OTIIMA

Larglass

OTIIMA LARGLASS is yet an original system made of fiberglass, offering low thermal conductivity (U= 0.40 W/ m2.K) meeting easily demanding energy efficiency certifications.

Features


Description

Fiberglass is known as the best insulating material and only requires minimal maintenance, making it the best solution for keeping the heat inside and the cold outside the building. OTIIMA has a constant mindset in implementing eco-friendly solutions, and the application of fiberglass positively contributes to reducing electricity bills by up 50% either for heating or cooling purposes.

Performance

In addition, this system eliminates the risk of moisture and condensation on the surface of the glass or on the profiles. Its structural resistance is highly capable, which allows using slim profiles even in large glazed panes. It is highly resistant to corrosion and rotting, even in more aggressive environments.

Series

Available in double or triple glass.

Configurations

Available configurations include fixed windows, multi-panel and sliding windows/doors (including pockets and corner-opening configurations).


Door automation can be integrated with all of our sliding doors.

March 27 marks the anniversary of Ludwig Mies van der Rohe, one of the most influential architects of the 20th century. His philosophy, built on clarity, simplicity, and material honesty, continues to inspire contemporary architecture. His work embodies a timeless vision that remains as relevant as ever. Here are five key lessons architects today can learn from Mies van der Rohe. Less is More Perhaps his most famous principle, “Less is more,” summarizes Mies’ approach to design: stripping away the unnecessary to reveal the essential. His buildings are characterized by clean lines, open floor plans, and an absence of ornamentation. This philosophy encourages architects to prioritize spatial clarity and material integrity, resulting in structures that are modern and enduring.

Scandinavian architecture and design represent a deep connection between nature, functionality, and the human experience. Grounded in a landscape of vast fjords, endless forests, and soft northern light, it reflects a unique philosophy and way of life. The Origins  The origins of Scandinavian architecture date back to the Viking era, when timber structures and intricate carvings reflected a profound connection to materiality and craftsmanship. As centuries unfolded, this reverence for natural materials persisted, evolving with the changing needs of modern society. The early 20th century witnessed the emergence of Nordic Classicism, a restrained yet elegant style that soon gave way to a more functional and human-centric approach: Scandinavian Modernism.

Belgium’s topography is a delicate balance between history and modernity. From Bruges's medieval charm to Antwerp and Brussels's bold contemporary structures, architecture here is a study in balance. Minimalism finds a profound expression where clean lines, raw materials, and seamless transitions define space. At OTIIMA, we are privileged to contribute to this evolving narrative, shaping spaces where glass dissolves into air, thresholds blur, and architecture becomes an experience. In Belgium, three projects reference our philosophy: Villa Izegem, Villa P, and Villa V à Harelbeke. Villa Izegem | Govaert & Vanhoutte Architects Villa Izegem is an ode to minimalism in its purest form. Govaert & Vanhoutte Architects sculpted a space where vast glass expanses erase the boundary between nature and dwelling. The land breathes through the structure, light carving its way across surfaces, shifting with time. OTIIMA’s ultra-slim profiles amplify this sense of weightlessness, ensuring that nothing interrupts the dialogue between inside and out. The villa is not simply inhabited; it’s a quiet retreat where transparency is the ultimate luxury.
