Built for Views,
Performance, and Project Demands

Window walls offer a clean, modern alternative to curtain wall systems—installed slab-to-slab for improved thermal performance and simplified installation. At Northern Glass Inc., we deliver unitized and stick-built window wall systems engineered to suit each project’s structural, acoustic, and energy requirements.

We work closely with architects and contractors to ensure proper alignment with floor slabs, slab edge covers, and adjacent glazing or cladding systems.

Delivering Window Walls With Precision & Efficiency

Our approach to window wall delivery combines in-house fabrication with coordinated field installation, ensuring seamless execution at every phase.
Our process includes:

Early Design Coordination

We review structural requirements, transitions, and system compatibility during the preconstruction phase.

Detailed Shop Drawings

System drawings include anchor placement, sill/jamb details, and integration with slabs or architectural finishes.

In-House
Fabrication

Frames and glass are fabricated to meet specified tolerances and sequencing needs.

Expert
Installation

Installed by union glaziers who understand the unique structural and waterproofing needs of window wall systems.

Closeout & Performance Review

Final checks ensure alignment, weatherproofing, and visual consistency before handoff.
