Duisburg lives with water, harbor areas, and open corridors. This does not automatically make a summer spot stormy, but for a shade sail, it serves as a reminder of an important truth: wind load belongs in the planning phase, not in the fine print. At the same time, there are many sheltered courtyards and gardens where custom shading noticeably enhances the outdoor area.
UNICOVR shade sails are made to your dimensions – for private terraces, catering businesses, company premises, or social facilities.
Protected in the courtyard, exposed in open locations
A sail between buildings experiences different currents than one on an open plot. That is why we consider not only the square footage but also the height, environment, and ease of removal. In gusts of wind, any additional surface area acts as a lever on the wall anchor, mast, and foundation.
Our guide on wind and storms explains when it is better to take a sail down.

Shade for commercial and break areas
Robust processes count on business premises: Who checks the tension? Where is the removed sail stored? Do rescue and transport routes remain clear? Such questions sound less appealing than "summer lounge," but in everyday life, they determine whether the solution works. Further information can be found on our page for companies and commercial clients.
Keeping out rain or letting air through
Waterproof polyester can protect a seating area from rain. It must be installed with a slope so that water drains in a controlled manner. HDPE allows precipitation to pass through, ensuring an airy shaded spot. The material decision should be made before determining mounting heights, as both variants are planned differently.
Those primarily looking for shade and air circulation are usually well served with HDPE; rain can drain through the fabric. If a dining or guest area needs to remain usable during a shower, waterproof polyester is an option. In that case, the slope and water drainage must be determined from the start.
