Four square metres of overhead sky. The Zenith 2000 × 2000 delivers the kind of natural light that changes how a room feels entirely — making large extensions, orangeries, and open-plan living spaces feel bright, connected, and alive. Thermlock® technology ensures the thermal performance matches the ambition.

Zenith Square Roof Lantern — 2000 × 2000

Four square metres of overhead sky — the SmartaView Zenith 2000 × 2000 delivers the kind of natural light that completely transforms how a space feels. Large extensions, statement living areas, and orangeries gain a dramatic centrepiece that visually connects the interior to the sky above.

At this scale, Thermlock® multi-chamber thermal technology plays a critical role, delivering a centre pane U-value of 1.0 W/(m²K) to effectively manage heat loss across a large glazed area. Triple glazing is recommended for optimal year-round comfort and performance.

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.
