Georgian Windows

Georgian Windows (circa 1714 – 1837)

Sash windows were highly sought after during the Georgian and Victorian eras. Often the more affluent property owners would have sash windows throughout the property. Those could not afford to do the full property would install sash windows to the front elevation and less expensive casement windows to the rear.

Generally during the Georgian period the manufacture of large panes of glass was not possible, this is why we see many ‘8 over 8’ glazing configurations (sometimes more on larger windows). As production of glass improved, the larger panes became more popular and ‘6 over 6’ became more fashionable. All of the sashes had slender glazing bars giving the sash itself strength whilst being a necessity due to available glass size.

We can recreate this look in one of two ways. Firstly, it’s fair to say that individual units of modern double glazing necessitate very thick and chunky looking glazing bars. We do not use this approach as we feel it detracts greatly from the aesthetics of the property.

False bar system

We can use a timber glazing bar adhesion system. To do this, when we order the double glazing we request that a grid is constructed between the two panes of the double glazed unit. Then in our workshop, we adhere ‘false’ timber glazing bars to the outsides of the glass. The inside timber bar carries the same decorative mould as the main sash and the outside timber bar is shaped to copy the angles of putty pointing. When all of these are together the slender look of the original glazing bars is achieved and when looked at from an angle, each section appears to be an individual pane due to the internal grid. This is an acceptable approach for use in conservation areas.

Specialist Glass

We can manufacture the sashes to carry high performance specialist double glazed units. These units have a slim perimeter seal enabling us to make solid glazing bars to exactly copy the original sashes. To obtain high performance values, these individual glass units are injected with inert gases which greatly improve their thermal efficiency. This approach has been accepted on many listed buildings.
