Kinestral’s Halio Smart-Tinting Glass Passes ASTM E2141 Durability Testing

Kinestral Technologies Inc.’s Halio smart-tinting glass product has passed the U.S. Department of Energy’s National Renewable Energy Laboratories (NREL) testing procedures according to the ASTM E2141-06 test methodology required to meet the ASTM E2953 standard for electrochromic product durability. According to the company, it’s the only next-generation electrochromic technology to meet this standard.

During the NREL testing, Halio windows were subjected to 50,000 switching cycles over a period of six months at temperatures averaging 185°F (85°C). The extreme conditions had negligible impact on product quality and switching performance, according to the company. Halio’s visible light transmission was virtually unchanged in the clear and tinted states, and Halio still looked like traditional glass in its clear state and still tinted to neutral gray in its darkest state, according to the company.

“To achieve Halio’s performance, our scientists and engineers invented new materials and device physics that didn’t exist when electrochromic products began to enter the market 20 years ago,” says Howard Turner, co-founder and chief technology officer of Kinestral. “Manufacturing was also a prime consideration as we developed Halio to make sure we avoided the production issues faced by first-generation producers…”

Halio smart-tinting glass is available exclusively through Halio North America and Halio International, joint venture companies formed by Kinestral and AGC Inc.

“We partnered with Kinestral to bring to market a compelling occupant experience,” says Marc Van Den Neste, chief technology officer of AGC’s Building and Industrial Glass Company. “This ASTM durability certification confirms Halio’s quality, and that it’s the right smart-tinting glass solution for our customers.”
