OTIIMA Classic with a twist is the brand’s original take on minimalist window systems, offering a balance between functionality and elegance. Defined by its slim 20mm vertical interlock, the system enables expansive glazed surfaces and maintains a clean, understated aesthetic.
Beyond its visual appeal, the Classic system is engineered for performance. It ensures excellent water tightness, air permeability, wind-load resistance, and thermal insulation. The use of toughened glass enhances durability and allows for large panes, while an exclusive sliding mechanism with stainless-steel bearings offers effortless manual operation.
The Classic system is available in three versions: 16 Classic, ideal for interior use with monolithic glass panels up to 6 m²; 38 Classic, suited for warm to moderately cold climates with 38mm insulated or triple-pane glass; and 54 Classic, optimized for cold climates with 54mm triple-pane glass and enhanced thermal performance.
