What are uPVC sliding sash windows?

double-glazed uPVC sash window diagram

Chances are that you've seen uPVC sash windows before, whether you knew it at the time or not. Sash windows are easily recognisable by their characteristic sliding pane mechanism. 

But how do uPVC sash windows work? Well, instead of opening inwards or outwards like casement windows and tilt-and-turn windows, traditional uPVC sash windows are made up of two sashes that usually slide up and down on vertical grooves. With one window sash in front and one behind they slide to reveal a gap when opened.

The internal sliding mechanism of sash windows makes them an ideal choice for homes located in city centres or looking for easy-to-clean options. Because they do not open on a hinge outward, they won't obstruct a pathway or road. This opening mechanism is also perfect for allowing ample air into a property, making for a comfortable environment with proper ventilation.

While uPVC is a popular material for sash windows, aluminium and wooden sash windows are also available. But if you're looking for the most affordable option, then sticking with uPVC is your best option.

Double glazed uPVC sash windows options

When it comes to installing new or replacement sash windows, opting for double-glazed windows is a common practice. Double-glazed sash windows offer the elegance of traditional sash windows with added thermal efficiency. They use two panes of glass to insulate the home, reducing energy bills and external noise while keeping the home warmer in winter and cooler in summer.

Typically, the glazed area of a sash window consists of smaller panes that are held together by glazing bars. The number of panes used in a sash window can vary depending on the era in which it was made. 

We'll explain how sash windows have changed over time through the Georgian and Victorian eras and key period properties of each window option.

Vertical sliding sash windows

Vertical sliding sash windows

You will most commonly see sash windows that open vertically. However, don't be surprised if you see a horizontal sash window, also known as a Yorkshire sash window. They operate very similarly to vertical sliding sash windows, but instead you get to enjoy ventilation from left and right.

With vertical sliding sash windows, it's not uncommon to see double-hung sash windows with two operating sashes that slide. This allows for ventilation on the top, bottom, or both. However, you can also opt for single-hung windows which have only one sash that slides. 

Georgian sash windows

Georgian sash windows

Georgian sash windows are most characteristically known for having their 6-panes-over-6 panes design. These windows are among the oldest type of windows that are still commonly found in the UK. 

While today it is possible to have large sashes with a single glass pane, during the Georgian era it was only possible to make small single glass panes. That's how the 6-over-6 design came to be where individual small glass panes were kept in places through glazing bars.

Victorian sash windows

By the time the Victorian era came, making larger glass panes was possible and more cost-effective. Victorian sash windows are defined by having a 2-pane-over-2-pane design. This modern design, with fewer glazing bars, allowed for more natural light to enter the room.
