Pavilion Grand Roof Lantern — 2800 × 4200

A statement in scale and light. The SmartaView Pavilion 2800 × 4200 delivers nearly twelve square metres of overhead glazing — designed for spaces where the roof lantern becomes the defining architectural feature.

At this size, precision is critical. The Pavilion’s subdivided glazing layout controls the span with clean, symmetrical sightlines, while the Infinity S1 system’s deep structural bars provide the strength required without compromising the open, refined aesthetic. The result is a lantern that feels expansive yet perfectly composed.

Thermlock® thermal technology works alongside high-performance 28mm glazing to achieve a 1.0 W/(m²K) centre pane U-value — essential for maintaining comfort across such a large glazed area. A full Infinity S1 security specification is included as standard, ensuring performance and protection are built in.

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