Cosabella SD-36

From private villas and penthouses to luxury hotel suites and monumental architecture, it minimizes visible profiles in ambitious openings designed to evoke a sense of infinity. With a visible central interlock of just 20.6 mm, it brings the view directly into the heart of everyday life. Supporting high-performance glazing combinations up to 34 mm, SD36 gives architects unlimited design flexibility with three installation options: above the floor, recessed into the floor or fully concealed beneath the floor finish. Certified Class 7A watertightness, Class 4 air permeability and C5 wind load resistance create an architectural signature meeting global standards.

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.
