An interior storm window construction which is formed with a pair of identical window sashes affording the reversal of the window sashes and a frame comprised of four frame members, three of which are identical in cross section and one of which varies in depth to permit easy insertion and removal of the window sash from the frame. The frame members are formed to be easily adapted to out of square existing window casings. Each of the window panes of the window sashes are coated on one surface with a reflective material, the material on each window pane of the window construction being on a surface which is opposite the coated surface of the other window pane. Each window sash is adapted to slide within the frame formed by said frame members and they interlock along an adjacent edge to afford a seal and support along said locking edge.

An interior storm window construction comprising a pair of identical and reversible window sashes having window panes which sashes, when placed in a frame, will interlock at the adjacent edges to seal and provide a mutual support for the sashes, and a frame structure adapted to form the frame for the window sashes, said frame comprising four frame members which are joined together at their ends and adapted to fit in a window casement and define a rectangular opening, each of said frame members being formed of a polymeric material and being formed with a pair of parallel longitudinally extending channels adapted to receive an edge of said window sashes and said channels each having means for adjusting the position of the frame member with respect to the window casement supporting the same to seal the frame members with relation to the window casement and having openings to accommodate permanent fastening members to secure said frame members to the interior of the window casement to define a rectangular opening, one of said frame members being formed with a cross-section differing from the other three said frame members to afford a channel of increased depth for forming a top frame member.
