NanaWall Systems, the pioneer in operable glass doors offer sheer magic with their range of Glass rooms. The folding glass walls used for the glass rooms are precision-engineered to blend the line between windows and walls. A closed wall in a Glass room looks like a row of floor-to-ceiling windows, but a hidden track-and-roller system allows the entire wall to be opened as required. Glass rooms can be used in residential as well as commercial applications.
