Cosabella SD-35

From high-ceilinged spaces and coastal buildings to hotel lobby transitions and spacious villa verandas, it delivers unwavering performance in enormous openings exposed to extreme wind loads and severe weather. Its 94 mm sash profile and an interlock reduced to 40 mm with 90° assembly provide uninterrupted panoramic views. Supporting acoustic and triple-glazing combinations up to 40 mm, SD35 gently lifts and smoothly slides large sashes weighing between 200 kg and 400 kg. Independently tested Class 9A watertightness, top-level Class 4 air permeability, a 16/28 mm thermal break and C4/B4 wind load resistance completely isolate interiors from external conditions, even in the strongest storms.

Cosabella Integrated Manufacturing Assurance: From design and extrusion to surface finishing and complementary accessories, all components are manufactured in Cosabella’s own integrated facilities in accordance with international Qualicoat and ISO quality standards. This integrated infrastructure ensures maximum system compatibility, long-lasting mechanical performance and consistent, measurable quality across all our products.
