Roller Blinds

Roller blinds: precise solar control for every type of space

What roller blinds are and how they work

Roller blinds are one of the most sought-after solar control systems in both residential properties and professional interior design projects. Their mechanism is simple and effective: the fabric is attached to an upper roller tube that collects and deploys it in a controlled manner, precisely regulating the entry of light and heat in any room. Unlike other systems, professionally manufactured roller blinds allow the use of high-performance technical fabrics that not only control light but also reduce thermal gain and protect against deterioration caused by ultraviolet radiation. At Cortinsa we manufacture every unit to measure, with widths of up to 600 cm and heights of up to 250 cm, guaranteeing a perfect fit for any opening or window, from residential apartments to large commercial façades. The combination of clean design, silent operation and durability makes made-to-measure roller blinds a popular choice in homes, offices, hotels and restaurants seeking a professional and long-lasting result.

Technical fabrics: screen, blackout, Soltis and canvas

The choice of fabric is the most important decision when specifying a roller blind for any project. Screen roller blinds filter up to 95% of solar radiation whilst maintaining outward visibility, making them the preferred option for offices, hotels and spaces where natural brightness is to be preserved without compromising privacy during daylight hours. Blackout roller blind fabrics guarantee complete light blockage, ideal for bedrooms, projection rooms or any space requiring total darkness. Soltis technical fabrics offer superior performance in dimensional stability and durability, particularly suited to hospitality and corporate office projects where specific technical specifications are required. Translucent roller blinds filter light whilst maintaining a bright and warm atmosphere, ideal for living rooms and workspaces where complete darkening is not required. Canvas, on the other hand, provides a more decorative character, suitable for residential settings where aesthetics take precedence. In all cases, Cortinsa works exclusively with premium materials selected for their long-term technical performance.

External roller blinds: guides, cassettes and motorisation

When an external roller blind is installed on façades, large windows or covered terraces, the choice of guide system is decisive for its durability and performance. Cortinsa works with three systems: aluminium channel, Ø3 mm stainless steel cable and guide-free installation for interior applications with no wind exposure. For exterior use, channel guidance offers greater resistance and a more airtight seal against wind, whilst the cable presents a more discreet and linear aesthetic. Concealment of the mechanism is achieved via a protective cassette — available in curved, straight or square versions — which shields the rolled fabric from sun exposure and dirt. Regarding operation, motorised roller blinds allow the system to be integrated into home automation installations with wind, rain and sun sensors that manage opening and closing automatically. The waterproof external roller blind is particularly in demand for hospitality and catering projects where terraces require functional protection throughout the year. Cortinsa’s external roller blinds are manufactured with a powder-coated aluminium structure and stainless steel fixings. For large-format projects, the external screen roller blind with integrated cassette is the most complete technical solution for façades and large glazed enclosures.

Professional roller blind installation in Barcelona and Madrid

Cortinsa has been installing made-to-measure roller blinds in residential, corporate and hospitality projects in Barcelona and Madrid for over twenty years. Our process includes a technical site visit, on-site measurements, personalised advice on fabric, guide system and concealment, made-to-measure manufacturing and installation by specialist fitters. We work on both new-build and refurbishment projects, coordinating with architects, interior designers and contractors to ensure perfect integration of the system into the space design. The technically robust and durable external roller blind is one of the most requested elements in our corporate and hospitality projects, where efficient solar control directly impacts the thermal comfort and energy efficiency of the building. For industry professionals, we make technical data sheets, CAD specifications and BIM files available in our Cortinsa BIM Library.
