Sash windows have been a beloved architectural feature for centuries in England, gracing homes with their elegant appearance and functional design. Yet the beauty and efficiency of a sash window are not just defined by its frames and glass, sashes contain many other components. High quality sash window hardware plays a vital role in the window’s operation, security, and overall aesthetic appeal. From traditional brass pulley systems, to contemporary chrome fasteners, each piece of hardware is integral to the function and style of the window.
At Traditional Sash Windows and Carpentry, we offer a wide range of sash window hardware options to suit every taste and period style. In this guide we will explore the various types of sash window hardware, their materials, design options, and how to choose the right components for your sash windows.
Sash Lifts: These are positioned at the bottom of the window sash, these small handles allow you to lift and lower the sash with ease. Sash lifts come in various shapes and sizes, ranging from simple flat bars to more intricate curved designs.
Sash Fasteners: Sash fasteners secure the two sashes together when the window is closed, providing safety and preventing drafts. Common designs include Fitch fasteners, claw fasteners, and Brighton fasteners.
Sash Bars and Stops: These prevent the sash from sliding too far, providing a limit to its movement. Sash bars often add to the traditional look of the window, with options for both internal and external bars.
Pulleys and Weights: Pulleys, combined with sash cords, are located inside the frame and enable the smooth sliding motion of the window. Without pulleys the widows would be stiff and heavy. Counterweights are hidden in the frame, balancing the sash and making it easy to open and close. Without the weights, large sash windows would be very hard to open!
Sash Window Locks and Restrictors: These secure the sash in a partially open position or in a fully locked state, enhancing their security. Modern restrictors can also prevent windows from opening beyond a set limit, this is important when above the ground floor as it increases the safety for children or people at risk.
Handles and Catch Plates: Handles are mounted on the inside of the sash, allowing for easy opening and closing of heavy sash windows, while catch plates help secure the sash when closed.
Sash lifts are installed at the bottom rail of the sash and are used to raise and lower the window. They come in various shapes, including classic half moon lifts, flush lifts and traditional bar handles.
Half Moon Lifts: These are a classic choice, the lifts have a curved, half-moon shape that offers a comfortable grip with your index fingers.
Bar Handles: Ideal for heavier or larger sashes, bar handles provide additional leverage over half moon lifts and a more traditional appearance.
Flush Lifts: Discreet and simple, flush lifts sit nearly flat against the sash, making them a perfect option for minimalist designs, however these are not surable for heavy sash windows.
Sash fasteners, or locks, come in a variety of styles, each offering different benefits:
Fitch Fasteners: A popular choice for their simple, streamlined appearance, Fitch fasteners are operated by turning a central knob to lock or unlock the sashes, which prevents unauthorised access from outside.
Brighton Fasteners: Characterised by their delicate curved arm and decorative base, these are ideal for period properties or listed buildings.
Claw Fasteners: Featuring a claw like mechanism that locks the sashes together, these are the most robust and secure type of fastner.
Pulleys are essential for the smooth operation of a sash window, reducing friction and enabling the sash to glide effortlessly. They are typically made of brass or steel and come in single pulley or double pulley designs.
Sash bars break the window up into smaller panes, contributing to the traditional sash window look. They can be crafted in various grid patterns, such as Georgian grids or Victorian styles. Sash stops, on the other hand, are used to restrict the opening distance of the sash, providing added security and child safety when above ground level.
Window catches and restrictors offer additional functionality and safety. Restrictors limit how far the sash can open, reducing the risk of accidents. These are particularly useful for upper floors and family homes.
Brass: As a traditional favourite, brass hardware adds an authentic period feel to sash windows. Available in polished, satin, or antiqued finishes, brass is both durable and visually appealing. Regular polishing is recommended to maintain there lovely sheen.
Chrome and Nickel: Chrome and nickel hardware offers a sleek, modern look. With their shiny, reflective surfaces, these materials are ideal for contemporary properties. They are also highly resistant to corrosion, making them suitable for British coastal homes or high humidity environments.
Satin and Polished Steel: Steel hardware is robust and resistant to wear, making it the best choice for high use windows. Satin and polished steel finishes add a sophisticated, understated elegance to any window style.
Cast Iron: Cast iron hardware evokes a sense of vintage charm, perfect for rustic and period properties. It’s typically finished in black or antique bronze and is heavier and more tactile than other options.
Bronze and Antique Brass: These finishes have a rich, aged appearance that enhances the heritage look of traditional sash windows. Over time, they develop a unique patina that adds character and history to the hardware.
Painted Finishes: Some hardware pieces can be painted to match the frame or existing décor, providing a cohesive look. This option is popular for those looking to maintain a subtle, integrated style.
Traditional Styles: Traditional hardware is characterised by their intricate detailing, classic finishes like polished brass, and shapes that complement period architecture. Victorian and Georgian properties for example, benefit from hardware that mimics the original designs of the era, such as ornate Brighton fasteners or classic Fitch fasteners.
