A muntin assembly for an associated window glass. The muntin assembly includes a first muntin bar that defines a first pocket and includes a first cleat. The muntin assembly also includes a second muntin bar that defines a second pocket and includes a second cleat. The muntin assembly also includes a clip disposed in the first pocket and the second pocket so as to hook the first muntin bar and the second muntin bar together in an overlapping arrangement. Further, the clip momentarily deforms to accept receipt of the first cleat and the second cleat.

A window assembly includes a polymer (e.g., polyvinyl chloride, vinyl) window frame made and a glass unit carried by the window frame. The window frame includes a pair of jambs and an astragal that extends between and interconnects the pair of jambs. The jambs have a channel or slot sized to receive therethrough one or more end walls of the astragal so that at least a portion of said one or more end walls extend into a hollow cavity in the jambs that is in fluid communication with one or more weep holes of the window assembly. The one or more end walls of the astragal and channel or slot of the jambs define a flow path configured to channel water from the astragal, through the channel or slot in the jambs and into the hollow cavity such that said water exits the hollow cavity and the window assembly via the one or more weep holes.

A clip for supporting a muntin grid, a muntin grid, and a method of assembly is disclosed herein. The clip includes coupled together lateral and longitudinal members, each supporting bosses, and first and second arms respectively. The clip for coupling to the first and second muntin bars via first and second notches in the respective muntin bars. The muntin bars are formed by pre-notching and then roll forming, wherein the bosses support the first and second muntin bars when the clip is coupling the first muntin bar to the second muntin bar.

A molded door skin with integral divided light bars. The divided light bars are either true divided light (TDL) bars simulated divided light (SDL) bars or decorative grilles. The door skin includes a body portion and a divided light bar portion. The body portion and divided light bar portion are of one-piece construction which is preferably compression molded from fiberglass or other synthetic materials. Once assembled into a door with door glass installed, the divided light bars form a number of small windows for either simulating the appearance of traditional divided light windows in SDL applications, holding individual panes of insulating glass units in TDL applications, or for decorative purpose only.

The present application provides a mechanical connector adapted for coupling to a mating element, as part of muntin clip or a two part connector. The mechanical connector includes a body having at least one surface adapted for engaging a reciprocal surface of the mating element, wherein the at least one surface of the body of the mechanical connector slides across and frictionally engages the reciprocal surface of the mating element across a predefined distance during the coupling and decoupling of the mechanical connector relative to the mating element. The mechanical connector further includes one or more protruding elements, coupled to the at least one surface of the body of the mechanical connector, which extend in a direction toward the reciprocal surface of the mating element during engagement of the at least one surface of the mechanical connector with the reciprocal surface of the mating element, where the protruding elements is attached to the at least one surface at a first end of the protruding element and being free at the second end of the protruding element, and where the protruding element can separately flex along the length of the protruding element toward each of multiple directions including opposite directions. When the mechanical connector engages and slides relative to the mating element, the one or more protrusions are caused to flex in a direction that is substantially opposite a direction of the movement of the mechanical connector relative to the mating element along at least a portion of the predefined distance.

The insulated glass unit (IGU) that replicates a historic glass window includes a single simulated divided light glass pane, a low-e glass layer, and spacer grills disposed therebetween. True divided light glass window panes are scanned to obtain surface characteristic data, subsequently used to design a pane that includes slumped areas corresponding to the unique topological characteristics of antique glass, separated by flat areas. The flat surfaces provide for sealing the IGU with the spacer grills, while the optics of the original historic glass are preserved via the slumped areas. A mold of the designed pane is then 3D printed in furan resin sand, and a glass layer is melted over the mold to create a one-piece pane that includes the antique features. Accurate replication of these windows enables historic building renovation with modern insulated windows with less sealing while retaining the original appearance, providing improvements in longevity and efficiency.
