Windmap Belgium
Required ballast | Belgium
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).

= the required ballast is higher than will fit under the system. The system must be mechanically attached to the roof. Please contact Van der Valk Solar Systems.
* If you use tiles of different sizes and thus another weight, you need to adjust the number of tiles to get the right weight.
