125B
Slim sightlines for mild climates.
Demonstration assembly with semantic components — final Orluti extrusion geometry replaces this model via the documented GLB pipeline. Values marked ‡ await test-report confirmation.
Overview
System 125B carries Orluti's fabrication standards into a non-thermally-broken profile for mild climates, interior partitions, and value-driven scopes. The sightlines stay slim, the rollers stay stainless, and the finish options match the rest of the line — at a lighter cost per opening.
Lighter profile, same discipline
Non-thermal-break extrusion machined and glazed to the same tolerances.
Mild climates & interiors
Patios, pool houses, interior partitions, and temperate zones.
Slim sightlines
Keeps the narrow-frame look of the premium systems.
Configurations
O = fixed panel · X = sliding panel, read from exterior. Pocketing versions conceal panels fully within the wall.
