Up until the early 20th century it was more economical to use smaller panes of glass, the smaller panes were cheaper to make. Now we can manufacture much larger panes of glass (5m or more!)  but if you want that smaller paned look to blend with your design then we can make windows to suit.

 

Colonial bars look good in historic sunrooms and Victorian or Edwardian conservatories, sunrooms and orangeries. We make two different kinds of colonial bars:

 

A “Vienna” colonial bar uses a larger pane which is not acutally divided. We fit little spacer between the doubles panes and then timber colonial bars are glued onto the glass.

“Structural” colonial bars are more traditional with many smaller panes of glass being joined to give the lattice or diagonal effect.
