Edgemont Thermal Testing Footnotes

1 Windows tested per NFRC 100. Data applies to double-pane insulated glass units using a double-strength glass with a 1/2″ airspace.

Data applies to: *Edgemont double-pane insulated glass units using double-strength glass with 1/2″ air space.

2 Tested using GED’s Intercept® ULTRA low-conductance warm-edge spacer system. Calculations provided by Lawrence Berkeley Laboratory Window 7.4 and Optics5 software based on a 3/4″ IG unit for Edgemont windows.

3 Daylight Transmittance measures the performance of the glass only.

4 International Standards Organization Damage Weighted Transmission Rating (Tdw-ISO) calculations performed by Lawrence Berkeley Laboratory 7.4 Windows software and are weighted using the recommended International Commission on Illumination (CIE) standards.

5 Solar Heat Gain Coefficient (SHGC) tested in accordance with NFRC 200. This value varies by style, glazing system, and grids.

6 Condensation Resistance is tested in accordance with NFRC 500.
