Timber Sliding Sash Windows
To meet the needs of your historic restoration or traditional new build, our Sliding Sash windows are the perfect match for your project. Designed for long life with low maintenance, our timber sliding sash windows provide the highest level of performance. For absolute authenticity we provide the traditional cord-and-weights mechanism in our Box Sash Window design. To suit modern reveal constructions we have the Spiral Balance design which utilises a spiral balance to offset the weight of the sash. We also offer the Tilting Spiral Balance design which enables the window to tilt inwards to allow cleaning from the inside.
With a choice of window layouts – square bay, angled bay and bow – and arch top, internal arch and arch fillet options, all of our sliding sash window designs allow high levels of customisation. We have a number of paint, stain, glazing and sash horn profiles to choose from.
To support our timber sliding sash window designs we have created an elegant furniture collection that provides simple, effortless operation and high security. The Sash Collection provides a number of finish options to allow a perfect match with other windows and doors in the property.
If you are looking to replace or retain, our sliding window designs are developed to the highest quality and are built with your needs in mind. From hotels to houses, facades to flats or conversions to cottages, George Barnsdale have a range of sliding sash windows for your specific needs.
Our unique collection of sliding sash windows will compliment the most specialised restoration projects and grace the grandest homes going. If the traditional sash window does not meet your needs, then we also offer the Yorkshire Sash, or horizontal sash window.

Timber Sliding Sash Windows - Key Features
Click on a marker to view this key feature in more detail.
Sash Fasteners (for High Security)
Fitted with hook fasteners as standard, our sash windows offer excellent security and weather performance with an authentic appearance. For maximum security, locking sash fasteners can fitted to the meeting rail, to meet Part Q requirements of the Building Regulations
Sash Stops (For High Security)
The windows are fitted with sash stops on either side of the frame so that whilst they can be opened for ventilation, the opening is restricted for security and safety.
Concealed Weather Seals (For Excellent Weather Performance)
Our innovative, concealed weather seals achieve a much higher degree of weather performance than most of our competitors’ products. Air-tight and discreet they do not detract from the authentic appearance of the window.
Accoya® Linings (Enhanced Durability)
Frame linings have always been a vulnerable point within timber sliding sash window designs. To overcome this design issue, and at no detriment to the window’s traditional appearance, we only use Accoya® timber linings which provide greater durability.
Astragal and Glazing Bars (Accurate Replication)
For period matching we can incorporate astragal and glazing bars to any sliding sash window design. As standard, we supply astragal bars for our Traditional Range designs, providing high performance at no detriment to the aesthetics. For listed properties the Historic sliding sash designs use a narrow solid bar to replicate original construction. Both astragal and glazing bars are available in a wide range of styles.
Sash Horns (Accurate Replication)
For an accurate match to the original, top and/or bottom sashes can be specified with sash horns. We offer several different horn types and, if required, we can match to existing designs.
Traditional Sliding Sash Windows
Designed for renovation and traditional new build projects, our Traditional Range combines period-matching styling with exceptional performance.
Across all three timber sliding sash designs –Box Sash, Spiral Balance and Tilting Spiral Balance – we offer high levels of customisation with a number of layouts and opening options supported by a vast selection of sash window furniture and finishes. All designs are glazed from the inside to provide enhanced security and improved weather performance.
Historic Sliding Sash Windows
To meet the needs of listed properties and those located in a Conservation Area, the Historic Range provides sympathetic replacement though accurate period design and original glazing methods.
Featuring narrow sash rails and thin frames to fit in the original openings, our Historic sliding sash window provides an authentic, high quality replacement. For accurate matching we offer several sash horns designs and a variety of profiles. A choice of single and narrow-cavity insulated glazing is provided.
