Currently, the industry offers low-E on both the #2 surface and the #3 surface. On which surface would you recommend applying the coating to achieve the best solar performance?
Most commercial or residential buildings in the U. S. are glazed with the low-E coating on the #2 surface for the maximum benefit in reducing heat gain to the interior of a structure. Reducing solar heat gain in the summer is more important for commercial buildings than increasing solar gain in the winter because the cost to air-condition a building is much higher than its heating cost. Low-E on the #2 surface reduces solar heat gain to the building’s interior. However, low-E is often used on the #3 surface when a tinted or coated outboard lite is used to provide even greater energy savings.
