A Piece of Glass Thinner Than a Credit Card Could Solve America’s $25 Billion Energy Problem

Sheets of glass thinner than a credit card can be bigger than a queen-size mattress. This ultra-thin glass exists because of manufacturing and chemistry breakthroughs that made possible the light, strong, scratch-resistant screens on smartphones, tablets, and watches.

The Energy Department estimates that U.S. households each waste $200 to $400 a year on energy bills due to drafts, leaks, and inefficiencies, for a total of at least $25 billion a year. A new kind of window incorporating ultra-thin glass and advanced coatings could save American households billions of dollars in wasted energy each year.

These next-generation windows allow expansive views of the outdoors while making homes quieter, more comfortable, and able to survive even the most violent weather. The technology represents a fundamental shift in how windows are designed and manufactured.

Companies like NxLite are at the forefront of this revolution, developing proprietary energy-control coatings that can be applied to ultra-thin glass substrates. The result is windows that dramatically reduce heat transfer while maintaining exceptional optical clarity and light transmission.
