OR Curtains: the large-format solution that few manufacturers can guarantee

What large-format curtains are and when they are needed

Large-format curtains are a type of roller solar-control system designed to cover surfaces that far exceed the capabilities of a conventional curtain. When a corporate building, a car dealership or a shopping centre needs to cover a glazed façade spanning tens of metres in width, standard systems cannot deliver the result without resorting to multiple panels joined by overlaps that compromise the visual outcome and the uniformity of the installation. The Cortinsa OR Curtain solves this problem at source: a single continuous piece of screen fabric up to 40 metres wide and 6 metres high, with no joins, no overlaps and perfectly uniform tension across the entire surface. The circular lower rail acts as a counterweight and controls the rolling and unrolling of the fabric in a precise manner, with integrated motorisation that manages movement accurately regardless of the weight of the installation. You can view the rest of our made-to-measure curtain solutions to find the system best suited to each type of space.

Technology and technical complexity: why few manufacturers can offer a guarantee

A large-format roller curtain is not simply an enlarged conventional curtain. The behaviour of the fabric at large scale, the management of tension across the full width, the overall weight and the precision of the rolling system are factors that require specific engineering and installation expertise that very few professionals possess. The screen curtain for large surfaces must maintain the flatness of the fabric without deformation or undulation along the entire panel, even with the changes in temperature and humidity that affect exterior technical fabrics. The lateral guide system — mandatory in the OR Curtain — is the element that guarantees the alignment of the panel during movement and prevents deviations that, in large formats, would be impossible to correct on site. Cortinsa has developed and refined this system over many years, carrying out installations in corporate buildings, dealerships and large-format spaces where technical and aesthetic demands are at their highest.

Applications: corporate buildings, dealerships and shopping centres

The dealership curtain is one of the most common use cases for the OR Curtain. Automotive showrooms need to cover large-format glazed façades that in many cases exceed 20 or 30 metres in width, with the additional requirement of maintaining visibility of the vehicles on display from outside. The screen fabric of the OR Curtain filters direct solar radiation — which deteriorates interiors and causes overheating — without blocking the view, making it the ideal technical solution for this type of installation. In corporate buildings with glazed façades, the OR Curtain manages glare in open-plan office floors where the surface to be covered on each floor can easily exceed 15 or 20 metres. The motorised curtain for large surfaces allows opening and closing to be programmed according to solar orientation and time of day, integrating with building management systems (BMS) for fully automatic regulation. In shopping centres and high-footfall spaces, the shopping centre curtain with screen fabric reduces the greenhouse effect in areas with glazed roofing or glazed façades, improving thermal comfort for visitors and reducing the load on the building’s air-conditioning system.

Professional installation of OR curtains in Barcelona and Madrid

Cortinsa carries out the installation of large-format curtains in corporate, commercial and industrial projects in Barcelona and Madrid. The process begins with a technical site visit to assess the actual dimensions, the type of support structure available, the solar orientation of the façade and the motorisation requirements of the project. Following that visit, the Cortinsa technical team sizes the installation, selects the most appropriate screen fabric according to the required solar factor and produces a detailed quote with manufacturing and installation lead times. The seamless roller curtain is manufactured entirely to measure in a single piece, which requires precise technical coordination between the factory and the installation team.
