MULTIPLE SETTINGS

The UMBRA system allows four different types of roofing installation, with multiple applications, ranging from construction and industrial projects, roof repairs and renovation, shipbuilding to various types of events.

COST EFFECTIVE

The lightweight aluminium roof components and smart joints work in tandem to reduce labor requirements, streamlining setup and enhancing efficiency.

Components pre-assembled on the ground can be swiftly and accurately installed on the desire location using a crane, saving time and resources.

STRONG AND DURABLE

The inherent corrosion resistance of aluminium makes it an excellent choice for outdoor applications, as it does not rust like iron or steel roof systems.

The stiffer joints and lower self-weight significantly enhance the structural performance of Catari UMBRA. This improvement allows for various combinations of spans, wind and snow conditions.

Keder tarpaulin

Tarpaulins used in the UMBRA system are designed with a Keder cord along their edges. This Keder cord is a flexible rope-like insert made of PVC, which allows the tarpaulin to be securely attached by sliding it onto the track present on the Keder beams. These tarpaulins, certified according EN 13782, are not only practical but also fire retardant, ensuring safety on the job site.

Keder beams

The main beams are equipped with a Keder rail on the top, precisely developed to create a gapless and seamless connection between the fabric and the aluminium bearing structure. This smart design ensures a weather-resistant seal, resulting in a waterproof roof covering, providing optimal protection. To connect the Keder beams, spigots are used, fastened by pins. These pins feature a conic head-end, enhancing their fitting into the holes, resulting in a considerable reduction of assembling times.

Granted Mercantile Hotel, Dublin

Catari UMBRA was installed to offer temporary protection during ongoing renovation work. Spanning across 750m2 and standing at 18 meters tall, Catari's technicians devised a solution that seamlessly integrated with the existing on-site scaffolding. As the site resides in the commercial and tourist hub of Dublin, the roof was pre-assembled at the client's facility before being transported and placed in its designated spot. This approach allowed for a swift installation, completed in just two nights.

Chapel of the Mother of God Nova Ves, Zagreb

During the renovation and structural reinforcement works, a temporary roof was vital to protect the elegant baroque chapel's interiors from harsh weather. The challenge was installing Catari UMBRA on a narrow 7.5 m span while ensuring the façade scaffold supported demanding winds without straining the chapel's delicate walls.
