Types of sash windows

Depending on the era in which your home was built, it may have certain types of sash windows. Likewise, different styles were popular during specific periods. In this article, we’ll explore these variations so that you can identify the sash windows in your own period home.

To ascertain what style of sash window you have, look at the following features: glazing bars, the configuration of glazing bars, and the size of the window.

By identifying these key characteristics, you will be able to understand better the type of repairs or restoration work your windows may need.

The different types of sash windows

The sash windows in your home were likely influenced by the period it was built and which style of sashes was most popular then.

There are many different types of sash window designs, each with its own unique features:

Georgian sash window – these windows featured six over six glass panes and were popularised in the Georgian era (1714-1830).

Victorian sash window – These sash windows have a two-over-two grid design and were popular between (1837 – 1901).

Edwardian sash window – The Edwardian style goes back to the Georgian formation of the window panes, but instead of six over six, this period saw six over two designs become increasingly popular at the beginning of the 20th century (1901 – 1910).

Did you know that there are sash windows called ‘Yorkshire Sash’ windows?

These horizontally opening sash windows originated in Yorkshire and have become increasingly popular.

Sash window styles

Over the years, there have been different sash window styles added to the above types, but these are often modern-day designs that are not in keeping with period homes.

We would recommend keeping your sash windows in the style that they are in now unless they have been changed to a modern design and you’re looking into reverting them to the original sash windows.

Sash window styles say a lot about a property. In fact, many period properties can be dated just by their windows alone.

There are also restrictions on listed buildings and the window styles that they can have. Just because a window is classed as a ‘sash’ doesn’t mean that it can be fitted into a listed building.

If you’re concerned that the windows in your listed property are no longer performing as they should, we do offer complete restoration services for all types of sash windows.

Scott James’ team can repair rotten wood in the window frame, replace any broken panes of glass and draught-proof the windows once more. We also offer sash window mechanism restoration services too.

Our team can also fit double glazing in any style of the sash window, replacing the single pane of glass with ultra-thin double glazing.

Traditional sash window mechanism

Most sash windows have a traditional mechanism – this is a counterweight attached to a pulley system.

As you operate the window, the counterweight moves up and down in the window’s frame for a smooth and easy operation.

If the counterweight becomes unattached or stuck inside the frame, it may not be easy to move the sash.

In this instance, the sash mechanism will require repair.

Traditional mechanisms use cords, but they’re are also some windows that utilize chains.

Spiral balance sash window mechanism

You may have heard of spiral-balanced sash window mechanisms. These are a modern version of the traditional mechanism, which allows for a lower-profile frame.

The spiral balance is smaller than traditional weights in all dimensions, which allows for a smaller frame. This means the box where the weight is located can be reduced in size.

The spiral-balance mechanism is designed to be used with modern new sash windows.

Window frame types

There are many different window frame designs for sash windows and casement windows, but the materials used have often been the same.

Most traditional sash windows use wooden frames because they are extremely durable and very good sound and thermal insulators.

Some older sash windows did use metal frames to hole the pane of glass, but these are very rare nowadays. 

Other more modern sash windows use uPVC or aluminium for the window frames. These are low-maintenance options but can really ruin the charm and style of an older property.

UPVC is the cheapest option for most window frames, which is why most modern homes choose this option. If your home is listed, uPVC likely won’t be an option for you. Even if it is, having these window frames installed into a beautiful period home can dramatically change the appearance of your home forever.
