The Galvanizing Leaps in Advanced Super INsulating Glass (GLASING) program supports small-scale research and development of high performance Insulated Glass Units (IGU) to improve the energy performance of windows in new and existing buildings. GLASING technologies will achieve more than three times the thermal insulation of currently available double-pane IGU technology at competitive cost and optical performance. Specifically, GLASING projects will focus on rapid manufacturing of vacuum insulated glazing, aerogels, and other technologies that increase thermal resistance values in windows. If successful, GLASING projects would produce more economical, high performance IGUs, improve the energy performance of buildings, and reduce strain on the grid, freeing up power for other uses, ultimately improving energy efficiency and reducing dependence on foreign energy, thereby increasing U.S. energy security.
