Owens Corning

A maker of asphalt shingles, fiberglass and foam insulation, and doors sold through distributors and home centers across North America, Europe, and Latin America. Founded in 1938 as a joint venture of glassmakers Owens-Illinois and Corning Glass Works, it takes its name from the two. Its pink insulation, tinted since the 1950s, made it the first US company to trademark a single color—PINK®—in 1987, and the Pink Panther has been its mascot since 1980.
