Solar Innovations, Inc.’s onsite showroom contains many of the vast number of window and door systems that Solar manufactures, including the stacking wall system featured below. This system includes eight top hung panels that stack behind a polycarbonate door. One of the panels is an in-swing door with push/pull hardware. This allows users to not have to open the entire unit to enter the room.Solar’s stacking glass walls can be thermally insulated and used for exterior applications or as an interior wall, such as the one shown here. These units are typically designed in a 60 degree, twin trolley configuration, allowing one hand operation for stacking the panels.
