A sealed window unit includes decorative muntin bars formed by pultruded strips of thickness very much less than the spacing between the panes of the window unit so that the strips can be interwoven and extend from one side to the other side for attachment to the spacer strips of the sealed window unit by pegs cut at the ends of the strips during a length cutting process.

A sealed window unit including decorative muntin bars arranged in a grid pattern, the unit comprising a pair of glass panes of equal dimension so as to have adjacent parallel edges, a plurality of spacer strips each arranged to lie between two adjacent edges of the panes to space the panes and a plurality of said muntin bars arranged in said grid pattern between the panes, each of said muntin bars being formed by pultrusion from a thermosetting material reinforced by glass fiber material extending continuously therealong so as to form an elongate solid body of constant cross section having a width sufficient to form a decorative appearance and a thickness less than one-half the spacing between the panes, and each having a locating peg of reduced width relative to the bar and of the same thickness as the bar on each end thereof for engaging and locating the end in an opening formed centrally of a spacer strip whereby each bar extends from one spacer strip to another between the panes and crosses at least one other bar to form an interwoven structure.
