Georgian Windows

Wooden Georgian Windows

Typical UK streets highlight the arrangement of Georgian windows in facades, their glazing design and detailing, and their opening configuration – sash or casement. These traditional timber windows are a great contribution to our national architecture. This is especially true of London, where most traditional street architecture and vernacular buildings depend upon basic classical rules of proportion and detailing.

Also, when knowing the historic development of window design and technology, and the impact of architecture, it is possible to see the charms of window heritage. All building structures are planned according to a number of elements – such as the environment, functionality, economics, trends or others – and this also applies to windows. Until the early 1900’s, most Georgian buildings were designed by the laws of classical proportion, adopting the features of the Renaissance movement across Europe.

Symmetrically arranged windows, centrally positioned hardwood entrance doors, French doors with glazing bars, vertical emphasis to rectangular window opens, and elegantly detailed window glazing that reflected the dimensions of the building. Terraced Georgian properties regularly have the door to one side. All of this formed a memorable coherent ‘national architecture’ that lasted until late 1950’s when modernist fashion strongly took hold and changed the viewpoint about how buildings should look.

Key Georgian Window Design Characteristics

  1. Classic Proportions: Typically, Georgian windows adhere to classical proportions of 1:1.6. i.e the height of the window 1.6 times its width.
  2. Large Sizes: The large sizes were used to maximise light and also to minimise the window tax in the UK at the time. The height varied between the floors, often getting smaller nearer to the roof.
  3. Glazing Bar Pattern: Georgian windows feature 6 over 6 glazing bar designs with single glass panes in each section. This is by no means a fixed rule as some windows can feature 15 and even 18 panels at times. These days, a single sheet of glass is used with simulated glazing bars (aka astragal bars) to maximise energy efficiency and give the illusion of multiple panes.
  4. Slim Profile: Maintaining a slim profile is crucial for maintaining balance and symmetry throughout the facade. A defining characteristic of Georgian homes is symmetry.

Refinement of Style

During the eighteenth century, Georgian sliding sash window design progressed in refinement as attempts tried to improve the capture of natural light coming into the rooms by minimising the amount of timber to glass, hence enhancing the field of view to the outside. As a result, the elements of the sash profile, the meeting rails, stiles and glazing bars turned into slimmer and more delicate frames.

As a definition of classical design, windows were thought to be seen as voids within even facades, producing reduced glazing bars and other components intended to be virtually invisible with the use of a dark paint colour. Georgian window designs became longer, extending almost to floor level in most influential public rooms. Small square glass panes were replaced by rectangular panes that followed the proportions of the window as a whole.
