What Are Sash Windows?

Sash windows, often seen gracing traditional buildings, are charming windows that open vertically and add character to any home.

They feature 2 framed window sashes, set one behind the other, and are often known as “sliding-sash windows.”

The sashes glide up and down in their frames, which are cleverly designed using vertical grooves to ensure smooth, frictionless movement. The movement is gracefully achieved through the use of counterbalances, which are weights connected by cords & pulleys, ingeniously concealed inside the frame.

In some instances, these are displayed inside the window, though that’s a lot less common.

Unlike hinged windows, sliding-sash windows don’t swing outwards, though modern versions may tilt inward for easy cleaning.

Glazing bars play a significant role in sash windows, contributing to that quintessentially English look found in Edwardian and Georgian homes. These are the horizontal & vertical wooden strips that hold together smaller glass panes, creating a larger window. This design was born out of necessity in earlier times when glassmaking was rudimentary, and only small glass panes were feasible.

Today, though we can produce much larger glass panes, the charm of traditional windows is often desired, especially in heritage properties. Modern sash windows replicate this classic look with single large panes overlaid with window bars to mimic the historical style. Innovations like ultra-thin double glazing, enhance this illusion, making the windows appear as if they’re made from just a single glazed unit.

What Are The Different Types Of Sash Windows?

Sash windows come in various styles, each reflecting the architectural trends of different historical periods. The type you choose should complement your home’s design and the era it represents or emulates.

There are quite a few different types of sash window, here are 3 of the most common ones:

Georgian-Sash Windows

Georgian-Sash Windows

Half Georgian-Sash Windows

Similar to Georgian sash windows, a half Georgian sash window typically features a 6/1 pane arrangement.

Victorian-Sash Windows

Victorian-Sash Windows

Victorian sash windows typically showcase a 2/2 design, where each window unit comprises 2 large panes, divided by a vertical glazing bar.

This style reflects the Victorian penchant for simpler, yet elegant designs.

Edwardian-Sash Windows

Edwardian sash windows often feature a 6/2 design. Reflecting the era’s emphasis on spaciousness and light, these windows usually have larger lower units made from 2 panes of glass, allowing more light to enter.

The upper sashes follow the Georgian style with 6 panes.
