Frequently Asked Questions
CDL or classic slats?
CDL offers the best opacity and wind stability – ideal for street locations and large openings. GL/Z slats are more flexible and more economical.
Front-mounted vs. top-mounted?
Front-mounted is flexible (renovation/new build) and avoids thermal bridges. Top-mounted sits on the window, integrates very discreetly into the facade, and achieves very good insulation values.
Automation & smart home?
Control via switch/radio/app. With sun/wind sensors, the system automatically adjusts based on weather.
