We don't mind telling you that Guardian is one of the world's largest manufacturers of float glass and fabricated glass products. You should also know that we manufacture and supply the automotive industry with a variety of exterior products. We've also become a significant player in the building materials distribution business and are a major manufacturer of fiberglass insulation. And somewhere along the line, we became one of the world's largest producer of mirrors. Headquartered in Auburn Hills, Michigan, the privately held Guardian group of companies employs 18,000 people worldwide (that's more than 25 countries on five continents) and we value them above all else. In fact, we are very proud of our management structure. It is specifically designed to avoid bureaucratic nonsense and allows the individual to flourish. It is an environment that thrives on the initiative of its people. And it works. Just ask any of our thousands of happy customers.
