It seemed that green products took center stage and solar applications provided the spotlight as more than 9,000 industry professionals converged on the Las Vegas Convention Center Feb. 21-23 for the International Roofing Expo. There were 442 exhibiting companies and 1,060 booths in 106,000 net square feet of space in the exhibit hall. At press time, final verified attendance numbers were not available, but preliminary numbers indicate that attendance was flat from last year’s record-breaking number of 9,020.
