SageGlass is a Saint-Gobain subsidiary developing smart glass solutions for buildings.


SageGlass is a manufacturer and seller of electronically tintable smart glass, such as electrochromic glass or dynamic glass, designed for windows, skylights, and curtainwalls. The company's electronically tintable glass allows thermal and visual comfort with reduced energy demands of the building and is intended to eliminate the need for blinds and shades. SageGlass was formerly known as SAGE Electrochromics and was founded in Faribault, Minnesota in 1989 by John Van Dine. In November 2010, SAGE Electrochromics was acquired by Saint-Gobain, and it was renamed SageGlass and operates as a subsidiary.

Smart glass

SageGlass's smart glass products are developed to change their tint in response to the sun to provide unobstructed outdoor views while also offering occupant comfort and reducing a building's cooling needs and thereby save on energy costs. This replaces or removes the need for blinds, shades, or e-glass, which can all reduce or obstruct an occupant's view. Further, the SageGlass products utilize intelligent control systems through mobile applications, which allow users to set different settings or allow them to set the glass to automatically respond to light conditions.

The glass is capable of being built in different shapes and sizes and can be done in different configurations, such as double and triple pane units. SageGlass offers a variety of glass color options. The glass uses electrochromic glass that is capable of tinting on-demand and adjusting tint for comfort and energy efficiency. These efficiency savings have been suggested to reduce the cooling load for a building by up to 20 percent and HVAC requirements by up to 30 percent.


SageGlass's LightZone allows users to create up to three tint zones within a single pane of glass. This enables users to let in or block out the right amount of light, as needed by the user for their personal comfort.


SageGlass Harmony is a glazing solution that provides precise glare and daylight control with a smooth visual aesthetic through a natural, in-pane tint transition. This system offers the same benefits as SageGlass's other products but also features a gradual in-pane tinting rather than the full-pane tinting of their traditional glass products, or the three-zone tinting as with SageGlass's LightZone products.
