A supplemental window for fenestration suitable for use with existing windows. The supplemental window, in one embodiment, comprises a frame with plastic sheet material stretched across it. An attachment mechanism secured to the frame functions to fasten the supplemental window to an existing window. The attachment mechanism can be a suction cup or adhesive for example. A seal attached to the frame functions to trap a volume of air between the window pane and the plastic sheet material. An aesthetic covering and draft inhibiting mechanism are also provided. The supplemental window is configured such that the layer of trapped air is of an optimum thickness of 0.15 to 0.75 inches to maximize thermal insulation properties of the supplemental window.
