When the brief is maximum visual impact, the Traverse 1400 × 3600 delivers. At 3.6 metres long, the horizontal glazing bar emphasis creates a genuine sense of panoramic openness overhead — transforming large extensions into light-filled, dramatic living spaces. Full Infinity S1 security and thermal specification.

Traverse Wide Span Roof Lantern — 1400 × 3600

When the brief calls for maximum scale and visual impact, the SmartaView Traverse 1400 × 3600 delivers without compromise. Spanning an impressive 3.6 metres, this is a roof lantern designed to define the space beneath it — creating a continuous expanse of overhead glazing that brings light, openness, and architectural presence into large extensions.

At this size, the Traverse becomes more than a feature — it becomes the focal point. The horizontal glazing bars emphasise the full length of the lantern, guiding the eye across the ceiling and reinforcing a strong sense of flow, proportion, and direction within the room.

The generous 1400mm width enhances the feeling of scale, allowing natural light to flood deep into open-plan layouts while maintaining the sleek, linear aesthetic that defines the Traverse design.

Built on the Infinity S1 system, the deep internal bars provide the structural integrity required for this span without the need for intrusive tie bars — preserving the clean, uninterrupted lines. Thermlock® multi-chamber thermal technology ensures that even at this scale, performance remains exceptional, 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 Traverse is a premium choice for extensions, kitchen builds, orangeries, and contemporary architectural projects.
