Labels:bulletin board | daily | monitor | reckoner | sky | skyscraper OCR: Thermal Performance U-values Impact Annual Energy Costs Based on data obtained from the Efficient Windows Collaborative at www fficientwindows org, the aluminum and aluminum-clad wood window descriptions, U-values and Solar Heat Gain Coefficients (SHGC) for this analysis are shown in the next slide. The single-glazed aluminum window has clear glass The aluminum and wood windows with insulating glass both have the same type of low-E glass The only difference is in the frame so this analysis provides an accurate indication of what impact the frame plays in the overall energy performance of the window The site references many different window types with wide variety of frame and glass types The low-E glass 15 clear (no tint) and spectrally selective U-values and SHGCs are for the total window ...
