Aluminium Bespoke Windows in Kent

We can create bespoke aluminium windows in Kent designed to meet your exact specifications. Whether you want an unusually shaped window or an oversized modern window, we have the expertise to bring your design to life. They are made using slimline aluminium frames which allow a wealth of natural light to enter the rooms, while adding a contemporary aesthetic to your home. You can choose from over 150+ smooth RAL colours. For the ultimate customisation, dual colour options are available. To add the unique finishing touches, you can choose to include any of our window furniture pieces and decorative glazing. For an original aluminium window solution, choose our slimline bespoke style.

Aluminium is an inherently strong material, making it an excellent choice for constructing windows. This means it provides outstanding levels of durability and home security and won’t rust or corrode for at least 45 years. This is thanks to a high-performance finishing coating, which also stops the frame from fading. Not only do they look great, but aluminium excels in its thermal performance. With thermally broken frames and when paired with either our A+ energy rated double glazing or comfort glass, you’ll benefit from a state-of-the-art window solution.

    Our bespoke aluminium windows are designed to offer top-notch performance with an A+ energy rating, ensuring that draughts are kept at bay and your heating bills remain low. With thermally broken barriers, these windows effectively retain heat within your rooms and keep the cold outside. We provide high-performance and sustainable EcoMAX double glazing, as well as Comfort Glass, with both resulting in remarkably low U-values and impressive noise reduction capabilities.
    Aluminium is an ideal choice for challenging environments, including coastal areas, as it is resistant to rust and corrosion. With an exceptional lifespan of at least 45 years, these windows require minimal maintenance and will maintain their pristine appearance with just a simple wipe clean.
    Regardless of the shape or style you choose, our aluminium frames are designed to provide utmost security for your home thanks to multi-point locking mechanismsisms, which securely bolt the frame to the windowpane, ensuring enhanced protection. For additional peace of mind, we offer the option to incorporate further security features into your bespoke design.
