What is the difference between Astragal and Georgian bars?
By Jamie from Modern UPVC windows team
Georgian and Astragal bars mimic the traditional Georgian style with the effect of multiple panes of glass, by appearing to divide each pane into multiple panes.
Georgian bars are 18mm thick and set internally between the glass panes of a glazing unit. The surface of the glass on both sides remains smooth for easy cleaning, as the bars are placed inside the glazing unit.
Astragal bars are more substantial 20mm thick and are fitted to the outside, in between and the inside of double glazed units. They stand proud of the glass on both sides, replicating even at close-up the traditional Georgian style.
Both Astragal and Georgian bars match the window/door colour and do not compromise the insulating abilities of the glazing unit.
