Astragal Bar Windows

An astragal bar gives the attractive appearance of a Georgian window and is divided into multiple panes. Unlike Georgian window bars, which are set inside the sealed unit, astragal bars are fixed to the glass on the inside and out. Therefore, you get the traditional, crafted look of multiple panes on a single piece of glazing.

Handy Tips

Did you know that our energy rated windows will not only reflect heat back into your home but will also retain heat from solar gain.

Our astragal bars come in a range of finishes and colours, and can be fitted to any of our products, thus enhancing the look of windows and doors by giving them the traditional Georgian appearance of individual panes.

The bars are securely fitted with clips and adhesive pads that have been developed to stick to glass no matter what the weather throws at them.

Astragal bars are the perfect solution for anyone looking for a traditional Georgian appearance without multiple window panes – and without the high price tag.

Maximum Window Dimensions

Our window system can be used to produce almost any shape of size window. A sample range of styles and size limits are shown in the table below. The maximum dimensions shown may vary depending on the location of the installation and the local wind speed. The size of the window is governed by the limiting deflection of the glass and the hardware size/weight limitations. This will define the maximum length of the mullion/transom and the glass area.
