Our uPVC Sash windows boast an authentic ovolo shape to the frame, bead, sash, and sill, adding a touch of classic elegance to your home. Moreover, we offer you the flexibility to further customise your windows to match your unique style or the architectural era of your property.

Options include the addition of Georgian bars for a touch of traditional charm, sash horns for a vintage aesthetic, weather bars for additional protection from the elements, and a deep bottom rail, which is particularly suited to period properties.

Furthermore, we utilise flush gaskets to emulate the look of traditional glazing, enhancing the authentic appeal of our uPVC Sash windows. With these customisation options, you have the opportunity to create a window that is truly tailored to your home and personal taste.



A spirally wound balance mechanism is ingeniously nestled within the frame of our uPVC Sash windows. This intricate system counterbalances the sash, facilitating a smooth and effortless movement whenever the window is opened or closed.

Moreover, the window features an internal glazing bead, which enhances the security of the window significantly compared to those with external beading. This design element ensures that the window glass cannot be removed from outside, adding an extra layer of protection.


Thermally Efficient

Our uPVC Sash window systems are thoughtfully designed to attain a Window Energy Rating of Band ‘A’. A-rated windows can have a substantial impact on reducing your energy bills. Beyond the economic advantage, they are also environmentally friendly, contributing towards a greener planet by minimizing energy waste. These windows even prevent drafts by incorporating pile seals to the sash and outer frame, further enhancing their energy efficiency.

As for noise reduction, double glazing is highly effective. The space between the two panes of glass in a double-glazed window acts as an insulator, not just for heat but also for noise. This feature can significantly reduce the level of noise that enters your home, making uPVC Sash windows an excellent choice if you live in a noisy neighborhood or near a busy road. It’s an added benefit that goes hand in hand with the energy efficiency and environmental advantages of our uPVC Sash windows.