Contemporary Styles: Modern hardware designs tend to be more minimalist, focusing on clean lines and sleek finishes like polished chrome or satin nickel. Contemporary sash lifts and fasteners often have a more streamlined look, blending seamlessly with the modern interior.
Heritage and Period Reproduction Hardware: For historical properties, reproduction hardware crafted to original specifications can maintain the authenticity of the building while offering modern functionality. These pieces often feature intricate patterns and finishes that mimic the look of aged or hand forged metal.
Bespoke Hardware: For a truly unique appearance, bespoke hardware can be custom designed and manufactured. This option allows homeowners to incorporate personal tastes or match existing fittings that are no longer available.
When choosing sash window hardware, it’s important to consider the following factors:
Functionality: Ensure the hardware is suitable for the window size and weight. Heavy sashes require robust pulleys and sash lifts.
Aesthetic: Match the hardware finish to your interior design and window style. Period properties benefit from traditional finishes like polished brass, while contemporary homes might prefer chrome or nickel.
Durability: Opt for things like corrosion resistant materials like stainless steel or chrome if the windows are exposed to moisture or salt air.
Security: Choose fasteners and locks that provide additional security, especially for ground-floor or accessible windows.
Early Beginnings in 17th Century England: The sash window is believed to have been invented in England in the mid-17th century, although its exact origins are debated. Some attribute it to architect Robert Hooke, who incorporated this window style in many of his designs, while others believe it was introduced by Dutch engineers.
Popularity During the Georgian and Victorian Periods: Sash windows gained widespread popularity in the Georgian period (1714–1837), becoming a defining feature of this architectural style. The use of small and evenly spaced panes, held together with glazing bars allowed for better light distribution and ventilation of homes.
Victorian Period Innovations: The Victorian era saw significant innovations in sash window hardware, including the introduction of spring balances as an alternative to weights and pulleys. This allowed for narrower frames and larger glass panes, catering to the Victorians love of light filled interiors.
Edwardian Simplification: In the early 20th century, the Edwardian period brought a simplification of sash window hardware designs. While the frames and sashes themselves became more elaborate, hardware such as sash lifts and fasteners were streamlined and often hidden to achieve a cleaner look.
Industrial Revolution and Mass Production: The Industrial Revolution enabled the mass production of sash window hardware, making it more affordable and widely available. This period also saw the rise of decorative hardware designs, including embossed and engraved details, which became status symbols in many houses.
The Decline and Revival of Sash Windows: By the mid 20th century, sash windows had largely fallen out of favour due to the rise of modernist architecture and new materials like aluminium and PVC. However, they have experienced a revival in recent decades as homeowners and restorers seek to preserve the historical integrity of period properties.
Influence on Architectural Styles Worldwide: The sash window, along with its distinctive hardware, spread from the UK to other parts of the world, influencing colonial architecture in North America, Australia, and beyond. Many heritage buildings in these regions still retain their original sash windows and hardware, showcasing the lasting legacy of this design.
The Invention of the Sash Window Pulley System: The use of counterweights and pulleys in sash windows dates back to the 17th century. This ingenious mechanism, which allows sashes to be easily lifted and held in place, revolutionised window design and made the sash window a popular choice all across Europe.
The “London Sash” vs “The Yorkshire Sash”: While most sash windows are vertically sliding, there is also a horizontally sliding version known as the “Yorkshire sash.” This variation was popular in rural areas and cottages, where the window space was broader than it was tall.
Victorian Hardware Innovations: During the Victorian era, advancements in metallurgy allowed for the mass production of more intricate and durable hardware. This period saw the development of elaborate sash fasteners and the widespread use of brass and bronze for a more decorative finish.
The Importance of Counterweights: Traditional sash windows use cast iron or lead weights hidden within the frame to balance the sashes. These weights are calibrated to match the weight of the sash perfectly, making the windows easy to open and close despite their often considerable size and weight.
The Evolution of Security: Early sash windows were quite easy to force open from the outside, so many 18th and 19th century properties included sash fasteners as one of the first “security” hardware innovations! Today’s locks and fasteners have evolved to offer much higher levels of security and can even include smart technology.
Not All Sash Window Hardware is Visible: Much of the hardware in a sash window, such as pulleys, weights, and cords, is hidden within the frame. This design maintains the window’s aesthetic while providing the necessary mechanical function.
Antique Hardware Fetches High Prices: Original sash window hardware, especially those made of high quality brass, bronze, or cast iron, can be highly valuable today. Antique sash lifts and fasteners from the Georgian and Victorian eras are often sought after by collectors and restorers.
The Rise of Brass in the Georgian Era: Brass became the preferred material for sash window hardware in the Georgian period due to its corrosion resistance and ease of casting. The warm golden tone of polished brass was also considered a mark of elegance and quality.
Glass Hardware for Light and Safety: In the early 20th century, the development of laminated glass made it possible to include larger glass panels in sash windows. This innovation led to the creation of special glass panelled handles and pulls that could withstand the immense heat and pressure.
