New Construction Glazing

Herzog Glass works with general contractors, developers, architects, and manufacturers to furnish and install commercial glazing systems for new construction projects. Our team supports the work from preconstruction and design coordination through shop drawings, submittals, procurement, fabrication, installation, testing, and closeout. Early involvement allows us to identify technical requirements, constructability concerns, scheduling constraints, and opportunities to improve the installation process.

Tenant Improvements and Renovations

We provide glazing for tenant improvements, occupied-building renovations, retail buildouts, office interiors, and other commercial upgrades. This work may include storefront entrances, interior glass fronts, conference rooms, glass doors, railings, mirrors, decorative glass, and modifications to existing exterior systems. Our project teams understand the scheduling, access, protection, and coordination requirements involved in working within existing and occupied buildings.

Commercial Glass Fabrication

Herzog Glass operates an approximately 30,000-square-foot fabrication facility supporting our commercial, residential, and service divisions. Our in-house capabilities include cutting, edging, drilling, painting, and preparing glass, aluminum, and related glazing components for installation.

LuxWall Vacuum-Insulated Glass

Herzog Glass was the first authorized LuxWall representative in Washington State. LuxWall’s Enthermal® vacuum-insulated glass provides high thermal performance in a thin profile for commercial renovations, energy retrofits, and new construction. For many retrofit applications, the existing window frames can remain in place, allowing the building owner to upgrade the glass without undertaking a complete window or façade replacement. LuxWall Enthermal products are supported by a 20-year limited warranty.

How we work

Experienced with Complex Commercial Projects

Commercial glazing requires coordination between architectural design, structural requirements, glass production, system fabrication, building-envelope performance, site access, and construction sequencing.

  • Preconstruction and budgeting
  • Design and constructability support
  • Shop drawings and submittals
  • Engineering coordination
  • Glass and system procurement
  • In-house fabrication
  • Project scheduling and logistics
  • Union field installation
  • Testing and quality-control coordination
  • Closeout, warranty, and ongoing service

Certification

Washington’s First NACC-Certified Glazing Contractor

North American Contractor Certification, certified architectural glass and metal contractor, certificate HEI01WA.

Herzog Glass was the first glazing contractor in Washington State to earn certification through the North American Contractor Certification program. NACC certification evaluates a glazing contractor’s quality-management systems, personnel qualifications, safety practices, and ability to consistently perform architectural glass and metal work.

Certification provides general contractors, architects, and building owners with independent confirmation that Herzog follows established processes for managing quality throughout a commercial glazing project. Our certification supports a company-wide approach to documentation, fabrication, installation, inspection, corrective action, and continuous improvement.

Selected work

Building the Pacific Northwest

Herzog Glass has contributed to many of the Pacific Northwest’s most recognized buildings, including the Space Needle, Seattle Convention Center, Climate Pledge Arena, and multiple University of Washington facilities.

These projects reflect our ability to coordinate complex glazing systems, demanding schedules, large field teams, and detailed architectural requirements. We bring that same level of planning and accountability to every commercial project, regardless of its size or visibility.

Working together

A Reliable Construction Partner

Successful commercial glazing depends on communication and coordination as much as installation. Herzog Glass works alongside the project team from initial planning through closeout to identify issues, manage changing conditions, and keep the glazing scope moving.

Our project managers coordinate drawings, submittals, material procurement, fabrication, field labor, safety, testing, and documentation. Our in-house facility provides additional control over system fabrication, custom components, and project-specific modifications.

After installation, Herzog’s service division remains available for warranty work, glass replacement, door and hardware repairs, planned maintenance, and future building modifications.
