Where is the SageGlass coating?
In the majority of applications, it is on surface two (the inside surface of the exterior lite). In this location, the SageGlass coating blocks solar heat before it ever gets inside the building, which means there is significantly less heat that needs to be removed by the HVAC system. By contrast, shades and blinds do not block heat from entering buildings. A building occupant might not feel heat directly on him or her if the shades are drawn, but the heat still gets in and must be removed by air conditioning.
