What is a box sash window and what is the difference between a box sash window and a sliding sash window?
Are you wondering what the difference a box sash windows and sliding sash window is? If so, here at The Rose Collection, we have put together this handy guide to help you understand the difference between the two.
What is a sash window?
Sash windows are a hugely popular home improvement option for house and period properties throughout the UK. The elegant sash window design has been a favourite amongst homeowners since as early as the 17th century and continue to be popular today.
This window design is characterised by the sliding “sashes” that move vertically to open and close the window. There are several distinct, historic features of sash windows that make them stand out from other window styles, hence why they are the most highly sought after window style for period properties.
The difference between box sash windows and sliding sash windows is purely mechanical. The windows themselves can be nearly indistinguishable from each other visually. However, there are some distinct differences that will help you identify the difference between the two.
What is the difference between a box sash window and a sliding sash window?
A box sash window is a traditional sash window style. Sometimes referring to as a “hung sash” or “sash and case”, the vertical window box houses a system of ropes and a pulleys on a piece of sash cord which provides an effortless lifting of the sashes, even for heavier windows. This opening system would be built into the side of each of the windows, hidden from view so as to maintain the visual appearance of the sash window.
Box sash windows are a traditional way for sash windows to be manufactured and are often chunky and heavy in nature, meaning they are usually used for larger windows, but also work well for smaller windows styles. Over time, sash cords can become worn and need replacing which can be the reason for many timber box sash windows getting stuck or being difficult to open.
Over the years, the use of traditional weights and pulleys has been reduced to use a more up-to-date method of operating. Spiral balances are now used in many sliding sash windows which includes the use of springs instead.
Sprial balances are a modern alternative to weights and pulleys and provide a more simple mechanism for sash windows and modern alternatives.
With some manufacturers designs, however, the spiral balances are often visible and may impact the appearance of the sash window. A manufacturer of high quality uPVC sash windows with spiral balances will often pay special attention to creating more authentic sightlines that mimic the appearance of box sash windows effectively.
Should I choose a box sash window or a sliding sash window?
Whether you should opt for a box sash window or not is entirely dependant on what it is you hope to gain from your sash windows.
Box sash windows are the traditional sash window option for timber sash windows and do offer authenticity. However, newer methods of opening sash windows were developed due to the costly and high maintenance nature of weights and pulleys. Sash cords can become worn quickly and cause box sash window opening issues. Advancements in sash window technology have allowed sash window manufactures to offer authentic sash window designs that offer modern performance benefits.
Spring balanced sash windows are the sliding sash window option for many budgets. It is a modern sash window option that will give your property a traditional appearance and will fit well with most building styles. Furthermore, here at The Rose Collection, our sash windows have been approved for listed building and conservation areas due to their authentic appearance.

The iconic vertical sliding operation is at the heart of sash window operation and we have worked hard to emulate this is in the most authentic way possible. The torsion balance is concealed inside a plastic tube and hidden within the window frame. The loaded spring is adjusted to create the perfect tension for a smooth but firm opening every time.
These balances are far more hard wearing than weights and pulleys and therefore are less costly and time consuming to maintain. Furthermore, they are much easier to replace should they ever need maintenance in the future.
