When closed, the NanaWall SL25 All Glass System allows unobstructed views while providing wind protection for a balcony, stadium suite, or other similar application. This system offers the designer new dimensions in creating large, exterior glass walls that can be opened. In apartment settings, for example, the SL25 effectively increases apartment space, providing high-rise residents with a more functional and comfortable balcony area in which to relax, entertain, or set up patio gardens.
