Product details
A wide opening, with every fold considered.
Bi-Fold Plus develops the folding-door format with an 80 mm frame and 45 mm thermal breaks. It is a distinct option for extensions where thermal specification and the central frame detail are central to the design.
The doors can fold inward or outward, with configurations of up to fourteen sashes. The manufacturer publishes a mullion-free 90-degree corner option for outward-opening layouts. The usable layout depends on the opening, leaf weights, structure and threshold detail.
