A window construction includes longitudinally channeled framing strips of right angular cross section attached to the four faces of a window casing or to a storm door window opening. Boundary edge portions of a pane closing the window opening are attached to the framing strips by resilient angular bead strips. The pane may comprise either a flexible plastic membrane, a rigid or semi-rigid self-supporting sheet or screening. The bead strips include two long bead flange portions extending at generally right angles from a body portion and a short rib portion extending from the outside corner at the intersection between the two bead flange portions. The rib portion and one bead flange portion are squeezed into opposed grooves in the channel portion of a framing strip to compress the pane in position against at least one inside surface of the framing strip.
