At first glance you might not think about glass when you see the name “Berkshire Hathaway,” but the company, led by Warren Buffet, does in fact have a place in the industry. MiTek Industries, a Berkshire-Hathaway company, acquired Portland, Ore.-based Benson Industries last year was ranked #4 on Fortune magazine’s list of the “World’s Most Admired Companies.” Several other companies with ties to the architectural glass industry were also included in the issue, which is expected to hit newsstands later this month.

Two companies with ties to the glass industry were ranked in the top 50. These included Saint Paul, Minn.-based 3M at #23 with an overall score is 6.33 and DuPont at #43 with a score of 6.05.

Other industry-related companies to be scored but not ranked in the top 50 included:

  • Alcoa, with a score of 7.49;
  • Autodesk, with a score of 6.14
  • Bayer, with a score of 6.36;
  • Corning, with a score of 6.55;
  • Ingersoll-Rand, with a score of 6.85;
  • Johnson Controls, with a score of 6.62;

“The Most Admired list is the definitive report card on corporate reputations,” according to Fortune. Fortune began with about 1,400 companies, including the Fortune 1,000—ranked by revenue and non-U.S. companies in Fortune’s Global 500 database with revenue of $10 billion or more. The company then selected the 15 largest companies for each international industry and the 10 largest for each U.S. industry, analyzing 692 companies from 30 countries.
