Green Living Technologies International

What Green Living Technologies International does

Green Living Technologies International (GLT) is a privately held US-based engineering and manufacturing company founded in 1999 that designs, produces, and supports commercial-scale living infrastructure, primarily green roofs, living walls, and vertical farms. The company is headquartered in Rochester, USA, with precision manufacturing facilities in Berlin, Toronto, and Chile, and has completed projects in 13 countries. Its core products are patented modular aluminum living wall systems and engineered green roof systems, both built around Class A fire-rated, non-combustible assemblies intended to function as permanent building infrastructure rather than decorative landscaping. Supporting products include stormwater infrastructure modules, native landscape systems, irrigation systems, elevated landscape systems, interior biophilic environments, and vertical farming systems, all unified under the company's Living Infrastructure Layer™ platform.

GLT's business model combines one-time hardware sales (living wall and green roof systems) with professional services such as feasibility studies, engineering, CAD details, specification development, and installation consulting, plus a recurring layer of long-term maintenance contracts delivered through its ProStaff™ certified installation and maintenance network. Pricing is custom and quote-based, with free preliminary budgeting and design support offered to project teams. The go-to-market is consultative enterprise field sales: GLT partners with architects, landscape architects, engineers, developers, and contractors from early design through construction, targeting AI and mission-critical data centers, healthcare campuses, higher education institutions, sports venues, commercial real estate, hospitality, and municipal projects. Named customers include MLB stadiums (Target Field, Citi Field, Marlins Park), Hotel Intercontinental, Hakkasan Dubai, Rolex, UR Medicine, Pacific Guardian Center, and Liberty Mutual, indicating a project-driven, logo-rich enterprise model rather than a high-volume SMB business.

The company is led by founder George Irwin, operates with 11–50 employees, and shows no disclosed funding rounds, M&A activity, or public-company signals. Its competitive positioning rests on patented aluminum system technology, Class A fire ratings required for mission-critical facilities, and a 25-year track record of commercial reference projects. Revenue, ownership structure, and management team composition beyond the founder are not publicly disclosed, representing notable data gaps for any prospective investor or acquirer.
