Our uPVC sash windows combine the timeless charm and aesthetic of traditional timber with the advantages of contemporary manufacturing methods and materials. The result is a collection of stylish, enduring sash windows that enhance the security and warmth of your home.
These windows have been meticulously designed and constructed with key features to accomplish two main goals: providing the maintenance-free performance of a modern window, while preserving the character and charm of traditional period sash windows.
Seamless construction
It’s not just what you add to a window to make it authentic, what you take away is just as important. Standard uPVC sash windows have caps and covers that create tell-tale seams and shadow lines. We’ve pioneered the development of seamless technology that removes these lines, leaving a smooth, continuous surface—just like timber.
Mechanical joints
All the joints on Ultimate Rose are genuine joinery-style mechanical butt joints – a fundamental part of a traditional sash window. Nothing is welded. And the orientation of the joints is exactly the same as timber—vertical on the sashes, horizontal on the frame.
35mm midrail
Look at an original sash window and you’ll notice how slim the timbers are. Our uPVC windows can match these slim sightlines throughout, but nowhere more obvious than the midrail. We use a special ultra-slim midrail that’s only 35mm deep. It’s the slimmest on the market; a full 10% slimmer than the nearest rival.
Paint-effect finish
Typically uPVC windows have either a smooth glossy finish or an applied woodgrain texture. But neither of these accurately match the effect of paint on timber. That’s why we also offer our unique chalk textured finish. It removes the gloss of standard uPVC and adds texture without adding the false woodgrain that isn’t there in real life.
uPVC sash windows are an excellent choice for homeowners due to their energy efficiency and low maintenance. With superior insulation properties, these windows help keep your home warm in winter and cool in summer, potentially lowering energy bills. uPVC windows also come with double or triple glazing options, enhancing their energy efficiency further. Additionally, they are durable and resistant to weathering, unlike traditional wooden sash windows, which can rot or warp over time. Cleaning and maintenance are minimal, as they require only occasional wiping with soapy water to keep them looking fresh.
Another significant advantage of uPVC sash windows is their cost-effectiveness. They are generally more affordable than timber or aluminium alternatives, offering excellent value for money. Their long lifespan means that the initial investment is well worth it, as replacements or repairs are rarely necessary. Furthermore, modern uPVC sash windows can replicate the traditional look of wooden sash windows, making them suitable for period properties or those in conservation areas. A wide variety of colours and finishes are available, allowing you to customise the windows to suit your home’s style.
Security and noise reduction are also key benefits of uPVC sash windows. They are often fitted with multi-point locking systems, making them more secure against break-ins, while additional safety features like child locks or restrictors can provide peace of mind. uPVC sash windows also offer good sound insulation, particularly when paired with double glazing, reducing outside noise. Moreover, they are weather-resistant and can withstand various conditions, ensuring they stay in excellent condition for many years. The recyclable nature of uPVC adds to its appeal, making it a more environmentally friendly option.
