A method for fabricating muntin grid pieces includes steps that attach a pair of material strips to opposed edges of the muntin bar element. The material strips may be provided in side-by-side strips that may be separated an simultaneously applied to the opposite sides of the muntin bar element. The connection between the material strips and the muntin bar element may be made with an adhesive or a mechanical connection. The method allows the material strips to be connected to the muntin grid pieces before the muntin grid pieces are assembled into a muntin bar grid for a window.

DETAILED DESCRIPTION In view of the foregoing, it is an objective of the present invention to provide a method for fabricating muntin bars for simulated divided lite windows.
Another objective of the present invention is to provide a method for creating muntin bars for simulated divided lite windows wherein material strips are automatically sized, cut, and applied to the muntin grid elements that are then assembled into a muntin bar grid.
Another objective of the present invention is to provide a method for creating muntin bars for simulated divided lite windows wherein the muntin grid elements are roll formed from metal stock and automatically cut to length with the material strips being fabricated based on the data used to roll form the muntin grid elements.
Another objective of the present invention is to provide a method for fabricating a muntin bar grid wherein the person fabricating the grid only needs to provide the window size and the number of desired panes as well as to assemble the muntin bar grid after the individual muntin grid pieces are fabricated.
Another objective of the present invention is to provide a method for fabricating a muntin bar grid wherein muntin grid elements are provided and measured, with the measurements being used to fabricate the material strips that are then applied to the grid elements.
Another objective of the present invention is to provide a method, as above, wherein opposed strips of material are simultaneously cut to length and applied to the grid element.
Another objective of the present invention is to provide a method, as above, wherein the strips of material are formed with flaps that cover a portion of the muntin clips when the insulating glazing unit is assembled.
Another objective of the present invention is to provide a method wherein the strips of material include a non-extensible material to prevent the strips from stretching during installation.
Another objective of the present invention is to provide foam strips for use with muntin bars wherein the foam strips have a non-extensible material connected to the foam strip to prevent the foam strip from stretching when it is used around curves
