Note: Glass COG u-factor is useful in designing and evaluating the glazing performance, however it is not enough for aluminum side of the business. When you are selling for a system (glass+alum), you will need to provide the weighted average U-factor. This method calculates the U-factor by averaging the U-factors of each component of the window system, weighted by their respective areas. This provides a more accurate measure of the overall thermal performance of the window, as it accounts for the fact that the framing and edge effects can significantly impact the U-factor.
