Sash Windows Explained

Sash Windows Explained

Windows can offer more than just practicality; when dressed correctly, a window can become a stunning decorative feature in your home, so it’s important not to overlook them during your design project.

A classic style which never goes out of fashion is the sash window which is once again rising in popularity.

What are Sash Windows?

Sash windows are made from two frames (also known as “sashes”) with one positioned slightly in front of the other. Each sash can slide vertically in parallel to the other, via a series of rods, weights, and pulleys alongside counterbalances which allow smooth movement.

Sash windows are commonly found in period properties and stately homes, particularly those from the Georgian, Victorian, and Edwardian eras. However, sash windows are seeing a revival as many new builds incorporate them into their design thanks to their practicality and curb appeal.

Because the upper and lower sashes can be opened separately, sash windows offer wonderful ventilation without having to be propped fully open (this is especially important for homes with young children or pets).

When you have windows that are so beautiful, it’s important to choose accents which will enhance them.

What sash furniture do I need?

Excluding the internal mechanisms, there are two main choices you need to make when selecting hardware for your sash windows: the fasteners and the handles.


Sash Fasteners

Sash fasteners are used to add security to a property. They lock the window by holding the two sashes in place, preventing them from sliding apart. We currently offer four types of fasteners: Quadrant, Brighton, Fitch and Hook fasteners.

Fitch, Hook and Quadrant fasteners all work in a very similar way. Each fastener is made up of two pieces, one fitted to each window sash. One piece is the receiver and the other is the arm which swings into the joint to lock the window and keep the sash in place.

Conversely, Brighton fasteners have a threaded arm which lifts over the join and is secured by screwing a dome-shaped nut into place. This option is particularly useful for looser fitting windows.

Our Fitch fasteners have a minimalist appearance whereas our Hook fasteners are available in a decorative Beehive, Prestbury and Ball design. Our Quadrant and Brighton fasteners are available in a variety of designs including Brompton, Beehive, Mushroom & Prestbury to match our existing collections of ironmongery.

We’ve also recently expanded our collection of sash furniture to include narrow Brighton fasteners in the same designs which are ideal for use on UPVC sliding sash windows.


Sash Handles

There are three main types of handles used with sash windows: eye lifts, sash lifts, and pull handles.

Eye lifts consist of a solid ring on a backplate which screws onto the frame of either the top or bottom sash. If fitted to the bottom sash, the eye lifts can be operated with a finger but if fitted to the top of a high window, a pole hook may be required to open/close the sash.


Sash lifts are like small, rounded hooks that sit on the lower sash and are used to lift the window open. These are typically fitted in pairs with one on either side of the window, though a single sash lift may be used in the middle of a small, narrow window.

Pull handles are long, slim handles which can be fitted horizontally to both the top and bottom sashes as an alternative to sash lifts. These are commonly fitted as pairs with one on the left hand side and another on the right to ensure the window opens smoothly.


Choosing a Sash Hardware Finish

Our sash window hardware is available in an extensive array of finishes, enabling you to coordinate your windows with your existing ironmongery for a cohesive look.

Aged Brass and Aged Bronze are a fantastic choice for period properties and those looking to stay true to tradition. Alternatively, opt for Polished Chrome or Satin Chrome to bring a contemporary twist to your windows.




Sash windows are a statement feature in any property so it’s important to fit them with quality hardware that will accentuate their frame.
