Product details

Fold the opening back.

Dark aluminium bifold leaves partly folded across a garden-facing openingView full size

Cortizo Bi-Fold opens a room by folding the leaves to one or both sides of the opening. Its 73 mm frame distinguishes it from Bi-Fold Plus and provides a separate folding-door option within the selected collection.

The manufacturer describes arrangements from one to fourteen sashes, with a mullion-free 90-degree corner possibility for outward-opening configurations. The opening structure, leaf sequence and threshold drainage determine what can be used in an individual project.
