Aesthetic versatility is another prominent feature of IGU glass. With advancements in glass technology, manufacturers can produce IGUs in various styles, colors, and coatings to suit diverse architectural designs. Low-emissivity (Low-E) coatings, for example, are commonly applied to the surfaces of IGU glass to minimize radiant heat loss while still allowing natural light to enter a space. This innovation not only enhances the overall appearance of a building but also maximizes daylighting, thus improving occupants' mood and productivity.
