These contemporary exterior folding doors from NanaWall are incredibly cool. The NanaWall modern doors provide a great alternative to the traditional door. This vanishing wall lets you bring the outdoors in and connect to nature while still offering essential protection from the elements. The NanaWall features collapsible pleated screen panels sliding on a single 1/4-inch-high by 3/4-inch-wide floor track, which fold open effortlessly to reveal unobstructed views of the surrounding scenery, whether your home sits on a mountain, in a valley or high up in an urban condo with city views as far as the eye can see. Even when closed, these stylish folding doors feature glass and a barely-there frame that lets you appreciate the views from every angle.
