After coating the individual panes of glass with the layers described above, SAGE fabricates them into industry standard insulating glass units (IGUs). These IGUs are then installed into frames supplied by SAGE’s window, skylight and curtainwall partners or by a supplier chosen by the architect or builder. Once installed in a building, the SageGlass IGUs are operated by a control system designed by SAGE. The configuration of the control system can be customized depending upon the needs of the project: windows, skylights and curtainwall can be controlled by a building automation/control system, manually using wall switches, or a combination of the two. The SageGlass control system wiring conforms to the requirements for NEC® Class 2 circuit, and is powered by UL listed power supplies, ensuring that the entire system meets industry standards.
