Harmon

What Harmon does

Harmon Inc. is a specialty construction contractor that designs, engineers, fabricates, and installs custom unitized curtain wall systems for complex commercial building facades across North America. Founded in 1949 in Minneapolis and headquartered in Bloomington, MN, the company operates as a wholly-owned subsidiary of Apogee Enterprises, Inc. (NASDAQ: APOG) within Apogee's Architectural Services segment, employing more than 1,100 people across seven U.S. regions and Canada. Harmon is recognized by USGlass, Glass Magazine, and ENR as the #1 Largest Contract Glazier in North America.

The company's core offering is end-to-end curtain wall project delivery through four integrated service lines: preconstruction (system solutions, constructability review, scheduling, competitive cost analysis); engineering and design (structural/thermal analysis, BIM, shop drawings, fabrication models); manufacturing (in-house fabrication plus assemble-glaze operations at owned facilities in Dallas, Cincinnati, and Brampton, ON); and field operations (schedule-driven installation). Its proprietary product family includes the UCW8000 and SMU6000 unitized curtain wall systems plus the HYBRID-WALL system for hurricane impact and blast resistance applications. Project examples span commercial office (Salesforce Tower, 609 Main at Texas), healthcare (Rutgers Cancer Pavilion, Texas Medical Center), government (U.S. Coast Guard Headquarters), transportation (Denver Airport Westin), automotive (Toyota), and multifamily (561 Greenwich).

Revenue is generated primarily through project-based B2B contracts with quote-based, multi-year pricing tied to scope, complexity, and square footage. Customers — commercial developers, institutional owners, architectural firms, and general contractors — are reached through a regional enterprise field-sales model staffed by preconstruction managers across seven U.S. territories (West, Northeast, South Central, East) plus Canada. The company pursues no third-party reseller or marketplace channels; all work is won via direct relationships and competitive bidding. Harmon complements its core business with active exploration of automation through a 2025 partnership with Raise Robotics and Universal Robots A/S for robotic glass panel bracket installation.
