RLM VERTICAL SLIDING SASH WINDOWS

Vertical Sliding Sash Windows

Our UPVC sliding sash windows carry all the beauty of a traditional designed window, coupled with all the benefits of modern materials that enable us to offer a low maintenance UPVC window that doesn’t compromise on aesthetics.

From near-invisible joints, the elegance of the run-through sash horn to the curvy ovolo frame shape, these are just a handful of the many clever details that work together to create the most graceful and advanced sash window on the market.

With the increase of sliding sash windows being specified in premium developments, new design options and a bespoke colour-bonding service have been introduced, providing you with a plethora of choice to create the perfect timber alternative solution that doesn’t break the bank.

Why Vertical Sliding Sash

With our Vertical Sliding Sash Windows, you can respect the traditions, admire the woodworker’s art, and enjoy modern advances that can make your home warm and secure. From a terraced house to a stately home, our sash windows can help ensure that your property retains its character and charm. You can choose from a wide range of styles, features, and hardware options to complement your home. Visit our showroom or contact us for a free quote.
