We at the renowned company rotec GmbH Berlin are proud to present our project: an innovative, opaque and poke-proof lamella wall, specially developed as a façade element for a gas storage facility in Freiberg (Saxony). When selecting the components, we decided to use the proven Renson L.033V lamella.

We prefer to use these V-shaped louvers from Renson when limited access is required, such as at transformer stations. Not only are they excellent for privacy protection, but they also impress with their exceptional water resistance - a crucial factor for use in demanding environments such as gas storage facilities.

The technical data of our louvre façade speaks for itself: Manufactured from extruded aluminum profile of the alloy EN AW-6063 T66 and arranged at a distance of 33.3 mm, they offer a K-factor (feed) of 61.04 and an optical free cross-section of 60%. Complemented by a physical free cross-section of 43% and Class A water tightness, they stand for maximum performance and efficiency.

At rotec we also manufacture custom single and double leaf doors and gates in our Berlin factory. Our slats can be supplied in anodized EV-1 or powder coated in the desired RAL colors.

As specialists in the construction of industrial ventilation grilles, weather grilles and louvre facades, we always strive to set the highest standards in our industry.

Our delivery service is there for you from Monday to Friday and supplies the greater Frankfurt, Munich, Hamburg, Stuttgart, Cologne and Düsseldorf areas with ventilation grilles, weather protection grilles, smoke extraction hoods, roof enclosures and machine enclosures. Not forgetting our extensive range of soundproofing louvers, which are ideal for parking garage facades.
