A novel method of making a double glazed impact resistant window is provided. The method includes forming a window sash that delineates a mounting space for mounting a first pane and a second pane opposite and parallel to and spaced apart from each other, the sash having an integral spacer that forms a sealing surface of the mounting space for each pane and adhering or coating at least two layers of a durable transparent polymer film to a surface of the first pane such that the at least two layers are not adhered or coated in directions that are parallel to one another. The method further includes conforming the pane to the size and shape of the mounting space, mounting the first pane in the mounting space with the film covered surface of the pane facing the sealing surface of the integral spacer, conforming the second pane to the size and shape of the mounting space, wherein the second pane is free of the durable transparent polymer film, and mounting the second pane in the mounting space.
