Abstract

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.
