G-Wall Bi-Fold Door

Innovative technology at its peak, with greater design and constructive flexibility

The GUTMANN G-WALL meets all architectural specifications, providing an above-ground, bottom-running configuration with various threshold options. Engineered for optimal load-bearing capacity, the hardware components and systems feature slender sightlines, oversized doors, and minimal profiles.

Doors can swing inward or outward with identical profiles. The sash and outer frame have the same depth, optimizing thermal efficiency.

This inline system features custom hardware, ensuring high performance and an aesthetically pleasing and robust door.
