WINDBREAK NETS

It's well known that frequent and intense winds can cause significant damage to crops or greenhouses. Therefore, windbreaks are essential, especially in particularly windy areas.
Benefits of windbreak nets:

  • Mitigation of the mechanical effects of wind.
  • Reduction of evaporation and transpiration of water from the soil.
  • Reduction of frost and frost caused by cold air inflows and consequent savings in greenhouse heating.
  • Retention of fumes, harmful fumes, salt and sand carried by the winds.

The optimal windbreak net is a 50% net. This type of net can protect a distance of up to 8-10 times its height without creating turbulence or vortices (e.g., a 2-meter high net would protect 16 meters). If the nets are also required to eliminate salt or other dust, denser nets such as 60 or 70% are needed.
Using nets that are too dense (e.g., 90%) is not recommended because they can create vortices upwind or downwind that can cause greater damage than the original wind would have caused.

Sewing on the edge of the nets a HDPE polyethylene cord (ø 4 mm) useful for a secure fixing and to significantly extend the resistance and durability of the windbreak nets

Assembly tips and accessories

Arrange a series of iron, concrete, or wooden posts at a distance that must take into account the height of the barrier and the diameter of the posts.

Space between posts diam. 8/10 cm
– Distance for posts 2 to 2.5 metres high: approximately 3 metres
– Distance for posts higher than 3 metres: approximately 2 metres

 

Fixing the net
Fix the net to the head posts using wooden slats or rubber profiles.

ZINC-ALUMINUM STEEL WIRE
art. FI4
Zinc-aluminium coated steel wire ø 4 mm – for ridge wire
1 Kg = 10 m
Resistance: 980 N./ mm²
Average elongation 4 – 5 %
Packaging: 50 -100 kg

Support cables:
Place the wires or ropes on the side of the posts facing the prevailing wind, at a vertical distance of 40/50 cm. Anchor the end posts with another inclined support.

Attaching the mesh:
Use a pair of ring-type netting pliers to secure the mesh to the cables, spacing the rings approximately 50 cm apart.
This system is quick to install and guarantees excellent, long-lasting hold, even over the years.
