Abstract: A water-proof window flange is of an elongated, extruded shape. In an end view, it includes a vertical first member, a horizontal second member extending forwards orthogonally from an intermediate position on the vertical member, and a third member extending backwards from a forward end of the horizontal second member. An inner end of the third member is positioned below and forward of a lower end of the first member. The top end of the vertical first member is for being positioned between a siding and subsiding of a wall. The bottom end of the vertical first member is for being positioned on top of a window frame. The inner end of the third member is for being positioned in front of the window frame, and below a top edge of the window frame. The top of the vertical first member is positioned far above the lower edge of the siding to prevent rain water from seeping around the top of the window flange.

Abstract: A glazing bead adapted to secure a second, larger thickness of insulated window in a window frame designed to normally receive a first, smaller thickness of insulated window. The glazing bead comprises a plastic extrusion having a resilient, arcuate wall member which engages the window and/or the window frame. Extending outwardly from the wall member is a folded leg member which is inserted between the window and the window frame, thereby compressing it and urging a locking flange on the folded leg member into engagement with the glazing lip on the window frame to secure the glazing bead and the window in place in the window frame. When the glazing bead is snapped into place, the arcuate wall member is compressed and thus resiliently urges said locking flange laterally towards and into engagement with said glazing lip on said window frame. This compression of the resilient wall member also tends to effectuate a seal between it and the window.
