Much More Than a Window
​OTIIMA windows aren't mere frames; they transcend their function to become integral design elements. They seamlessly complement the architectural vision, dissolving the boundaries between interior and exterior.
Much more than a Window is a trademark property of ECOSTEEL.
Minimalist frames soaring beyond 6 meters create awe-inspiring spaces. Expansive glass panels provide an uninterrupted view, maximizing daylight penetration.
Noise pollution is minimized with innovative soundproofing, creating quieter and more comfortable spaces.
Not limited to glass, it can also accommodate materials such as wood, metal, or tiles as long as they fit within the frame.
Extraordinary Scale
Engineered with Thermal Break technology, argon-filled double glazing ensures year-round comfort; cooler in summer, warmer in the cooler season. All while being cost-efficient.
