Triple insulating dynamic glass

Sage Electrochromics Inc., Faribault, Minn., developed a triple-pane window with electronically tintable dynamic glass. Tests show the dynamic, triple-glazed glass has an insulating R-value higher than 8, compared to an R-3 value typical of most low-emissivity double-pane glass. Combining super insulation with the glazing’s dynamic tinting capability provides a 16 percent energy improvement over static triple pane glass with low-E, and more than 50 percent improvement over single-pane glazing. The product is ideal for new construction and retrofit, primarily in hot climates, according to a company release.

Sage's dynamic tinting technology uses nanotechnology that can be changed electronically to manage daylighting. The technology saves building energy by managing solar heat gain, while enhancing occupant comfort and well-being by eliminating glare, according to the release.
