Sash Windows: The Design Classic That Keeps on Giving

Sash windows are a design classic. Their distinctive style adds undisputed character to a property, that will stand the test of time. These traditional period home features also have a practical side to them. From letting in light and creating ventilation to making a home more energy efficient and being easy to clean.

But there’s more. If you have a heritage house, then having sash windows, which are authentic to the era, can also add value to your home. But this depends on the quality of the materials and workmanship, and how well they’ve been looked after. Let’s explore this in more detail.

It’s all in the detail

Sash windows have been used in British architecture since the 17th century ­– evolving over time to include design touches which have come to represent individual eras. The Georgians particularly favoured the ‘six-over-six’ design of the double-hung sash window and introduced smaller panes separated by a number of glazing bars. In contrast, the Victorians preferred one large pane of glass in each sash, while during Edwardian times, the top sash featured multiple panes contrasted with a single pane of glass on the lower sash. We take a look at the different types and styles here.


Whether your home is traditional or a new build, sash windows can be customised to fit the aesthetic. If your original period windows are beyond repair, and you require new ones making, specialists will ensure that all the authentic heritage details are mirrored. And if you have a modern home, you can have sash windows made in a simpler and cleaner style, to suit a contemporary property.
