Sash windows



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 offers much more design options than steel or PVC external doors do. Wooden external doors can be manufactured by custom shapes and sizes, incorporate big choice of molding profiles, glazing options, carvings or 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 color; 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 is a numerous choice of timber to choose. Mainly it is a question of durability and the price.

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. Victorian era house external doors often have a single pane or leaded glass in their tops and moldings below. Contemporary external doors usually are marked by clean horizontal lines in order to match exterior.

After all, your external doors or entrance door should bring a high performance, low maintenance and functionality. Stork Sash Windows Ltd has 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.

The Victorian era lasted from the mid-1800‘s to the start of the 1900‘s. During this period the size of the windows began to grow in order to give more light to the rooms and allow access to the newly fashionable balconies. Many sashes from the last century lowered their sills to become full-length or even were replaced by French windows.
Improved methods of manufacture let the glazing bars to decrease and made it less expensive. By the mid-century most sashes either had only a single, central glazing bar, or none at all. Because of increased weight of the plate glass and the loss of strength from the lack of glazing bars, „horns“ were invented.

Double Glazed Box Sash Windows


The double hung sliding sash window was introduced to the UK in the 17th Century, Christopher Wren was an early proponent of this style and it featured heavily in his plans to rebuild the capital following the Great Fire of London.
Glazing bars were a common device in pre-Victorian architecture, in many ways Georgian and Regency styles are synonymous with this feature. The reason for their inclusion was not however, to add visual interest to the property‘s elevation, the truth is much more prosaic. Before glass manufacturing technology advanced sufficiently to allow the production of large panes, the maximum size of a pane was determined by the lung capacity of the glass-blower.
The material of choice for the majority of parts was traditionally slow-grown Baltic softwood with, in better quality work, hardwood specified for the cill portions.
Bringing sash window design into the 21st Century, your windows can be produced to be as authentic as possible to their original counterparts but with much more efficient and advanced technologies.
Double glazed box sash windows are provided with weights and cords to hold it in a place in any opening position: the sash weight is connected to the window frame by a chain (metal) or cord (nylon or cotton/hemp or other material) that runs over the pully at the top of the frame. Sash chain might be selected to negate the requirement for cord replacement and also better handle the increased weight of the sashes – a long-term investment.
Furthermore, the weight of modern double glazing packages is considerably greater than the original glass and might require, on some windows, a weight enhancement using lead instead steel.
The trickle ventilation to be machined into the frames is not recommended. This feature is intrinsic to the design and the application of plastic vent covers devalues integrity of the product. There are many ways to provide alternative ventilation, your architect or building contractor should be able to guide you in this.
In conclusion, the box frame is most ideal for town and city living. Unlike casement (hinged) styles of window, the sashes of a box frame do not impede traffic passing by when they are open, they can be securely locked and their proportions are extremely variable, making them suitable for almost every size of opening.
