PATURA Wind Protection Systems

Fresh air for healthy animals

Well-ventilated buildings greatly increase animal health and hygiene. PATURA wind protection systems ensure natural ventilation conditions. The mesh material is suitable for all weather conditions. It reduces the wind speed by up to 82 % (wind reduction factor) and offers gentle ventilation of the building without draughts.

Heat build-up = Stress

A cow gives off up to 10 litres of water vapour into the buildings air per day. This, together with the other condensing water, leads to stress in the animals if the ventilation is inadequate. Heat and damp lead to problems in fertility and feed consumption in high-performance animals.

PATURA wind protection systems offer 3 important advantages for stress-free and healthy animals

Fresh air without draughts
Dry conditions
Natural light

Even in buildings PATURA wind-protection systems offer the animals many of the advantages of life in the open air.

Assessment of wind protection netting

Various technical properties are important for assessing the effectiveness of wind protection and ventilation systems. The number, the size and the type of opening, as well as the choice of the basic material, have a decisive influence on windprotection and air transmission.

The correct building ventilation system to meet your demands

Permeability

Permeability "P" shows the ratio of opening in the mesh in relation to the overall mesh surface.

Wind reduction factor

The wind reduction factor "E" is calculated as:

Wind speed of 100 km/h in front of the special mesh = 40 km/h behind it

Air transit factor

The air transit factor "CM" gives the relationship between a net-covered surface and a surface with free air entry, for the same air transit.

For the same air transit:
Free surface x CM = Net surface

Opening of 1.00 m² => with special mesh 1.80 m² => with high-performance mesh 6.00 m²

Wind Protection Systems

PATURA wind protection netting consists of PVC coated polyester of flat woven thread in cross weave. All cross-over points are firmly bonded together. The material is UV stabilised, antistatic, rot-resistant, tear-resistant, non-toxic and fire retardant as per National Fire Protection Association Hazard Rating B1.
The PATURA warranty comprises a 24-months full warranty for all wind protection netting systems, an extended 3-year warranty for motors and control systems, as well as a graduated 10-year warranty for UV-stabilisation.
