Coverings are a very important choice because they represent the location where maintenance costs are concentrated.
For these reasons they must be:
- long life
AGRIMEC installs several types of materials:
European norm: EN 13206:2001
Film duration: it’s determined following the procedure described in the European norm EN13206, exposing plastic film in suitable machines equipped with specific lamps (those lamps irradiate a radiation similar to solar type).
To determine film duration, the adopted criterion only considers material degradation obtained in laboratory through the quick artificial ageing (Weather-o-meter or Wom).
The duration of a covering material is proportional to the period of exposure to the artificial ageing after which mechanical properties are not considered as more sufficient.
