surfaces perpendicular . to the glass plane.

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.

2004-03-01 · The U-factor is a measure of heat transmission, in this case through a concrete slab, either from the ground into the enclosed space or vice versa. It is expressed in BTUs per hour, per square foot, per degree Fahrenheit, referring to the temperature difference between the slab’s upper and lower surfaces.

The lower the U-factor of a window is, the better it will be as an insulator. How the U-factor plays a part in home insulation Knowing what R-value and U-values mean is key to following energy issues and to selecting products that best suit the climate zone you are building in. R-value is essentially a product's resistance to heat flow.
