AGC Group boosts its stake in smart-tinting glass developer Kinestral Technologies

The AGC Group has consolidated its stake in the Californian start-up Kinestral Technologies, developer of Halio™, the world's most responsive smart-tinting glass. This product is currently the most advanced solution for management of natural lighting levels thanks to glass that switches electrically from clear to dark.

GC Leads Kinestral Series C Financing Round

The AGC Group led the 65 million US dollars raised in the C-series equity funding round aimed at launching Halio into the global marketplace (planned for early 2018). In addition to the financial aspect of this strategic partnership, AGC and Kinestral are further pursuing their technological and commercial collaboration, which has led to the product being presented for the first time in Europe to a selected audience at the Bau fair1.

Great new prospects for the building industry

Halio is the first-ever solution which looks exactly like ordinary glass while being able to uniformly darken within three minutes, affording protection against the glare and heat of the sun and against prying eyes. "As part of a building management system (BMS), Halio ushers in the age of interactive window glass, connecting the building occupants to their environment while neutralising all the excessive aspects of the sun," declared Jean-François Heris, President of Building & Industrial Glass Company, AGC. Moreover, Halio is the key stepping stone into the new business paradigm of the “Connected” IoT2 building window.
