Fiberweb crop textile | Covertan 22 | climate protection | floating row cover

Covertan 22 (22gsm)

Covertan 22 is a heavy weight general purpose crop cover. Additional material improves the physical strength and robustness during installation and use. Both the thermal insulation and abrasion resistance also improve, resulting in a higher level of protection for demanding crops in demanding environments.

Covertan 22 (22gsm)

Covertan 22 is a mid to heavy weight floating row crop covers when the combined demands of a challenging crop and exposed installations need to be satisfied.

As a further increase to the performance over light and mid weight products, Covertan 22 has a mechanical strength of 147% of the base Covertan 17. Matched with an increase in toughness of 147% Covertan 22 is harder to penetrate and stronger once installed than products for less demanding applications.

Increased mechanical strength is also beneficial where protected crops are abrasive such as strawberries and cucumbers. Lower strength fleece products exposed to continuous contact with abrasive crops can experience holes and loss of integrity.

Covertan creates a growth enhancing micro climate due to carefully selected materials and open structure which giving a low thermicity value, with high air flow. This result in a more uniform temperature (across the field), less variations due to day/night and retaining the radiant heat stored by soil during the day. 

Farmers have the scope to water & fertilize crops to further optimise the yield without removing the crop cover due to the porous structure of the fleece. Covertan's exceptionally highly porous structure and exceptionally low hydrostatic head  allows rapid water pass thorugh, combined with low absorbency enables the product to remain light weight for longer - resulting in less risk of wind damage.

To optimise the use of crop cover, Covertan is available in a wide range of custom and standard sized rolls up to 28m wide. This reduces installation time through minimum roll changes, fewer traverses of the field and less product waste.  All our fleece are Z folded, which makes the installation quick and easy.

Thermal Effect

Thermal Effect ►

Temperature management is critical in controling plant growth. Covertan fleece forms part of a temperature management strategy.

Earliness, Yield & Uniformity

Earliness, Yield & Uniformity ►

Selecting the correct crop cover and using it effectively can significantly improve the economics of a harvest. Covertan has been proven to do this for over 20 years. 

Climatic Protection

Climatic Protection ►

Plants can be damaged by elements such as heavy rain and wind  drying. Crop cover forms a protective layer that can reduce this.

Pest Protection

Pest Protection ►

Preventing the pest reaching the crop is an effective method of reducing crop loss and damage. Covertans breathable structure creates a permeable barrier.

Robustness and Strength

Robustness and Strength ►

Once covered by fleece, the durability of the materials help ensure the longer term protection. Formulated for exposed applications, Covertan is extremely robust.

Light Transmission

Light Transmission ►

Light drives plant growth. Covertan crop cover has a structure that balences openness with the protection required for crops.

Permeability to Air and Water

Permeability to Air and Water ►

Moisture and air balance are major factors in robust plant growth. Covertan crop cover has a structure that balances openness with the protection required for crops.

Durability / UV stabilisation

Durability / UV stabilisation ►

Sunlight is an aggressive degrador of most materials. To overcome this, Covertan is specially formulated with stabilizers that reduce this impact and give targeted exposure life.


Recyclability ►

Covertan is made from a single polymer - polypropylene, which is recyclable. This even includes the bonding used in wide width products. 

Transport Optimisation

Transport Optimisation ►

Transport optimisation, multiple roll widths.

There is no standard field and to create optimal covering Covertan is available in both standard sizes for the most common widths, and  "tailor-made"sizes from 1 to 28 m wide. Rolls are produced with a Z fold for ease of opening and the standard  2.40 m width, fitting within a  truck for easy handling and transport.
