Concealed Fastener Window and Curtain Wall Systems for Enhanced Architectural Performance

Concealed Fastener Window and Curtain Wall Systems for Enhanced Architectural Performance (Concealed Fastener Window or Curtain Wall Assemblies, Tech ID: 14‑008)

Technology Overview: This NJIT technology introduces a concealed fastener system for window and curtain wall assemblies that improves structural performance while delivering clean, uninterrupted exterior aesthetics. By relocating structural fastening components away from exposed surfaces, the system enhances durability, weather resistance, and visual appeal. The design supports modern architectural demands for large glass façades and streamlined building envelopes while maintaining compliance with structural and safety requirements.

Industry Pain Point: Conventional window and curtain wall systems rely on exposed fasteners that detract from aesthetics and are vulnerable to corrosion and weather damage.

NJIT Solution: This assembly system provides hidden structural fastening, improving longevity, appearance, and environmental resistance.
