While it won't come as a surprise to many, the numbers are in, indicating that 2010 was a difficult year for U.S. contract glazing firms. A large majority of the country's leading contract glaziers experienced sales losses between 2009 and 2010, according to Glass Magazine's Top 50 Glaziers survey. Sixty-five percent of the companies with confirmed 2009 and 2010 sales data—43 of the Top 50—experienced a decline in sales in 2010. Of companies reporting a sales loss, 57 percent saw sales drop more than 30 percent from the previous year, and 11 percent saw sales decrease more than 50 percent.

A third of companies reported a sales increase from 2009 to 2010. One company's sales remained the same. Those companies that did see gains saw modest ones, for the most part. Additionally, most of the companies that reported gains were regional or local glaziers. Of the companies ranked in the top 30, only four saw sales increase from 2009 to 2010.

About the list

The annual Top 50 rankings present what Glass Magazine editors believe to be the United States' 50 largest contract glazing firms, based on sales volumes. The glazing firms are ranked within eight sales categories.

The majority of the information included in the Top 50 comes directly from contract glazing firms; however, some companies request that we not include them or refuse to provide any information. We understand the sensitivity of releasing sales figures; however, we do not omit any firms simply because they ask. In cases where a company declines to provide information, we use independent sources, such as Dun & Bradstreet and Hoovers, to determine its ranking. The end result reflects the leading companies in the commercial glazing marketplace, at least from a sales perspective.

If your company belongs on the list, or you would like to update its information, please contact us. It is only with the cooperation of individual companies that Glass Magazine's Top 50 Glaziers rankings can be as accurate as possible. Questions or comments about this year's rankings, and requests to be included next year can be sent to kdevlin@glass.org.
