Covering and technical materials

Coverings are a very important choice because they represent the location where maintenance costs are concentrated.
For these reasons they must be:

  1. long life
  2. efficient
  3. resistant

Polyethylene film

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.


Film classification on the base of artificial accelerated ageing

Film class Duration (hours)

≥ 400
≥ 1700
B ≥ 3200
C ≥ 4600
D ≥ 6000
≥ 7300
