Glass curtain wall with seismic-resistant steel frame

Modern building codes demand more than just glass and aluminum.

In earthquake-prone regions and super-tall structures, facade systems must do more than remain attached to the building — they must safely move with it. During seismic activity, buildings experience dynamic displacement, torsional movement, and inter-story drift.

FOWALL Seismic Curtain Wall System

In earthquake-prone regions and super-tall structures, facade systems must do more than remain attached to the building — they must safely move with it. During seismic activity, buildings experience dynamic displacement, torsional movement, and inter-story drift.

Key Benefits

Life Safety Protection

Prevents dangerous glass fallout and facade panel detachment during seismic events.

Dynamic Sway Management

Designed for high-rise structures subject to wind-induced sway and seismic lateral drift.

The 4 Pillars

The 4 Pillars of Seismic Resilience

FOWALL's approach is built on four engineering principles that work together
to decouple facade movement from primary structural displacement.

Dynamic Movement Accommodation

· Inter-story Drift Design: Engineered horizontal and vertical joints that allow the facade to glide independently of the floor slabs.
 
· Multi-Directional Expansion: Specialized gaskets and sliders that accommodate lateral, vertical, and transverse displacements.

Reinforced Flexible Anchoring

· Ductile Connection Systems: Brackets and anchors designed to yield slightly under extreme loads, preventing brittle failure and maintaining structural attachment.
 
· Three-Way Adjustability: Precision-engineered anchors that accommodate structural tolerances while managing the energy of seismic oscillations.

Glazing Safety & Retention

· Structural Silicone Bonding (SSG): High-modulus silicone creates a flexible bond that allows glass to pivot within the frame during a tremor.

· Laminated Safety Glass: Engineered glass configurations that remain securely in the frame even if fractured, preventing falling debris.

Weather-tightness icon for curtain wall systems

Resilient Weather-Tightness

· High-Movement Seals: Specialized EPDM and silicone gaskets that retain memory and seal integrity after being compressed or stretched.

· Post-Event Reliability: Validated to maintain zero air or water leakage after the structural system returns to its original position.
