Name that company

I trace my roots back to Alex Manoogian’s screw products company that began making parts for the auto industry in Detroit in 1929. In 1954, Manoogian designed a revolutionary single-handle faucet that was a hit. Today I’m a leader in home improvement and construction products, with more than 20 companies under my roof and dozens of manufacturing facilities worldwide. My brands include Behr paints, Delta and Hansgrohe faucets and fixtures, KraftMaid and Merillat cabinets, Milgard windows and doors, Kichler decorative and outdoor lighting and Hot Spring spas. My market value recently topped $12 billion. Who am I? Last week’s trivia answer: Viacom
