Required ballast | Germany
General
The ValkTriple® mounting system must be reinforced by means of tiles, which must be placed on the
indicated ballast foundations. In three steps you can easily calculate the required ballast;
• determine the wind area on the windmap
• choose the wind area and building height in the table
• you can now read the number of tiles / kg
Note 1: The extra ballast must be equally divided over the ballast foundations.
Note 2: The max. of 32 tiles can be placed for extra ballast (288 kg).
