Sliding sash windows have been around for centuries since the 16th century to be exact. These beloved windows are still developed today thanks to their remarkable blend of traditional design and modern efficiency. The stylish power of these windows means that their addition alone can make almost any home gain a period aesthetic.

What are sliding sash windows?

At Quickslide, we offer a wide variety of our sliding sash windows. But what are they? Although sliding sash windows have been popular for centuries, few people know what “sliding sash window” means. Sometimes referred to as just sash windows, they’re categorised by the two-window sash design, with one sash sitting just in front of the other with vertical grooves allowing it to slide up and down. The up-and-down motion was traditionally supported further by weighted cords and pulleys usually obscured within the frame. Nowadays, modern windows are fitted with innovative balances to allow the sliding feature.

So, now you know what we mean by sliding sash windows, but what kinds are there?

Single-hung sliding sash and double-hung sliding sash windows

A sash window that only allows its bottom sash to be lifted, with its upper half fixed, is referred to as a single-hung sliding sash window. Meanwhile, a double-hung sliding sash window has sashes that are both able to slide open.

What materials can they be made from?


uPVC has been widely accessible on the market for quite some time, and its popularity has remained strong for almost all of its career as a window crafting material. One of the key benefits of this choice is that it can be covered in an almost endless variety of woodgrains, finishes, and colours, making it the most versatile material compared to its peers.

It’s also very affordable, whilst not having a reduction in quality. Just like aluminium, it has a low maintenance requirement with only an occasional wipe down with a warm soapy sponge to keep the material looking fresh and factory new.

uPVC is lightweight, allowing it to rely on less heavy window components. A light frame construction allows a smoother sliding and tilting experience, whether you’re opening or closing the window.


The most modern material on the market, aluminium can provide a sleek new look to any window design. While aluminium sash windows are available on the wider double-glazing market, it’s not something we offer. We specialise in traditional looking sash windows and feel that the properties of aluminium are a tad too modern-looking. However, we do offer a beautiful range of aluminium casement windows instead. Check out the range right here on website.


Traditional, authentic, and beautiful. Timber has been used to build sliding sash windows for centuries, and some would argue it’s still the original sash window material! However, timber requires much more maintenance than other more modern materials and it’s got a reputation of rotting if not cared for properly. With that being said, no one can deny its gorgeous historical look.

Quickslide has built its reputation on developing sash windows of uPVC that look as close to the original timber version. With our wood effect upgrade and historical features, we’re proud to offer a top of the class timber alternative window solution.
