The advantages of ROMA CDL at a glance

The ROMA CDL slat sets new standards in external solar shading. It combines state-of-the-art design with innovative technology and thus offers exceptional added value for living comfort and architecture. Whether precise light control, reliable privacy and glare protection or increased wind stability - the CDL stands for an intelligent solution that harmoniously combines protection, function and aesthetics. Developed and produced in Germany, it meets the highest standards of quality and durability.

Directing or dimming daylight

The ROMA CDL slat ensures maximum daylight comfort - whether you are working, relaxing or watching TV. It prevents annoying direct light on screens and reliably provides thermal insulation in summer. Thanks to the intelligent technology, the daylight can be flexibly directed or dimmed - for a pleasant room climate at any position of the sun.

The opaque eye-catcher

The elegant design of the ROMA CDL External Venetian Blinds fits perfectly into modern façades with clean lines. When closed, the slats become a stylish eye-catcher that also offers maximum privacy. The overlapping construction and the specially developed ROMA CDL guide rail make the system opaque - even in illuminated interiors in the evening or when viewed from the side.

More than just looks - comfort meets design

The ROMA CDL is not only visually impressive, but also offers completely new functions thanks to its innovative design. The newly developed slat design creates a perfect balance between architecture and comfort. With the ROMA CDL slat, building owners, architects and planners have a solution that combines modern design and technical progress - a new level of External Venetian Blinds.

ROMA CDL slat defies high winds: stability in all weathers

The ROMA CDL slat impresses with greater wind stability thanks to its particularly robust design: special slat bolts, an innovative roller carriage and the optimized ROMA CDL guide rail ensure that your sun shading remains reliable in use even in strong winds.

Push-up protection against break-in attempts

The ROMA CDL slats not only offer convenience, but also safety. The roller carriage has an integrated anti-lift device that effectively blocks even the slightest attempt to force it upwards. This makes attempted break-ins much more difficult and gives you added security - for a good feeling at home.

Opaque even from the side

The high slat overlap and the special side guide make the ROMA CDL External Venetian Blinds particularly efficient against side views and unwanted light incidence. Compared to classic External Venetian Blinds, it therefore offers significantly more privacy and improved darkening. Ideal for living spaces where privacy and daylight control are equally important.
