Solar Innovations® Aluminum Sliding Glass Door Systems expand the view of any living space or commercial area. These systems can be used as external entryways or transitions between two interior spaces. Solar’s acoustical sliding glass door systems are the ideal solution for projects that have high sound transmission class (STC) requirements. Although acoustic values are typically specific to the glazing selection, the construction of the frame can greatly influence the acoustical performance. Solar’s acoustical sliding glass door systems allow for a 1 3⁄8-inch insulated glazing unit and are a standout product in the industry because they combine enhanced acoustical performance, superior thermal performance, and outstanding functionality.
