NOTE: Data published is for comparison purposes only and is accurate as of January 1, 2009. Performance data is for overall window/door units and not glass only. Data presented is based on DS annealed glass (tempered for patio doors) without grids. Other options may affect performance values. Please contact your Authorized AMSCO Dealer for actual values of units. U-Value measures how well the window prevents heat from escaping the home. The lower the number the better the window is at preventing heat transfer. Solar Heat Gain Coefficient (SHGC) measures how well a window blocks heat from the sun. The lower the number the better the window is at blocking the sun's heat. Visible Transmittance (VT) measures the amount of visible light coming through the window. The higher the number the better the window is at allowing light in. All values are certified through AAMA or NFRC.
