Historically, large pieces of glass used to be expensive to manufacture so windows were made with smaller panes puttied into frames—known as true-divided light. As glass technology improved in the 20th century and energy efficiency became more of a consideration, these multi-paned windows were replaced by larger single pane varieties. Today, you can get the benefits of energy efficient glass with the historic look of divided light, including removable grilles.
