ROMA External Venetian Blind Slats – Conceived for All Weather Conditions

ROMA external venetian blinds are exposed to high loads, the weather and temperature variations. On top of this, they offer a whole host of functional movements to control incoming light. We have specially developed the ROMA aluminium slats to meet all these requirements.

Our external venetian blind slats are made of high-grade aluminium, which is inherently corrosion-resistant and 100% recyclable. High colour and gloss stability as well as exceptional robustness guarantee a safe investment.

ROMA's CDL Comfort & Design Lamella is a world first in this field and has already won the Red Dot Design Award.
