National Enclosure Company

What National Enclosure Company does

National Enclosure Company (NEC) is a privately held specialty contractor and subsidiary of National Construction Enterprises, Inc. (NCE), focused on the design, fabrication, and installation of unitized curtainwall systems and advanced facade solutions for commercial and institutional buildings. The company operates primarily across the Midwest, Northeast, Mid-Atlantic, and Southeast regions of the United States, serving clients in higher education, healthcare, cultural, defense, financial services, and corporate office sectors. Notable customers include University of Michigan, Ohio State University, University of Pennsylvania, Capital One, General Dynamics, Goodyear, and Allegheny Health Network.

NEC's core product is its proprietary HVU Series unitized curtainwall system, a factory-assembled solution engineered for thermal performance, air and water infiltration resistance, and accelerated field erection. The company offers a portfolio of supporting services including Design Assist (a collaborative project delivery methodology used on nearly 100% of projects), Building Information Modeling (multi-level Revit-based modeling integrated with Autodesk BIM 360 Field for quality control documentation), Advanced Structures (AESS grid systems, tensegrity, structural glass, and composite materials), and Rainscreen Systems for weather intrusion control. The company operates a 40+ year old curtainwall specialty practice under the financial umbrella of its 60+ year old parent NCE, which provides large bonding capacities.

NEC operates a project-based B2B business model with custom pricing determined through the Design Assist process. The go-to-market relies on direct enterprise sales (led by dedicated personnel such as Bill Lincoln) targeting architects, construction managers, and building owners. Revenue is generated through one-time, multi-year contract awards for specific construction projects, with no standardized pricing tiers disclosed. The company has been recognized as a top-tier specialty contractor, ranked #38 in Glass Magazine's 2025 Top 50 Glaziers (up from #42 in 2022) and #18 in ENR's Top 600 Specialty Contractors in the Glazing and Curtain Wall category. The firm was founded in 1985 per company records (though firmographic data indicates 1957, likely reflecting NCE parent lineage) and is headquartered in Ypsilanti, Michigan, with a fabrication and assembly plant in Massillon, Ohio.
