Colonial Windows Melbourne: uPVC Windows, Colonial Style

What are colonial look windows? Colonial look windows feature decorative glazing bars fixed within the insulated glass unit, creating the appearance of multiple individual panes. The bars divide the glass into a grid pattern — commonly four, six, or nine panes — giving the window a traditional multi-pane aesthetic without the maintenance or thermal compromise of individually glazed panes.

What is the difference between internal and external colonial bars?

Internal colonial bars are sealed permanently inside the double glazed unit between the two panes of glass. They cannot be touched or cleaned but never deteriorate. External bars are applied to the outer surface of the glass and give a more three-dimensional, authentic look, but require occasional cleaning. Windows Republic uses internally fixed bars as standard for their clean, maintenance-free finish.

Are uPVC colonial windows suitable for heritage homes in Melbourne?

Yes. Many Melbourne suburbs are covered by a Heritage Overlay requiring replacement windows to match the original divided-pane appearance. uPVC double glazed colonial windows with correctly proportioned glazing bars and slim frame profiles can satisfy council requirements while delivering modern thermal and acoustic performance. A planning permit may be required — Windows Republic can advise based on your suburb.

Do colonial bars obstruct the view?
