| |
| − | :::<b><i>Note:</i></b> The design temperature differential for thermal expansion and contraction is the difference between the hottest and coldest panel surface temperature. The differential temperature should be based on the temperature range during the anticipated life cycle of the system, not the temperature change during a single year. Studies by the Army Corps of Engineers recommend this range to be 160ºF to 240ºF or more depending on climate, insulation, materials, and surface color.
| |
