Low-emissivity glass (Low-e glass) is characterized by which behavior?

• A. Laminated glass
• B. Frosted glass
• C. Low emissivity glass (Low-e glass)
• D. Ordinary glass

Answer: (C)

Low-emissivity glass is defined by its ability to limit heat transfer through a special coating. That coating dramatically reduces emissivity, meaning it reflects or blocks infrared (heat) radiation while still letting visible light pass. So you get daylight without as much radiant heat entering or escaping the space. In practice, this helps keep interiors cooler in hot tropical sun and can improve overall energy efficiency and comfort. Laminated glass, frosted glass, and ordinary glass don’t inherently change infrared emissivity, so they don’t share this heat-control behavior.
