Service Overview
Curtain wall systems are among the most technically demanding elements of a commercial building envelope — requiring precise engineering coordination, careful fabrication, and experienced field installation to perform as intended over the life of the building. When any of these elements fall short, the consequences range from water infiltration and thermal performance failures to structural concerns and costly remediation.
A & A Window Products provides curtain wall services for institutional, commercial, and high-rise projects throughout New England — covering new construction, full system replacement, design assist coordination, and curtain wall repair and rehabilitation. With in-house engineering, a dedicated fabrication facility, and a union installation workforce, our team manages the full scope of curtain wall work from initial coordination through final installation.
Our curtain wall work is built around:
- Early design assist collaboration with architects and project teams
- In-house engineering and detailed shop drawing production
- Custom fabrication at our Woburn headquarters
- Experienced union installation crews
- Complex logistics management for high-rise, urban, and occupied building environments
- Curtain wall repair and rehabilitation for aging or failing systems

Why A&A Window Products
Design Assist Capability
A & A's in-house engineering team participates in design development alongside architects, construction managers, and facade consultants — providing constructability input, system coordination, and cost-effective detailing before shop drawings are produced. For complex curtain wall projects, early contractor involvement reduces RFIs, minimizes field conditions, and keeps projects on schedule. Harvard Gund Hall is a representative example: a design assist curtain wall replacement program involving 2,000 custom glazing units, triple-pane and hybrid systems, and an intensive summer construction schedule.
In-House Engineering & Fabrication
Curtain wall projects that depend on outside fabricators for custom components face lead time risk, quality control gaps, and limited flexibility when field conditions require adjustments. A & A's 16,000-square-foot Woburn fabrication facility — supported by an in-house engineering department using advanced CAD technology — gives our team direct control over custom panel production, unit fabrication, and delivery sequencing throughout the project.
Complex Logistics Management
High-rise curtain wall installation in dense urban and institutional environments presents access, staging, sequencing, and safety challenges that require experience to manage effectively. A & A has executed curtain wall work in environments ranging from active corporate headquarters and occupied university buildings to historic landmark properties — managing tight schedules, limited storage, material staging, and multi-trade coordination throughout.
Curtain Wall Repair Expertise
A & A's repair experience — including the rehabilitation of 21,000 square feet of failing curtain wall at MIT and multi-year curtain wall repair at TD Garden — means our installation crews understand how curtain wall systems fail and what it takes to fix them correctly. This repair-informed perspective makes our new installation work more deliberate and our replacement recommendations more credible.
Union-Trained Installation Workforce
Our glaziers and carpenters are trained through the Finishing Trades Institute of New England and the North Atlantic Carpenters Training Center. For curtain wall work — where installation precision directly affects long-term system performance — the quality and experience of the field workforce matters as much as the engineering behind it.
Established Since 1954
Seven decades of commercial and institutional glazing experience across New England, including curtain wall work on some of the region's most recognized institutional, corporate, and historic properties.
Performance & Compliance Considerations
Curtain wall systems must meet a demanding set of structural and performance requirements
Our in-house engineering team reviews applicable performance requirements during design assist and shop drawing phases, coordinating system specifications with architects, facade consultants, and manufacturers before installation begins.
