The typical parts of a sash window usually include two sashes that slide up and down (or side to side), one in front and one behind, in vertical grooves, counterbalanced by lead weights on cords.
The glazed area consists of a number of smaller panes held together by glazing bars. The number of panes depended on the era. Sash windows for historic properties must be chosen carefully to ensure you get the right period, as there have been several developments and style changes in sash windows over the years.
So, how do sash windows work? Opening sash windows is different than a usual window with a side-mounted hinge. A sliding sash window can be opened at the top or bottom, or both. Traditionally, they have no outward swing but modern designs tilt in and out for easy cleaning.
Sash windows operate via a discreet pulley system situated within the window frame. Weights are attached to a cord, which travels along the pulley. When you vertically slide the sash to open it, the counterweight from the sash weights holds it securely in position.
Glazing bars make a great sash window detail, bringing out the traditional charm that is much sought after by homeowners. There are 3 main sash window types to choose from; your choice will depend on which suits your home’s aesthetics and, potentially, which period it dates from.
Georgian windows are traditional windows dating back to the 18th and 19th centuries.
Georgian sash windows showcase a classic design with a ‘six over six’ pane configuration. This style captures the elegance and symmetry characteristic of the Georgian era.
Victorian sash windows feature an ornate and eclectic style prevalent during the Victorian era.
These windows will usually include a ‘two over two’ grid design. These windows can take on many forms including bay window formations.
Edwardian sash windows exhibit somewhat a blend with the Victorian style but are typically more simple in design and overall less grand and ornate in appearance. Edwardian sash windows come with a ‘six over two’ pane arrangement.
Horizontally sliding sash windows are sometimes called ‘Yorkshire Sash’ windows. Either one or two of the panes can slide open.
Traditionally sash window frames would have been made from wood, but today we have a lot more options to choose from.
uPVC sash windows are often used as a substitute for painted wood. uPVC windows are low maintenance and energy efficient and also come in a wide range of colours and finishes.
Off the shelf, uPVC is the cheapest option for sash windows, with timber costing as much as 40% more for the windows alone.
Aluminium sash window frames are more expensive than uPVC, but they are stronger which is better for security and durability. Aluminium windows are also recyclable and, when compared to wooden frames, need very little maintenance.
Composite sash windows are increasing in popularity with wood on the inside and clad with aluminium on the outside. This ensures your composite windows keep the classic look of wood internally, but are resistant to weather conditions and require virtually no maintenance externally.
Wooden windows are very durable, excellent insulators and if taken care of properly can last longer than the modern uPVC varieties. With the use of modern finishes (available in all colours or stains) sash windows in timber don’t have to be high maintenance.
Due to their unique characteristics among various window types and their intricate designs, sash windows tend to be relatively more expensive. Nevertheless, there are effective strategies to manage potentially high upfront installation costs. This includes making informed choices regarding materials and obtaining quotes from multiple window installation companies.

While sash contributes to the aesthetic appeal of your home, it also comes with its set of advantages and disadvantages. In the following sections, we explore the pros and cons of sash windows.
Beyond their aesthetic appeal, sash windows can bring a number of benefits to your property. These include:
There’s no denying that sash windows are both charming and elegant. Sash windows bring out the traditional appeal and can easily become the focal point of any home.
Suited to homes in conservation areas
For those in need of a window replacement and living in a conservation area or a listed building, genuine timber sash window replacement may be your only choice.
The sliding panes allow great ventilation control. Two sliding sashes with an opening at the bottom and at the top of the window enable you to create a flow of cool air through your home which is ideal in summer. The lack of hinges also means you don’t have to worry about a gust of wind slamming the window shut.
While sash windows have a timeless appeal, they are not without some disadvantages:
Traditional sash windows can be less user-friendly when it comes to cleaning. The intricate design and divided panes may make it challenging to access and clean all surfaces thoroughly. However, modern variations with tilt functions can alleviate this concern by allowing easier access for cleaning.
Sash windows, particularly those crafted with high-quality materials like timber, can be relatively expensive compared to some other window styles. The craftsmanship involved in replicating traditional designs and the use of premium materials contributes to the cost.
The costs of sash windows depend on:
The following table gives some approximate costs for the supply only of sash windows in white uPVC.
|Double glazed sash window cost|
|Size of window (mm)||Average cost per window (supply only)|
|600 x 900mm||£240 – £1,485|
|900 x 1,200mm||£300 – £1,600|
|1,400 x 1,400mm||£345 – £1,860|
For the same windows in aluminium, it’s likely the cost would increase by around £400 – £500 per window, and wooden windows could cost £400 – £800 more per window. For example, after some industry research, we found the following estimated costs, this time including installation.
|Double glazed sash window cost (per material)|
|Frame material||Average cost per window (including installation)|
|uPVC||£240 – £1,240|
|Aluminium||£315 – £1,615|
|Wood||£360 – £1,860|
