About Us

Glass Projects Resource, Inc. (GPR) was founded in 2005 by Vito John Germinario and Khalil Gabriel Rouhana with a clear vision: to deliver high-quality, innovative glazing solutions for complex building projects. Since then, GPR has grown into a premier glass and glazing subcontractor serving Washington, DC and the greater metropolitan area.

Headquartered in Sterling, Virginia, with a full-scale manufacturing facility in Berryville, Virginia, GPR offers a fully integrated approach to building enclosure systems. From design and engineering to fabrication, factory glazing, and field installation, every phase of a project is executed with precision and attention to detail.

Over the years, GPR has built a diverse portfolio spanning both exterior and interior glazing applications. While the company is well known for its united curtain wall systems, its expertise extends to specialized solutions such as blast and ballistic resistant glazing, exterior renovations, tenant fit-outs, and architecturally distinctive structures including glass bridges, train enclosures, rainscreens, and breezeways.

At its core, GPR is driven by a commitment to quality, safety, and reliability. The company partners with owners, developers, and general contractors to deliver projects on time and to the highest standards, regardless of size or complexity.

By continuously investing in advanced testing, modeling, equipment, and the latest building envelope technologies, GPR remains at the forefront of the industry, delivering performance-driven solutions that meet the evolving demands of modern construction.
