In this article, we are going back in time to look at the history of sash windows, discovering the different designs from multiple eras.

What Is a Sash Window?

Before we take a trip into the past, it is important to first define what exactly makes a window a sash window. In simple terms, ‘sash window’ is the term given to windows that don’t open out on hinges. Sash windows operate by sliding horizontally or vertically. The majority of traditional sash windows slide up and down and feature two sashes within the frame.

The sashes are fitted inside vertical grooves, and weights attached to a cord inside the frame are used to counterbalance the glass. To open these sash windows, you simply push the sash up to your chosen location, and it will stay in place, thanks to the balanced weights inside the frame.

In traditional sash windows, each sash (piece of glazing) is made up of several smaller pieces of glass and held together with glazing bars. Sash windows from different eras have differing numbers of glass panes – we will talk more about this later!

Glazing technology and manufacturing methods have evolved over the years, and modern sash windows may have a similar aesthetic, but they often have a completely different structure and operating system.

A Brief History Of Sliding Sash Windows

While no one knows for certain, it is believed that sash windows first arrived on the architectural scene around the 17th century. Historians believe that sash windows were first used in France and Holland, before making their way across the continent to the UK.

One of the earliest examples of a fully functioning, sliding sash window was developed by master joiner Thamas Kinward, for Whitehall Palace in the 1600s. Due to their favour with royalty, sliding sash windows began to grow in popularity across 17th century Britain and throughout the Georgian era.

Georgian sash windows are the oldest windows still found in period properties today. In fact, if you live in a heritage home or conservation area, you may need to seek special permission before replacing these classic frames. As the decades went by, sash windows became the most popular window installation, and it wasn’t until the end of World War II that their sliding design was replaced with the hinged casement windows we know so well today.

Types Of Sash Windows

The original Georgian sash windows had a ‘6 over 6’ design. During this period, it was only possible to manufacture small glass panes, and each sash consisted of 6 glazing panels held together with glazing bars.

As time went on and technology advanced, manufacturers were able to create larger glazing panels, and the design of the sliding sash window changed. If you are unsure what era your sash windows are from, counting the number of glass panes is an effective way to find out.

Here are the different types of sash windows and their common design features:

• Georgian sash windows – The original sash windows feature a ‘6 over 6’ sash design and include several glazing bars in the structure.

• Victorian sash windows – Often featuring larger glass panes, Victorian sash windows have a ‘2 over 2’ grid and are fitted with a run-through sash horn to support the extra weight.

• Queen Anne sash windows – Implementing a more decorative design, Queen Anne sash windows often included several small glass panes in the top sash, with just one or two large panes of glazing on the bottom. The frame designs were also more creative, featuring arches and other shapes.

• ‌Edwardian sash windows – The Edwardian era didn’t last for long, but it was an influential time in British architecture. Sash windows manufactured at this time were a blend of the Georgian and Victorian frames, featuring a ‘6 over 2’ design.

• Coupled sash windows – The coupled sash window design is an effective way to boost the amount of natural light inside a property. This type of sash window consists of two sliding sash profiles installed right next to each other. The grid pattern can vary, but coupled sash windows come in twos – as the name suggests.

Sash Windows Today

As you can see, sash windows have changed since the 17th century, and as glazing technology has evolved, so has the size and design of these timeless windows. There are period properties today that still have original sash windows installed with authentic timber frames, but the majority of homeowners opt for a more modern installation.

Unfortunately, windows that are hundreds of years old are not able to offer the best thermal performance and security desired by homeowners today. Contemporary sash windows are designed to offer 21st century homeowners the charming traditional sash design with all the benefits of modern materials and manufacturing methods.

Made from high grade uPVC, the sash windows we install here at Sashes of Surrey have an authentic appearance but offer high levels of durability, security, weather resistance and longevity.

Sash windows today can be customised to look exactly like authentic timber frames but are installed with advanced double glazing and insulated frames. Homeowners can also choose to accessorise their sliding sash windows with authentic decorative features and choose to colour the uPVC frames in almost any shade.
