Aluminum external venetian blinds: advantages at a glance

  • Effective heat protection: External blinds block the sun's rays before they reach the window glass. This prevents heat build-up in the building much more efficiently than internal solutions.

  • Optimum light control: The adjustable aluminum slats of the blinds allow flexible regulation of daylight.

  • Energy saving: The reduced heat input reduces the need for energy-intensive air conditioning. This makes aluminum blinds for outdoors an advantageous building block for sustainable living concepts.

  • Design and aesthetics: The visually appealing aluminum slats blend harmoniously into modern façades and offer a wide range of design options.

  • Ease of use: Exterior aluminum Venetian blinds with electric drive enable automatic operation via time programs or the ROMA Smart Home system.

How do aluminum blinds work?

Aluminum Venetian blinds consist of horizontally arranged sun protection slats. These are made of high-quality aluminum, are movably mounted and can be infinitely adjusted. A rail or cable guide for external venetian blinds connects the individual slats together and guides them horizontally in front of the window when the sun shading is closed. When open, the slats are located in the box and are not visible from the outside.

The movable slats allow individual light control. In this way, they effectively protect the occupants from annoying glare without sacrificing natural sunlight. Alternatively, the aluminum slats can also be adjusted so that they effectively darken the interior. This makes them ideal for all rooms - whether in the living room, bedroom, office, study or bathroom.

Areas of application for aluminum exterior blinds

Modern external venetian blinds made of aluminum are suitable for almost any building situation and for a wide range of requirements. They are available in several installation variants and are compatible with various types of external venetian blind slats.

The most common installation variants include

  • Front-mounted blinds: are installed on the façade without interfering with the building envelope. This makes them particularly suitable for retrofitting to existing buildings or in old buildings.

  • Top-mounted blinds: form a single unit with the window and are installed together in the building opening - ideal for new buildings or extensive renovations.

  • Modular blinds: combine modern façade design with effective solar shading and offer maximum design freedom for all buildings.

  • Façade blinds: are ideal for large glass surfaces or office buildings and form a compact system in front of the window.
