At Direct Trade Windows, our arched and curved aluminium windows are crafted with precision to bring timeless elegance and custom design to a wide range of architectural projects. Using advanced profile bending techniques, we manufacture window frames that integrate seamlessly with both traditional and modern structures. Whether it’s a true arch for a Georgian property, a gothic style for a period restoration, or a smooth curve for a contemporary new build, our windows deliver a perfect balance of form and function.

Arched windows add classical charm with their elevation curves—semicircular, elliptical, or gothic in design—ideal for traditional or listed buildings. In contrast, curved windows feature a curvature on plan (seen from above), creating panoramic views and a sleek architectural aesthetic. Each style offers its own design benefit and our in-house expertise ensures your windows are engineered to suit the specific requirements of each project.

Available in a range of styles and shapes—including circular, elliptical, true arches, and more—our bespoke shaped windows are built for accuracy, energy performance, and long-term durability. Whether you’re a trade professional working on a period restoration or a modern designer seeking striking visual elements, our shaped windows provide the flexibility, performance, and quality you need.

    What Should You Know About Arched and Curved Windows?

    What materials are available for your arched and curved windows?

    Our arched and curved windows are crafted from high-quality aluminium. This ensures exceptional durability, minimal maintenance, and sleek profiles. The aluminium can be finished in a variety of colours and styles, allowing for customisation to match any architectural design, from traditional to contemporary.

    Can your arched and curved windows be customised to fit specific designs?

    Yes, we offer bespoke solutions for all arched and curved window designs. Using advanced profile bending techniques, we can create windows that fit perfectly with your specified dimensions and styles, including gothic arches, perfect circles, and custom curved shapes.

    Are your arched and curved windows suitable for period property renovations?

    Absolutely. Our windows are ideal for sympathetic restorations of period properties. We replicate the classic styles of Victorian and Edwardian arched sash windows, ensuring a harmonious blend with traditional architecture while providing modern energy efficiency and security.

    How do your arched and curved windows perform in terms of energy efficiency?

    Our windows are designed with energy efficiency in mind. The aluminium frames incorporate thermal breaks, and our glazing options offer superior insulation. This combination helps reduce heat loss and can contribute to lower energy bills, making our windows both eco-friendly and cost-effective.

    What is the typical lead time for ordering arched and curved windows?

    The lead time for our arched and curved windows varies depending on the complexity of the design and current demand. Typically, we aim for a stable turnaround time of 6-8 weeks from order confirmation to delivery, ensuring high-quality craftsmanship and on-time completion.
