Georgian Windows

Georgian Windows from Reliant Windows


Modern Georgian windows have the elegance and style of tradition, but also exhibit performance, improving home security and a high level of thermal efficiency compared to their predecessors.


Astragal bars on the glass and Georgian bars inside the glass are two options for Georgian windows. Astragal bars are planted on to the window sealed glass unit both internally and externally. The effect is to project a window with separate panes of glass, giving the window a real traditional period feel.


Differently, Georgian bars are set inside the glass sealed unit, which means that they are contained between the panes of glazing. Rather than being added to the outside of the glazing, they are sealed within the unit interior.
Both options will suit and enhance a variety of home styles, both traditional and contemporary. 


The choice is a personal preference and the most important element is that both options are available to give you creative control of your home with Reliant Windows.

If you would like to discuss your Georgian window requirements, call us today on 0121 500 0500.
