The flagship of the Apex Collection. At 3200 × 4800, the Pavilion delivers over fifteen square metres of overhead glazing — the most dramatic residential roof lantern in the SmartaView range. Subdivided panels, Thermlock® technology, full S1 security, and deep internal bars supporting this exceptional span without tie bars.

Pavilion Grand Roof Lantern — 3200 × 4800

The pinnacle of the Pavilion range. At 3200 × 4800, this is one of the most ambitious residential roof lanterns available — delivering over fifteen square metres of uninterrupted overhead glazing and creating a truly breathtaking architectural centrepiece.

Designed for the most prestigious projects, the SmartaView Pavilion transforms entire rooms into light-filled, design-led spaces. The carefully engineered subdivided glazing layout maintains perfect symmetry and proportion, even at this exceptional scale — ensuring the structure feels refined, not overwhelming.

At this level, every element of the Infinity S1 system is pushed to its full capability. Deep internal structural bars span without the need for tie bars, preserving completely open sightlines. Thermlock® thermal technology works to manage heat retention across the expansive glass area, while ultra-slim 50mm sightlines maximise daylight and minimise visible framework.

A full high-security specification is built in as standard — ensuring that this statement feature performs as well as it looks. Triple glazing is strongly recommended, and structural engineer approval is essential prior to installation.

Manufactured using the Infinity S1 aluminium system with Thermlock® multi-chamber thermal technology and high-performance 28mm toughened safety glazing, the Pavilion represents the ultimate expression of modern roof lantern design — suited to high-end residential and architectural applications.
