The color PINK is one of the things I like best about Owens Corning brand insulation. Way back in 1956, before I was born, the company developed a process for a much better glass fiber. The improved product had almost no "shot," which was what they called the small bits of glass that were not made into fibers. The sales department wanted a way to distinguish the new fiber from the standard product and the folks at the factory in Newark, Ohio added a red dye to the binder sprayed on the insulation to help it spring back to its full thickness when installed. The red dye made the improved product PINK instead of yellow. I started doing commercials for insulation in 1980 and in 1987 Owens Corning received a trademark for the color PINK used with insulation, thus becoming the first company to trademark a color. Thanks for asking.
