Crown Operations of Sun Prairie sold to California firm (

Crown Operations International, a Sun Prairie company involved in making energy-efficient window glass, has been purchased by Southwall Technologies of Palo Alto, Calif., for $3.3 million.

Crown, at 347 Business Park Drive in the Sun Prairie Business Park, was founded in 1988 and has 14 employees. Privately owned by founder Marshall Krone, the sale was effective Monday.

“It’s business as usual; the plant didn’t skip a beat,” said Crown president Curtis Liposcak.

Crown applies energy-saving films to a plastic layer that can then be sandwiched between two sheets of glass, creating windows that reflect heat and block ultraviolet rays.

Liposcak said the plant will stay open, and all the workers will keep their jobs. “A lot of the glass lamination that occurs in North America is east of the Mississippi River,” he said. “There’s a good likelihood that we could even expand our head count in the coming quarters.”

Southwall, founded in 1979, makes films and energy-saving glass for homes, commercial buildings and vehicles and has about 160 employees worldwide. Its shares are publicly traded on the over-the-counter bulletin board.
