Cortizo – Bi-Fold Plus Door

Folding Door System – 80 mm Frame

Define spaces without losing the connection between them. Our 80 mm frame folding door system delivers smooth, wide-span openings with strong thermal and acoustic insulation — built around a 45 mm thermal break and glazing capacity up to 48 mm. A slim 110 mm central junction means more glass, less frame, and maximum natural light.
