Licensed to use the company's Intercept glass unit technology are MGM Industries, Hendersonville, Tenn.; Jannock Vinyl Group, Pittsburgh, Pa.; and Marshall Vinyl Windows, Corona, Calif.

According to Bradley P.

Intercept technology accounts for more than 40% of insulating glass unit production in North America, Boone said.

PPG has licensed more than 70 window and insulating glass unit manufacturers in six countries to use its Intercept insulating glass unit technology, which was introduced in 1992.
