Our uPVC sliding sash windows have received another upgrade! If you’re looking for sliding sash windows that can maintain the traditional sash window appearance for your home, then look no further than our authentic range.

Authentic uPVC Sash Windows

The new slim mid-rail is one of many classic characteristics that these sliding sash windows can feature to make them the perfect replacement for traditional timber windows. They can bridge the gap between contemporary efficiency, security, low maintenance and heritage aesthetics thanks to their classic design, thanks to their classic design.

As the latest innovation in uPVC sliding sash manufacturing, this new midrail is more than 10mm slimmer than its standard counterpart, to match the frame proportions found on traditional Victorian windows. The new 37mm midrail allows the sharp-eyed homeowner even more control over their property appearance. Another benefit to a sleeker midrail is that it allows for a slightly larger glazing area, leading to better sightlines with enhanced views of the outdoors and greater natural light infusion.

Beyond the slim midrail, our sliding sash windows can come in Edwardian, Victorian, and Georgian styles to best fit any period property. To further enhance the traditional look, choose one of our many woodgrains, such as grained white to mimic white timber or agate grey for a contemporary touch. The available accessories, including run-through horns, sash horns, deep bottom rail, astragal bars, and the ovolo-shaped weather bar are all accessories that further add to the aesthetic, making it virtually impossible to tell our sash windows apart from real timber.

Sash Windows for Conservation Areas

In conservation areas, maintaining the historical aesthetic of buildings is paramount. Sash windows are often considered characteristic features of buildings within these areas, and their design is subject to strict regulations to preserve the historic character. Many buildings in conservation areas were constructed during specific periods when a slim midrail was a common feature of the sash window style. A slim midrail may, therefore, be requested by the conservation officer, and adhering to such conditions is essential for obtaining planning permission.

Why uPVC Windows?

Upgrading to new sash windows in uPVC over older timber units can offer a whole host of benefits. First and foremost, these top sash windows come with energy efficient double glazing filled with argon gas, which allows for excellent thermal performance.

uPVC is a robust material that can withstand harsh weather conditions and consistent use without splintering or cracking, making it ideal for long lasting windows that pass the test of time. Unlike their timber counterparts, which can require consistent maintenance to keep clean and fresh looking, these alternatives only need an occasional cleaning with simple solutions and a clean cloth. Get all the impactful styles and colours, whether you’d like Victorian sash windows, Georgian sash windows, or any other of our timeless options with none of the hassle.
