A thermal insulation structure for windows including a flat, transparent or translucent plastic sheet and a frame structure adapted to clamp the edges of the sheet and adapted to be magnetically attached to an existing ferromagnetic window frame or to a ferromagnetic or magnetic strip adhered to a window, window frame or opening. The frame structure comprises a U-shaped member and a magnetic strip secured to one prong of the U-shaped member or a L-shaped member secured to one surface of the sheet while the magnetic strip is adhered to the opposing surface of the sheet. The insulation structure is transparent to outside light and provides a simple means for significantly reducing conducted and radiated heat loss through the window and for eliminating window air infiltration heat loss.

An insulation structure capable of being attached to a window frame enclosing a primary window which comprises: a flat transparent or translucent sheet having an edge, a frame means comprising a U-shaped member of unitary construction having two prongs, said prongs adapted to enclose the edge of said sheet, a first strip having a first flat planar surface along its length selected from the group consisting of a flexible magnetic strip and a ferromagnetic strip, and a second strip having a second flat planar surface along its length selected from the group consisting of a flexible magnetic strip and a ferromagnetic strip, at least one of said first strip or said second strip being a flexible magnetic strip, said first strip being rigidly secured directly to or comprising one of said prongs, said second strip being secured to said window frame, said first strip and said second strip being positioned to directly contact each other with said first planar flat surface and said second planar flat surface contacting each other in face to face relation thereby to position said sheet between about ¼inch and 4 inches from said primary window and to form a continuous air-tight seal between said first strip and said second strip.
