About Us

Cosabella was born from Alkor Aluminium’s decades-long industry experience and technical expertise. Entirely designed by Turkish architects and engineers, Cosabella offers high-end aluminium window, door, and façade systems developed to meet the aesthetic, performance, and safety requirements of modern architecture.

The name Cosabella—meaning “beautiful thing” in Latin—was carefully chosen for its universal appeal, simplicity, and positive resonance. With its graceful tone in every language, the brand name reflects our deep commitment to elegance and architectural value. It also represents the first strategic step in Cosabella’s ambition to become a globally recognized, contemporary, and visionary building systems brand.

Supported by Alkor Aluminium’s strong R&D team and extensive production know-how, Cosabella merges engineering excellence with refined aesthetics—ranging from sliding systems and curtain wall solutions to high-performance window and door systems. Guided by a customer-centric service philosophy, Cosabella develops premium solutions for sophisticated building projects.

Cosabella is more than a product brand; it represents a holistic systems approach, born at the intersection of architectural creativity and engineering intelligence. With both ready-to-use systems and tailored solutions for unique projects, Cosabella is equipped to meet the diverse needs of the construction industry.

By adhering to principles of ecological design and prioritizing environmental and human health, Cosabella contributes not only to the architecture of today but also adds value to the sustainable future of our built environment.
