Sliding sash windows have endured as a popular choice for centuries – observing their sophisticated design, it’s clear to see why. They’re assembled to exploit one or more moveable panels (known as sashes), capable of maneuvering to encourage greater airflow in the warmer seasons. Sash windows enjoy an elegant, traditional aesthetic, perfect for period homes or classic-styled decors.

We create sliding sash windows which exploit the impressive qualities of our uPVC whilst replicating the beauty of traditional timber. You’ll be able to enjoy the durability and maintenance benefits of uPVC, whilst marveling at the graceful timber-like appearance, enhanced by our elegant woodgrain finishes. Talk about best of both worlds!

Classic look, modern innovation…

At Mr Window, our sliding sash windows are designed to replicate refined, classical box-sash windows. Our sash windows marry the modern, technological feats of uPVC with the elegant, traditional aesthetic of the classical sash window, creating a unique blend possessing the benefits of both. Furthermore, most local councils will accept our products for Conservation Areas.

Our uPVC is indistinguishable from timber, but easily maintained – our design includes a tilt function, allowing the sashes to tilt inwards for simple, straightforward cleaning. Furthermore, our double glazed sash windows are ‘A energy rated’ as standard, ensuring heat retention, noise reduction and protection from drafts and gusts in the colder seasons. Our sash windows are bespoke, made-to-measure, designed exclusively for you and your home. We offer a vast array of colours, too, including woodgrain finishes to perfectly mimic timber without the difficult maintenance issues wood can entail. Our sliding sash windows come with a 10 Year Guarantee – a testimony to our craftsmanship, honesty and confidence in our products.

Frequently Asked Questions

Why is it called a sliding sash window?

The sliding sash window is made up of several movable panels, called sashes, which ‘slide’. These sashes fit together, holding the glass panes in place, which are separated by astragal bars.

Are sliding sash windows secure?

Yes, we ensure all our windows are secure to keep you and your household safe. We reinforce the window with galvanized steel and utilise toughened, A rated glass. In addition, all of our products are Secured by Design accredited, to ensure your safety.

How do sliding sash windows work?

The window is made of several movable panels, which are called sashes. The sliding sash is operated using a pulley and weight mechanism inside the window, which allows you to open and close the window. When the sash opens, the weight of this is balanced with a weight inside the window frame. This allows the window to stay open.

Do sliding sash windows open both ways?

Yes, our sliding sash windows are capable of opening from the top and the bottom, to ensure flexibility and greater airflow in the hotter seasons. However, if you would prefer to have a fixed pane, we can create this too – all our windows are bespoke and made to meet your specifications

How do you clean sliding sash windows?

As our sliding sash windows open from both the top and the bottom, you will be able to reach hard-to-clean spots. Furthermore, they also include a tilt function, allowing the sashes to tilt inwards for simple cleaning. We would recommend a glass cleaner coupled with a microfibre cloth.
