Atlas Aluminium Square Premium Roof Lantern

Atlas Contemporary Aluminium Roof Lantern

The Atlas Square Aluminium Roof Lantern is a striking architectural rooflight designed to maximise natural light while maintaining a perfectly balanced, symmetrical appearance. With its clean geometric design and slim aluminium structure, it creates a bold centrepiece for modern extensions and flat roof spaces.

Precision engineered from thermally broken aluminium, the Atlas Square lantern allows large areas of glass while maintaining exceptional structural strength and long-term durability. Its symmetrical four-sided design draws light evenly into the room below, creating a bright, open atmosphere that enhances both modern and contemporary interiors.

Designed with the same attention to detail found across the Atlas range, the Square Roof Lantern features slim sightlines, high-performance glazing options and a premium powder-coated aluminium finish. The result is a sleek and elegant roof feature that blends architectural design with outstanding performance.

Manufactured in the UK and made to bespoke sizes, the Atlas Square Roof Lantern is ideal for flat roof extensions, kitchen islands, dining spaces, garden rooms and architectural new builds, creating a dramatic focal point that floods interiors with natural daylight.
