Wide-span drama in a format that suits narrower extensions. The Traverse 800 × 2600 stretches horizontal glazing bars along a 2.6-metre length, creating panoramic overhead light that transforms corridor-style spaces. Built on the Infinity S1 system with Thermlock® technology for exceptional thermal performance.

Traverse Wide Span Roof Lantern — 800 × 2600

The SmartaView Traverse 800 × 2600 expands on the narrow-span concept, introducing additional width while maintaining the clean, directional flow that defines the Traverse design. At 2.6 metres in length, the horizontal glazing emphasis creates a continuous strip of overhead light — enhancing both brightness and the perceived scale of the space below.

The increased 800mm width delivers a stronger visual presence without losing the sleek, elongated character that makes this format so effective in narrower extensions. It strikes a balance between subtlety and impact — ideal where a standard lantern would feel too bulky, but more glass presence is desired.

The ultra-low-line external profile keeps the outside appearance clean and refined, while consistent 50mm sightlines maximise the glazed area internally.

Built on the Infinity S1 system, the deep internal bars provide the structural integrity required for this span without the need for tie bars. Thermlock® multi-chamber technology ensures excellent thermal performance, 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.
