Precision-Engineered Entry Systems for High-Traffic Commercial Environments

Project: Tobin Montessorri
Location: 191 Vassal St., Cambridge, MA
Architect: Perkins Eastman
General Contractor: WT Rich

FEATURED PROJECT

Tobin Montessori

The Tobin Montessori / Vassal Lane Upper Schools are a massive four-story, 359,100-square-foot building designed by Perkins Eastman. The schools, completed in December of 2025 by W.T. Rich for the City of Cambridge, involved a wide variety of the work we do at A & A Window Products, including curtain walls, interior storefront, specialty glass, and entrance doors.

Specialized thermal glass used in windows and entrance systems helped the City of Cambridge meet its Net Zero Action Plan. These entrances were designed to be fully ADA compliant and include automatic operators, capable of withstanding hundreds of students rushing through every day.
