“Elegant and traditional, sliding sash windows in timber and oak are a beautiful addition to any property, often found on historic buildings, traditional properties and some country estates.”
Sash windows are windows which are made up of one or more vertically sliding panels or “sashes”. Although you may think of sash windows as a “traditional” feature found mainly on older homes, they are also often fitted on newer homes, either to match the style of surrounding buildings or simply to give a touch of class and elegance.
Our timber sliding sash windows are truly modern in terms of their construction and available features, but still have the charm and character of traditional Victorian windows. We manufacture all of our joinery on a computerised machine for incredible accuracy and repeatability.

More about our Sash Windows
Despite their traditional design, sliding sash windows are still the most effective way to naturally ventilate your home. Opening both the top and bottom sashes gives two separate openings at the top and bottom of the window, allowing hot air to escape at the top, while drawing cooler outside air in at the bottom of the frame.
Our timber sliding sash windows are truly modern in terms of their construction and available features, but still have the charm and character of traditional Victorian windows. We manufacture all of our joinery on a computerised machine for incredible accuracy and repeatability. The sophistication of our design and machining systems also allows us to account for a wide range of different features and designs. All of our frames and sashes are made entirely from hardwood, which makes them incredibly durable and results in a wonderfully smooth finish when painted or stained. Our frames also incorporate 28mm double-glazed units as standard for exceptional thermal characteristics, leading to long-term savings on your energy bills. Optionally, we can add all kinds of features such as sashes which tilt inwards for ease of cleaning on the 1st floor and above, enhanced security locking, decorative Georgian glazing bars in curved and straight designs, thinner glass units to better match existing windows or for listed properties, arched heads and more.
The efficiency of our workshop systems allows us to offer our windows at highly competitive prices, even competitive with UPVC windows, especially when you consider the whole life cost. UPVC frames are typically replaced every 30-40 years, whereas properly maintained timber windows can last 60 years or longer. Timber windows are also significantly better for the environment than frames made from other materials. UPVC and Aluminium both come from mining, which can be environmentally damaging in itself, and then further processing is required from the raw materials which uses lots of energy, releasing CO2 into the environment. When you install timber windows, they act as a “Carbon Sink”, since the trees absorb CO2 as they grow, and this carbon is then locked away in the timber for the life of the window frames.
Another great feature of our sash windows is that the weight of the sashes is counterbalanced by double-sprung balances concealed within the frame, giving around 75% mechanical assistance. This means that the most you’ll ever have to lift when opening the sashes is around one quarter of the full weight. This is an advantage over some of our competitors who only offer balances with 25% mechanical assistance. This is one of the things which allows us to use energy-efficient double glazing which makes the frames heavier. The balances we use have also been tested to over 20,000 cycles of use, which equates to over 50 years of once-a-day use.
Our sash windows can also be fitted as part of an orangery, conservatory or garden room. This can be a fantastic way of extending your property while keeping a traditional, classic aesthetic.

The History of Sash Windows
Sash windows have been around a long time and are sometimes referred to as hung sash windows. They are manufactured in a way that allows movable panels to slide under one another thanks to the seperation by narrow muntins. This type of window typically comes in a vertical or horiztonal sliding configuration which is sometimes known as a “Yorkshire Light”. The history of the sash window dates back to the 16th century where surviving examples at Ham House can still be seen.
It is not uncommon to find this type of window in victorian and georgian style homes which, when built used this type of window as standard. This type of window was often manufactured in sizes exceeding 1.2 meters in width and 1 meter in height, older examples were often in a rectangular configuration with window heights up to 2m.
The operation of the window relies on a counter-weight between the glazed panel (the weight is hidden within the window frame. The sash weight is connected to the window via a chain or string cord that runs over a pulley allowing the weight to assist with the incline and decline of the window. Modern versions of this window use spring balances which are also concealed and tend to be more hardwearing.
Materials used for frame construction include timber, oak or pine. Traditional sash windows were single glazed and had overlaying glazing bars (muntins). Modern versions are generally double glazed to improve thermal efficiency and to improve noise resistance. Double glazed versions have glazing bars overlayed on the outside of the glazing to give the appearance of multiple window units when really the glass pane is a single unit. Many traditional properties, old cottages and manor houses still favour single glazed options to maintain the appearance and property theme.
Thanks to modern wood treatment and enhanced manufacturing, old problems that plagued sash windows are history. Old versions of this Window type suffered from rot, water absorption, swelling and distortion of the frame leading to all sorts of problems including rattling windows, poor thermal efficiency and difficulty in opening and closing the window. New manufacturing techniques and wood treatment allow for much better weather resistance, rot and mould resistance which in turn prevents the window frames absorbing water, swelling and frame damage.
