Georgian architectural design including Georgian Sash Windows is associated with orderly elegance, symmetry and proportion. Carefully balanced timber windows and doors were essential components in creating a sense of grandeur.
A walk around Bath, Cheltenham, Edinburgh or Leamington Spa will reveal fantastic examples of Georgian architecture. Filled with rows or crescents of two or three-storey townhouses, these cities still hold appeal for those with an eye for aesthetics.
This style was known as Palladian and it is based on the classical order of ancient Roman and Greek design, as described by Italian architect of the time, Andreas Palladio. In any Georgian property, you will see a large wooden, painted front door, positioned in the centre of the Ground Floor. Wooden, multi-pane, sliding sash windows were placed symmetrically on either side and above.
Columns may be included in the design, but otherwise, the rectangular buildings are typically free from elaborate detailing. The simplicity adds to the sense of a timeless classic.
Sliding sash Windows in Georgian Properties
Sash window design existed before George I came over from Germany to begin the Hanoverian reign in 1714. They comprise of two window frames, which overlap each other as they open. A pulley operates counterbalance weights which pull the lower frame upwards or the upper frame down. The frames contain multiple small panes of glass, held in place with Georgian Bars.
Sliding sash windows are hung from the top corners, rather than the side. This factor helps to minimise distortion. With a little maintenance, these timber sash windows can be incredibly long-lasting and that is why original examples still exist today.
Georgian sash windows are set back from the façade of the property by 4”. The sash box is positioned within the wall, behind the outer layer of brickwork. Window sills are also a feature of the design. These specific requirements were not part of the Palladian style. They were made necessary by the London Building Acts of 1667, 1709 and 1777.
Wooden Windows and the London Building Act
In 1666, the Great Fire of London spread rapidly through the capital. It destroyed 13,200 houses and 87 churches, along with many other buildings. The London Building Act was prepared to ensure that rebuilding the city would ‘elevate London to the heights of modernity’ and prevent future devastation.
Window sills were the first compulsory requirement to be introduced. Later, recessing and enclosing the wooden window frame became necessary. These measures aimed to reduce the spread of fires. Although wooden windows and doors were used, all new buildings had to be constructed of brick or stone, rather than timber.
Replacing Sash Windows from the Georgian Era
If you live in a Georgian house, your property may be listed or located within a conservation area. You will likely need to seek planning approval before replacing original sash windows. If possible, you will be encouraged to repair original windows. Only those which are beyond repair are likely to be approved for replacement.
To approve replacement windows, planning departments will request evidence that the glazed windows will be sympathetically replaced. This involves the use of traditional materials and techniques. As experienced joiners and specialists in sliding sash windows, Hinson Custom Made can assist with preparations for Planning applications.
Our custom-made windows will use traditional woods, profiling and finishes. We fit the wooden window frame with Georgian glaze bars and small single-glazed panels of glass, rather than astragal bars.
What are Astragal Bars?
As mentioned, the window style in Georgian times was made up of small panels of glass, held in place with bars. Some modern windows aim to replicate this style by using a single pane of glass and applying wooden bars onto the pane to create the look. Georgian bars part of the frame, holding individual panes in place. This is the authentic method and is likely to be a condition of replacement Georgian windows in conservation areas.
