Pavilion Grand Roof Lantern — 2000 × 3800

The entry point to the Pavilion range — and already a commanding architectural presence. The SmartaView Pavilion 2000 × 3800 is designed for larger extensions where scale must be carefully controlled, using subdivided glazing panels to bring structure, balance, and proportion to over 7.5 square metres of overhead glass.

At this size, the Pavilion design comes into its own. Rather than relying on long uninterrupted spans, the panelled configuration introduces rhythm and visual order — creating a ceiling feature that feels refined, intentional, and architecturally composed.

Ideal for orangeries and prestige extensions, this format delivers expansive natural light while maintaining a sense of structure that complements larger rooms.

Built on the Infinity S1 system, the Pavilion combines deep internal bars for structural integrity with clean, consistent 50mm sightlines. Thermlock® multi-chamber thermal technology is essential at this scale, ensuring strong thermal performance across the entire glazed area, delivering a 1.0 W/(m²K) centre pane U-value as standard.

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.
