Roof lanterns

Urban Collection

The Urban Aluminium Roof Lantern Range is designed for modern spaces, with a sleek, minimalist profile that maximizes light flow. Made from high-quality aluminium with thermal breaks and energy-efficient glazing, these roof lanterns provide a stylish, low-maintenance solution that enhances both the aesthetics and thermal performance of your home.

Keswick

The Keswick aluminium roof lantern is designed to make a striking architectural feature of longer, narrower roof openings. Measuring 3000mm × 1000mm (finished external kerb), its elongated four-pane configuration provides an impressive three-metre span of glazing, making it particularly suitable for contemporary kitchen extensions, side-return extensions and spaces with a long, rectangular roof layout.

Part of our Urban Collection, the Keswick features slim 40mm aluminium framing and clean, minimalist detailing that emphasise its elegant proportions. The extended glazed area provides an opportunity to introduce natural light along the length of a room, while thermally broken aluminium profiles and energy-efficient double glazing help limit heat loss.

Available in a choice of frame colours and glazing options, the Keswick combines contemporary architectural styling with durable, low-maintenance construction. Supplied in kit form for assembly on site, it offers a distinctive solution for modern extensions where length, natural light and understated design are key considerations.
