Over Fifty Years of Manufacturing and Innovation

Eugene Lang

Eugene Lang in 1953

What do Thomas Edison, Buddy Holly, and Eugene Lang have in common? Each of them propelled a home business into a hugely successful venture.

Lang Exterior opened for business in 1953 in a garage on Chicago's southwest side with a single product: aluminum storm windows. Eugene Lang was the founder, the manufacturer, the salesman and the installer.

Lang built up the company and in 1968 acquired three 10-ton presses, two 5-ton presses, and all the dies necessary to expand into the prime replacement window market. Lang later developed a process to manufacture a wood-grain version of the solid white window-an idea he got from wood-grain shelf paper. He purchased a wrapping machine to affix the new finish to the vinyl profiles. But after 9 months of working until midnight 6 days a week, he told his son Darb, "It can't be done." The solution came to him the very next morning. That idea was the start of the Lang Exterior Top Coat® line of woodgrain finishes.
