Wind Ratings

Models that have been wind tested and wind rated are in conformity with the performance requirements according to UNI EN PR 13561:2004.

The results obtained through experimental and calculation tests, yielded characteristics corresponding to a static nominal wind pressure of  110 N/m2 . The pressure has been applied orthogonal to the fabric surface and operating in a static and continuous way. The Wind Class applies to the specified unit type and dimension, therefore units smaller than the rated size may well yield performances higher than the tested wind class.
