2019 Top Glass Fabricators | Standout Partners

McCormick & Co.’s new global headquarters in Baltimore

McCormick & Co.’s new global headquarters in Baltimore features 85,000 square feet of glass, with insulating glass units fabricated by J.E. Berkowitz. Studios Architecture stripped an existing utilitarian building to its foundation. But, installing a modern glass façade on the older building proved a challenge, especially fitting a new curtain wall system onto an existing structure, says Zubair Aabed, project coordinator for TSI Corp., the project’s glazing contractor. Troubleshooting required close collaboration between the structuring engineer and design team to adapt the anchoring system, he says. J.E. Berkowitz fabricated one-inch Winduo insulating glass units, featuring Guardian Glass’ triple-silver, low-emissivity SunGuard SNX 51/23 glass and SNX 62/27 glass coatings. The glass specification enabled the design team to maximize natural daylighting, reduce unwanted solar heat gain and match desired aesthetics, say company officials. Sunshades were provided by Clover Architectural Products. The general contractor was Gilbane Building Co. Photo courtesy of McCormick & Co.

The Top Glass Fabricators List ranks fabricator companies by gross sales. However, the editorial staff at Glass Magazine recognizes that there are many qualities that can make a company "great" beyond sales revenue. To showcase these qualities, Glass Magazine asked the contract glazing partners of glass fabricators, as part of the Top 50 Glaziers survey, to identify outstanding glass fabricators. Glass Magazine compiled the results in the inaugural Top Glass Fabricators Partners' List.
