At Direct Trade Windows, our curved aluminium windows are precision-engineered to bring elegance and individuality to any architectural design. Whether you're working on a high-spec contemporary home or a commercial project with sweeping façades, our advanced profile bending techniques allow for smooth, accurate curves that perfectly match your vision. These windows are ideal for creating standout design features, offering the visual softness of a curved line with the strength and energy efficiency of modern aluminium construction.
Curved windows differ from arched windows by following a curved line in plan (as seen from above), making them perfect for panoramic designs and modern aesthetics. Each unit is manufactured in-house to meet your exact specifications, ensuring seamless integration with your space. Available in a range of finishes and glazing options, our curved windows provide both architectural impact and high performance in terms of thermal efficiency, acoustic insulation, and low maintenance durability.
