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?
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. Certain low-E coatings are approved for #3 surface applications but require a tinted or coated outboard lite.
