The size where a roof lantern starts to genuinely transform a room. The Zenith 1000 × 1000 floods kitchen extensions and dining areas with natural light through its symmetrical glazing bars and ultra-slim 50mm sightlines — creating bright, airy interiors that feel significantly larger than their footprint.

Zenith Square Roof Lantern — 1000 × 1000

One of the most popular square lantern sizes in the UK, the SmartaView Zenith 1000 × 1000 transforms kitchen extensions and dining areas with generous overhead light and a perfectly balanced ceiling feature.

The centred ridge and symmetrical glazing bars create a profile that looks exceptional from every angle — inside and out. Ultra-slim 50mm sightlines ensure the structure never overwhelms the glass, keeping the design light, open, and contemporary.

Manufactured using the Infinity S1 aluminium system with Thermlock® multi-chamber thermal technology and high-performance 28mm toughened safety glazing, the Zenith is a premium choice for extensions, kitchen builds, orangeries, and modern architectural projects.

Thermlock® Thermal Technology
Multi-chamber thermal break with 28mm glazing delivers a centre pane U-value of 1.0 W/(m²K) — far superior to traditional 24mm polyamide systems. Keeps your home warm and energy bills low.

50mm Ultra-Slim Sightlines
Consistent 50mm rafter, hip, and ridge sightlines maximise the glass area, flooding your space with natural light while keeping the frame minimal.

Ultra-Low-Line External Profile
Rafter and hip top caps sit close to the glazing level, and corner end caps run perfectly in line with the perimeter — no unsightly angles, just clean contemporary lines.
