Hollow elements have been occupying an increasingly larger space in contemporary architecture because they allow integration between projects without completely eliminating visual boundaries. Among the most used solutions, the choice between muxarabi or cobogó appears in projects that seek balance between ventilation, natural lighting and sense of privacy.

Although both resources share the proposal of creating permeability in spaces, each one produces quite different effects in architecture and in decoration. By understanding the characteristics of muxarabi or cobogó, it becomes easier to identify which solution best responds to the needs of the project and the desired atmosphere.
The muxarabi originates from Arab architecture and is traditionally formed by hollow wooden structures with detailed geometric designs. Its main purpose is to allow air circulation and entry of light without completely exposing the projects, creating a more filtered relationship between interior and exterior.

In contemporary projects, muxarabi appears in fixed panels, sliding doors, partitions and light enclosures. The delicacy of the designs and the presence of wood help create more welcoming and sophisticated projects, especially in interiors that value natural materials and a visually quieter atmosphere.
The cobogó emerged in Brazil and quickly became one of the most striking elements of national modernist architecture. Produced in concrete, ceramic or cement, it is composed of hollow blocks that create geometric patterns and allow constant ventilation between spaces.

Different from the visual lightness of muxarabi, cobogó has a more structural and sculptural presence. Besides functioning as a partition, it also creates very striking plays of light and shadow throughout the day. In interiors, it usually appears in facades, hallways, kitchens and transition areas between indoor and outdoor projects.
The choice between the two elements depends on the desired function in the project, the aesthetics of the project and the way light and ventilation will be worked with.
Between muxarabi or cobogó, muxarabi is usually more recommended when the priority is to preserve privacy without visually weighing down the project. The hollow weaves filter the view in a more delicate way, working well in bedrooms, balconies and internal divisions.

The cobogó tends to take on greater visual prominence within the projects. Its modules create texture, depth, and rhythm on surfaces, making it an interesting choice for accent walls, facades, and outdoor areas.

Projects with a more natural and intimate aesthetic tend to work better with muxarabi. The presence of wood helps soften the spaces and reinforces a sense of coziness without compromising ventilation.

The cobogó favors constant ventilation due to its wider openings. In hot regions or areas that need greater air exchange, such as laundry rooms and kitchens, it works as an efficient solution integrated with the architecture.

Muxarabi often appears in movable panels and sliding partitions, allowing the projects to be reorganized as needed. This feature makes a difference in integrated apartments or compact spaces.

Despite the comparison between muxarabi or cobogó, the two resources can coexist within the same project when used in a balanced way. The secret lies in understanding the function of each element and distributing their applications coherently throughout the projects.

While the mashrabiya tends to work better in lighter and cozier internal divisions, the cobogó can take on areas of greater architectural prominence or transition between interior and exterior. When combined with attention to proportion and materiality, both elements help create more ventilated, illuminated, and visually dynamic spaces.
