Lamaxa slat roofs are able to withstand a maximum permissible wind speed of 13.4 m/s according to statistical calculations in accordance with DIN 1991-1-4 'Actions on substructures'. For wind speeds > 13.5 m/s, two adjustment positions can be configured for the slats, depending on the order length: Order length > 5.1 m: Slats opened to at least 90° Order length ≤ 5.1 m: Slats closed Lamaxa fabric roofs achieve wind resistance class 4 in accordance with DIN EN 13561 with a maximum permissible wind speed of 13 m/s.
