Sapphire Windows OTIIMA Plus - Visual of Installation of OTIIMA Plus Structure


OTIIMA PLUS is a technically sophisticated, flushed minimal sliding frame system that guarantees the highest performance with the slimmest aesthetics possible.

Being a Red Dot Design Award winner, extensive research and development were put into this clever sliding system in which the frame profiles are flushed with the construction material finishes of the building.


Redefining Design

The clear lines and innovative method of construction of the OTIIMA 38 Plus window system give it a restrained and refined appearance.

The system is highly watertight, airtight and offers high resistance to wind forces, honouring the best air and water performance in the market.

Along with its sleek aesthetic lines, a patented hidden handle / invisible lock is uniquely integrated to the frame, improving security yet enhancing the clean design of the window system.


Sapphire Windows OTIIMA Fusion - Visual of Installation of OTIIMA Plus Structure


OTIIMA FUSION stands out as a system which is completely built into the finishing materials, as if the window is merged with the building, becoming one.

This system incorporates window frames with reinforced binding polyamides and toughened glass, providing superior thermal and structural performance. It’s an innovative system, completely built-in on all four sides of the frame, providing the perfect fusion and a seamless connection with the interior and exterior spaces.


Absolute minimalism

The FUSION’s exclusive design features a completely redefined, minimalistic frame system by providing the appearance of “floating” glass door panels within the architectural finishes.

Achieve perfect continuity between the interior and exterior with a seamless transition, as the system and drainage are fully embedded into the finishes of the building. An add-on gutter can be incorporated, capable of draining large amount of rainwater even in extreme situations.
