Maximum permitted wind strength

The sun protection system has been constructed so that the largest size meets the
minimum requirements for wind resistance class 2 in the CE conformity classification
(see table 1.4). Depending on the projection, it may also meet resistance class 3. The
wind resistance class after the system has been installed depends largely on the type and
quantity of fixing materials used and the surface it is installed upon. The sun protection
system may only be used up to the wind resistance class declared by the installer.
