At OTIIMA, we believe in the seamless integration of design and functionality, and OTIIMA Fusion exemplifies this philosophy. Designed as an extraordinary-slim system, it combines the versatility and flexibility of our Classic series with a hidden sill design that is as ingenious as it is practical.
Innovative Hidden Sill Design
Central to the OTIIMA Fusion system is its hidden sill design, which ingeniously utilizes a single slot for each track. This unique feature not only enhances the system’s aesthetic appeal but also ensures effortless integration with the finished materials. The result? An ideal floor frameless glazing solution for contemporary villas and cutting-edge architectural high-rise buildings.
