Beautiful Georgian sash windows

The Georgian period was extremely long. It began in 1714 and ended in 1820, with the beginning of the Regency period. This means there are many stylistic differences in the period itself:

  • 1714 to about 1760 Palladian style
  • 1760 – 1790 Neoclassical style
  • 1790 beginning of Regency

All these styles are characterized in all instances by elegance, proportion and symmetry. Georgian sash windows from the Georgian era usually have the classical arrangement of three panes across by two up on each of two sashes, giving six over six panel Georgian Style Sash Windows. The upper and lower sashes slide vertically in separate grooves, counterbalanced by Sash weights on Pulleys & Cords. Later, as the Georgian Sash window manufacturing process progressed, the Sash weights have been replaced by Springs (Spiral balances). Hence, for the enthusiasts of traditional Sash window appearance and Sash window operations the traditional Box Sash Windows balanced with Weights & Cords are still being manufactured until today.

How to clean your sash windows

Ideally, sash windows should be cleaned twice a year, but it‘s a task most people tend to think of as spring cleaning. When you do clean your sash windows we recommend you don‘t clean your sash windows on a sunny day. This is because the sun will dry the soap on the glass and leave water streaks on your sash windows. To avoid this problem, better choose a cloudy day.

If you‘re using paper towels and glass cleaner for cleaning your sash windows, you are doing it wrong. All that rubbing isn‘t a good idea as you‘re just moving the dirt from one place to another and additionally creating a static charge on the glass, which attracts even more dust and dirt.

To clean the inside of sash windows we recommend a glass cleaner and microfiber cloth. This should be enough because inside sash windows are usually not as dirty as they are on the outside. For outside cleaning of sash windows you should choose a dish washing liquid mixed with water and use sponge. And then simply squeegee the solution off of your sash windows. This is pretty simple and does not lead to lots of dirty paper towels going into your waste bin.

The entry is a focal point of a house. And the front door is the first thing we see when we arrive and the last thing we touch when we leave. So there is no surprise that many house owners still like their front, external doors, made from wood.

Wooden external doors do offer much more design options than steel or uPVC external doors could ever do. Wooden external doors can be manufactured according to custom shapes and sizes, incorporating a big choice of moulding profiles, glazing options, carvings or differennt panel configurations.

Entrance doors made from solid wood are less affected by the elements. For example, pine external doors are relatively stable, light in weight and colour; Oak external doors are naturally stable, rot-resistant and heavy; alder is a good choice for rustic external doors – it has a fairly straight grain and a natural cherry like hue. There are numerous species of timber to choose from. Mainly it is a question of level of required durability and the available budget.

Another important point of consideration before purchasing wooden external doors or entrance door is the style of a house. If you own a Georgian era house, your external doors should be with six panels without glass.

Contemporary external doors usually are marked by clean horizontal lines in order to match exterior.

After all, your new external doors or entrance door should deliver highest performance, require low maintenance and offer highest functionality. Stork Sash Windows Ltd offers a large choice of timber external doors and entry doors that are suitable for both period or contemporary houses.

Georgian Style Sash Windows

Georgian style sash windows were one of the most important visual elements in buildings from 1714 till 1830. Georgian Sash Windows were always externally painted, usually off-white or pale stone colours and made from timber: native oak or similar hardwood. Early glazing bars were robust and big, often almost 40 mm thick to protect the fragile glass. Despite of all, the increasing oak usage for shipbuilding coincided with the bigger availability of cheaper softwoods from Baltic states and Scandinavia. So the Georgian Style Sash Windows design evolved: panes became thinner, the width of the glazing bars began to decrease. By the end of the eighteenth century, timber glazing bars were as little as ten millimeters wide.
Georgian Sash Windows which are installed in Georgian style houses, often has the classical arrangement of three panes across by two up on each of two sashes, giving six over six panel Georgian Style Sash Window. The upper and lower sashes slide vertically in separate grooves, counterbalanced by lead weights on cords. Later, as the window manufacturing progressed, the weights have been replaced with springs.
