Corning® Enlighten™ Glass​ has been engineered to bring energy performance, comfort, and beauty to built environments.

As a world leader in glass and ceramics for nearly 175 years, Corning is vital to the progress of material science innovations. From the development of the encasement for Thomas Edison’s lightbulb to cover glass on the latest smartphones and the fiber optic network that’s supporting your high-speed internet connection, Corning’s purposeful inventions place us at the center of the way the world interacts, works, learns, and lives. Our sustained investment in research, development, and invention means we’re always ready to solve the toughest challenges alongside our customers.

As a long-time innovator, Corning is always looking for synergies where our material science and process manufacturing expertise intersect with critical global macro trends such as high-performance buildings and sustainable construction. One of the latest areas where we are applying our glass science and manufacturing expertise is the architectural industry.

As one of the largest glass markets in the world, the architectural glass space is a natural fit for Corning, and we believe innovation in the windows industry is an important issue to work on. Nearly 25% of global energy production is used to heat and cool buildings. And, although windows represent a small percentage of the surface areas of these buildings, they represent nearly half the heat loss of a home or business. Corning has been working on a suite of solutions to improve thermal performance within the fenestration industry.

Corning® Enlighten™ Glass is an enabling technology for high-performance windows and doors that can significantly enhance the thermal performance, comfort, and beauty of built environments. As the interior pane of insulated glazing units (IGUs), it provides a lower incremental cost and lower-carbon path to improved energy efficient windows compared to traditional soda-lime glass.

Enlighten Glass has an inherently lower Coefficient of Thermal Expansion (CTE) than soda-lime glass due to its boro-aluminosilicate composition, which means that Enlighten Glass has lower thermal stress under temperature gradients, so it does not need to be heat strengthened. Heat strengthening is necessary with soda lime glass to prevent its inherently higher risk of thermal field failure with its high CTE.

Enlighten Glass is formed through Corning’s proprietary fusion draw process which has become the industry’s most efficient method for producing pristine, thin, stable flat glass. With the fusion draw process, the glass surfaces are not touched by a molten tin bath or rollers – enabling a pristine surface and reducing the chances of flaws within the glass – hence increasing its mechanical properties during post processing and final use.

Corning is working with customers around the world on the best ways to integrate its ultra-thin Enlighten Glass into next-generation IGU applications. One of these collaborations is with Regency Glass Ltd., who Corning is working with to launch next generation, advanced triple-glazed units in early 2026. This new product will help set a new industry standard for IGU products in the United Kingdom.

With Enlighten Glass, Corning is using the power of glass innovation to bring enhanced energy performance, comfort, and aesthetics into homes and businesses around the globe.
