HORTICULTURAL TEXTILES
Protective Cloth Reducing the impact of wind damage Even moderate wind causes loss in productivity and quality through:
• Artificial windbreak/shelter cloth is instant.
1. High evapotranspiration rates (plant stress). 2. Physical damage to plants.
• Windbreak shelter cloth can be designed to give predictable performance.
3. Disruption of sprinkler distribution patterns.
• They don’t harbour pests and diseases.
4. Time and cost to replace damaged plants.
• Minimal maintenance with a minimum 10 year pro rata UV life.
5. Reduced yield.
• Minimal shading of the productive area.
The ideal windbreak should filter the wind, reducing the velocity in the protected area by pushing the bulk of fast moving air above that zone. In intensive horticulture situations, artificial windbreaks have distinct advantages over natural trees. The speed of the wind is reduced as it filters through a windbreak, giving numerous beneficial effects. Although plant species react differently to wind protection because of their different forms, windbreaks generally give increased and earlier crop yields. Without a windbreak, leaf surface can be damaged sufficiently to reduce yields.
The bottom line: Windbreaks reduce wind speed and modify the microclimate of sheltered areas. Overall, these changes improve plant quality and growth. Empak stock a comprehensive range of knitted artificial shelter cloths in white, black or green colours, from 0.91 metre widths right through to 5 metre, in three porosity (percentage of wind block) options depending on load requirements. Typically white shelter cloth is the preferred option for use in kiwifruit blocks, as the colour enhances light reflectivity reducing the effects of shading.

Specifically designed to assist in protecting crops from hail damage. With the small triangular knitted hole shape and robust construction of 75g/m2 in weight, the standard roll configuration is 6.5m wide x 200 metres in length. A unique feature is five sets of reinforced eyelets spread across the width of the roll, which effectively allows the roll width to be cut down to multiple widths to suit the end use application without fraying.
