National Glass & Metal Company

What National Glass & Metal Company does

National Glass & Metal Company (NGM) is a privately held contract glazing firm founded in 1971 and headquartered in a 100,000 sq ft facility in Horsham, Pennsylvania. The company designs, fabricates, and installs custom architectural glass and metal systems for healthcare facilities (Children's Hospital of Philadelphia), higher education campuses (Princeton, Villanova), luxury retail storefronts (Coach, Gucci, Michael Kors, Tiffany & Co.), and government and commercial projects across the Mid-Atlantic and, via a dedicated retail facade division, nationally and internationally.

The company's core technical offering is the proprietary Lupton Architectural Products line, which includes storefronts, curtain walls, window walls, entrance systems, and specialty systems such as the Lupton PW-300 Hurricane Resistant Curtain Wall. These products are supported by an in-house engineering team, a library of thousands of custom aluminum extrusion dies, and full fabrication and assembly capabilities within the Horsham facility. NGM also deploys performance simulation and rendering software in the design-assist process, although the company's competitive differentiation rests on physical fabrication, tooling, and union installation craft rather than software IP.

Revenue is generated through project-based contracts—design-build, design-assist, and lump sum—awarded by architects, general contractors, and end clients, with separate go-to-market motions for Mid-Atlantic commercial work and national luxury retail rollouts. Pricing is driven by specification, custom engineering content, and project scope rather than recurring subscriptions, making revenue episodic and tied to the non-residential construction cycle in the Northeast.
