Data is based on center of glass performance of representative factory production samples. Actual
values may vary due to the production process and manufacturing tolerances. All tabulated data
is based on NFRC methodology using the LBNL Window 6.3 software. Variations from previously
published data are due to minor changes in the LBNL Window 6.3 software versus Version 5.2.
Transmittance and Reflectance values based on spectrophotometric measurements and energy
distribution of solar radiation.
U-value is the overall coefficient of heat transmittance or heat flow measured in BTU/hr. • ft2 • °F.
Lower U-values indicate better insulating performance.
European U-Value is the overall coefficient of heat transmittance or heat flow measured in Watts/m2 •
°C, and is calculated using WinDat WIS version 3.0.1 software.

Shading Coefficient is the ratio of the total amount of solar energy that passes through a glass
relative to 1/8-inch (3.0mm) thick clear glass under the same design conditions. It includes both solar
energy transmitted directly plus any absorbed solar energy re-radiated and convected. Lower shading
coefficient values indicate better performance in reducing solar heat gain.
Solar Heat Gain Coefficient (SHGC) represents the solar heat gain through the glass relative to the
incident solar radiation. It is equal to 86% of the shading coefficient.
Light to Solar Gain (LSG) ratio is the ratio of visible light transmittance to solar heat gain coefficient.
Important glass design considerations and comprehensive technical information, including performance, thermal stress and wind load tools for all PPG
glasses are available at www.ppgideascapes.com/glasstechnical. Monolithic Glass Data can also be found at www.ppgideascapes.com/glasstechnical
