| 1 Most common combination; many other
combinations available. |
| 2 Approximate values by ASTM E-972. Light
transmission values over 30% not recommended for most applications. |
| 3 At 0° incident angle. Numbers for
various panels are calculated based on tests. |
| Shading Coefficient (SC) is equal to
1.15 times the Solar Heat Gain Coefficient (SHGC). |
| 4 For Design Day of August 21, Noon,
Horizontal, Lat. 40. Expressed as Btu/(h•ft2). DS glass would be 247. |
| 5 U-values determined by NFRC test method
(ASTM C-236, E-1423 and C-1199 at certified lab). |
| Expressed as Btu/(ft2•h•°F) for
aluminum grid / thermally broken grid, nominal 12" x 24". |
| Perimeter aluminum excluded. Test
temperature at 15 mph wind (6.7 m/s): 0°F (-18°C) cold side & 70°F (21°C)
warm side. |
| 6 Type A and SWC face sheets are similar
in light transmission and solar heat gain properties. |
| White High-Impact same as standard white. |
| 7 Estimated based on standard engineering
calculations. |
