GONHO 75 series 90 degrees full opening save space enhanced ventilation accordion folding doors

Bi-fold doors, also called folding doors, consist of multiple panels that are hinged to each other and can be folded open and closed like an accordion. Often used as patio doors to enjoy unobstructed views. Their panels stack on the edge of the opening when open, so they take up less space than sliding doors.

When bi-fold doors are open they take up very little space meaning they cause virtually no disturbance to our home’s natural flow. Unlike patio doors, which must slide behind another window or door, bi-fold doors collapse back on themselves offering the benefit of opening up your wall completely.  

Exterior folding door systems provide the opportunity to bring the outdoors inside. And create an expansive space for entertainment or relaxation. Folding exterior doors open completely to blur the lines between indoors and outdoors. These doors give us the flexibility to extend our living space onto our patio or other outdoor entertainment area.
