Rather than try and mess around with an old classic, we have improved sliding sash windows significantly and brought them up to date with a 21st Century twist. This window really does have it all as not only can it slide upwards and downwards, but it can also tilt inwardly, meaning that cleaning of the windows can be done in half the time you would normally expect.
Planet can promise customers that sliding sash windows will work beautifully in combination with any other style of window you may already have installed in your home.

UPVC Sliding Sash Windows
The sliding sash window, first introduced in the 16th century, remains a top choice thanks to its timeless vertical-opening design. Featuring two sashes, with one positioned slightly in front of the other, it glides effortlessly up and down, perfect for enhancing the charm of period properties. Our Extreme sliding sash windows stay true to this classic look while incorporating modern innovations.
Designed with energy-efficient glass as standard, these windows are built to perform and endure well beyond their warranty. Whether you prefer double or triple glazing, our Extreme sliding sash windows can be tailored to deliver enhanced security and superior comfort.
A colour range that’s rich, varied, and full of possibilities...
When you think of sliding sash windows, white is often the first colour that comes to mind. However, at Planet, we offer a diverse selection of alternative shades to suit every taste. Each finish is carefully crafted to highlight the exceptional workmanship behind our windows while ensuring they remain low maintenance.
For a charming, countryside feel, opt for our ever-popular Chartwell Green. Prefer something bolder? Matt Black makes a striking statement. And if you can’t decide on just one, why not mix things up with a dual-colour finish, allowing you to have contrasting hues on the interior and exterior of the frame?
We’ll give you a hand deciding on the perfect handles...
When choosing window accessories like handles, the goal is to enhance the look of your sliding sash windows and make sure they fit the style of your home.
Security is also taken care of, as each window handle includes high-security features. A seasoned design expert will guide you through all your handle options, at a time and place that’s convenient to you.
Sash windows featuring authentic hardware...
It could take some time for you to decide how to furnish your sash windows as there are a string of potential hardware accessories available for the range. There are so many variations of handles, hinges, and pulls, and they all offer something different, both in terms of their appearance and functionality.
