H.B. Fuller Ventures, the corporate venture fund of H.B. Fuller Co., has invested in SAGE Electrochromics, a manufacturer and developer of electrochromic glass. SAGE's product enables users to electronically control the amount of light and heat that passes through glass, without altering transparency.

"This is a strategic investment for Fuller. We have complementary technology and share a similar customer base with SAGE. Our investment offers H.B. Fuller visibility and partnership opportunities with the leading company in this exciting new market," said Bob McGrath, managing director of H.B. Fuller Ventures.
