Double glazing unit SageGlass® Climaplus: 6.1EC-16-6

The SageGlass Electrochromic IGU is a type of dynamic glazing for use in buildings which tints automatically or on demand to control sunlight admission, controlling heat and glare, while maintaining a view to the outdoors and reducing energy consumption. The dynamic functionality is provided by the SageGlass electrochromic coating which is located on the cavity facing surface of the exterior lite of the insulating glass unit (see figure below). The SageGlass coating comprises multiple layers of ceramic materials of less than a micron thick that together, and upon application of a low voltage direct current, provides the ability to reversibly tint the glass to dynamically control the admission of the sun’s heat and light. SageGlass electrochromic insulating glass units are available in a range of product configurations according to customer specifications. This EPD is specific to the Double Pane IGUs. A typical IGU configuration is shown in the figure below. Each configuration comprises a support lite of float glass, the thickness of which depends on the application that is laminated to the 2.2mm device lite, a 2.2mm thick float glass lite on which the electrochromic coating is deposited (called the device lite), a third lite of float glass which is the inboard lite of the insulating glass unit (called a cover lite), the thickness and type of which depends on the application, and associated insulating glass materials which comprise metallic spacer, dessicant, sealants, laminating interlayer materials, and wiring
