Our uPVC Flush Casement Windows are part of the Residence Collection – a premium mock timber uPVC window brand.

Safe & Secure

Safe & Secure

The flush sash windows that we install are created using modern uPVC, a durable material capable of withstanding harsh weather conditions without splitting, cracking, or warping. The tight weather seals can keep out cold draughts and winds, ensuring your home can stay safe and dry. 

Each of our uPVC flush sash windows comes with multi point locking systems as standard. The locks are designed to resist tampering, and they can help secure your home against modern intrusion techniques. All the hardware choices are built robust and don’t sacrifice any safety while providing a gorgeous finishing touch to your home’s windows.

Energy Efficient

Energy Efficient

Our flush sash windows by Deceuninck can reach an impressive A+ energy rating with incredibly low U-values. The 9 hidden chambers within the frames help to retain heat, and with your choice of double or triple glazing, you can stay warm and comfortable all year round.

The thick glazing traps heat between the panes, preventing it from escaping, which can help your home stay warmer for longer. By relying less on your central heating systems, you could even benefit from a reduced energy bill and a lower carbon footprint.

Slim Sightlines

Slim Sightlines

The uPVC profiles and frames can be made much slimmer than other materials, allowing for larger panes of bespoke energy efficient glazing. Having a sleeker profile can offer gorgeous views and sightlines, flooding your home with more natural light. We can also integrate these flush sash windows into bay and bow windows 

Additionally, uPVC is an impressively lightweight material despite its innate strength, making it easy to open and close your flush sash windows. This smooth performance can last for years with minimal upkeep, only requiring an occasional cleaning with a wet cloth or sponge.



Our flush sash windows can be customised in a variety of ways to suit your property! Choose between double or triple glazing to suit your thermal needs, and pick from a range of additional period hardware such as bars, handles, and hinges. The Heritage colour range is also available for our flush sash windows, letting you get the perfect finishing touch to make your flush sash windows blend in seamlessly with your home’s existing aesthetic. 

Every colour is designed to resist fading and can continue to help your home look its best for years without cracking from heavy rains or intense heat. From No.10 Black to English Oak and Cotswold Green, any home can benefit from these sleek and high performing windows.
