Cellular shades
Windows and doors make up for approximately one-third of a home’s total thermal loss, according to the Natural Resources Defense Council. This applies to heat loss in winter, and entry of undesired heat in summer. When air inside the room comes in contact with windows, it is cooled or warmed. By convection this air then circulates around the room. Cell shapes in the blinds hold trapped air and create a barrier between the window surface and the room. Shades, however, provide only slight control of air infiltration.
