FORTUNE — View, a maker of¬†electronically-tinting glass for commercial buildings, earlier this month announced that it had raised $100 million in new venture capital and debt funding from Madrone Capital Partners.

Now Fortune has learned that the round was structured as an extension to the company’s $60 million Series E round, which was led last summer by Corning Inc. (GLW). That means the same pre-money valuation, which our source says was $600 million.

The Milpitas, Calif.-based company was founded in 2006 as Soladigm, and prior to the Series E round had raised around $115 million in VC funding from Khosla Ventures, Sigma Partners, DBL Investors, GE Energy Financial Services, NanoDimension, Navitas Capital and The Westly Group.
