Kolbe Windows & Doors has added vacuum insulating glass (VIG) options from LuxWall to its Ultra Series and VistaLux WD Line windows and doors. According to the manufacturer, a small, virtually airless vacuum space between the panes of glass improves thermal insulation, comfort, and energy efficiency.
