Optimal Low-E Coating Placment for Double- and Triple-Glazed IGUs

Achieving optimal performance of solar control low-e glass and passive low-e glass requires proper placement of low-e coatings on the glass surfaces of an insulating glass unit (IGU). Placement considerations vary depending on whether the glass is solar control low-e glass or passive low-e glass, and whether the IGU is double- or triple-glazed.
