Otiima
Otiima is a Portuguese manufacturer of high-performance minimalist glazing systems, built around a single design principle: eliminating the frame from view while maximizing what matters. Ultra-slim aluminum profiles, flush sill-to-ceiling glass, and a complete lineup of opening typologies give architects and designers a genuine blank canvas for projects where glass and light define the architecture.
​
Available through Ultimate Windows, Doors & More across Eastern Canada, Otiima brings a level of minimalist precision to the Canadian market that few glazing systems can match.
Otiima Plus
The Plus series is Otiima's most recognized system, a multiple design-award winner for its flush head and sill track construction and its homogeneous aesthetic from frame to glass. Unlike recessed-track systems, Plus delivers a true flush floor-to-ceiling plane in 26mm, 38mm, and 54mm glass configurations. The 54mm triple-pane option is specifically engineered for colder climates, noise reduction, and impact performance, making it the most relevant series for the Canadian climate.

The Otiima Product Lineup
Otiima's four product series cover the full range of minimalist glazing applications, from entry-level flush-frame systems to the most thermally demanding cold-climate installations. All four series share the same design language and opening typology program, and all are available in horizontal sliding, vertical sliding, pivot, curved, and skylight configurations.
Otiima Vision
The Vision series pushes thermal performance further, with a 62mm glass option that achieves thermal transmittance values of Uw 0.47 W/m²K and sound insulation up to Rw 44 dB. Designed for the most demanding cold-climate and acoustic applications, Vision maintains the same flush minimalist aesthetic as the Plus series while offering the deepest performance specifications in the Otiima lineup.
