Stylish bow windows for homes. Available in uPVC, aluminium and timber — expertly installed to bring in light and enhance your exterior.
We supply and install beautifully curved bow window systems from premium brands such as Internorm, Drutex, Reynaers, and Schüco.
Unlike angular bay windows, bow windows form a gentle arc using 3 to 6 panels, creating a panoramic feel while maintaining a timeless, traditional elegance.
Bow windows enhance both exterior façade and interior space, flooding rooms with natural light and creating a sense of openness. Whether you’re modernising a period home or adding character to a new build, these windows combine old-world charm with cutting-edge insulation and security features.
Choose Internorm for Passive House-certified timber-aluminium systems, Drutex for uPVC value and thermal performance, and Reynaers or Schüco for sleek aluminium frames suited to bespoke curves and contemporary design.
A bow window is a curved projection built from four or more window units joined together to create a gentle arch shape. Each pane can be fixed or operable, allowing natural light to pour in from multiple angles.
The curvature of a bow window offers a softer, more graceful appearance than a traditional bay window and can span a wider opening.
We combine architectural knowledge with technical expertise to help homeowners, developers, and designers integrate bow windows beautifully and effectively. Our FENSA-Certified team ensures structural support, airtight fitting, and elegant finishing on every installation.
We supply only the highest quality systems from trusted European manufacturers and tailor each configuration to your style, structure, and energy goals.
