Abstract

An interior insulating window having a rigid frame extending about the perimeter of the window, the outer edge of said frame having foam strips mounted which provide a sealing edge. The aformentioned frame which may be composed of a variety of materials with little or no consideration to respected weights. The window to be inserted in said frame may be of a variety of transparent, semi-transparent, or opaque material with little or no consideration to respected weights. A system held in a vertical position within an existing window casing by the force exerted by the compressed foam strips on the top and side of the frame. Whereas thinner passive foam strips are mounted to the bottom and remaining side of the frame to complete a sealing edge about the perimeter of the frame. Whereas the aforementioned foam strips are composed of a material having sufficient indentation loan deflection and density to provide an adequate sealing edge. Since weight is not a limiting factor, modifications may be made to the basic window frame in favor of more ornate designs. The possible variety in designs offered to a perspective consumer make this system more marketable by comparison.

Dependent claims

In combination with an existing window casing, an interior insulating window comprising:

a. a rigid frame extending around the perimeter of a window pane, said frame comprising a top rail, a bottom rail, a first side rail and a second side rail,
b. a distinct foam strip of a first thickness secured along the periphery of each of said top rail and said first side rail,
c. a distinct foam strip of a second thickness secured along the periphery of each of said bottom rail and said second side rail, said first thickness being greater than said second thickness,
d. said casing comprising dimensions greater than said frame such that when said foam strips of first thickness are compressed said frame may be inserted into said casing with said foam strips providing a friction fit as well as an insulating barrier extending from said casing to said frame when in an inserted position,
e. said foam strips of second thickness being of a thickness which would not hinder insertion of said frame into said casing when said foam strips of first thickness are compressed, and being of sufficient thickness as to prevent compression, due to the weight of the window and the frame, of said foam strips of second thickness to a point which would adversely affect the friction fit of said foam strips of said first thickness.
