Fiberweb crop fleece | Covertan 19 floating row cover

Covertan 19 (19gsm)

Covertan 19 has increased mechanical resistance and more durability compared to Covertan 17. It is recommended for more sensitive crops or difficult climatic conditions needing more thermal protection.

Covertan 19 (19gsm)

Covertan19 is a mid-weight  floating row crop covers used in more demanding crop / location installations to improve crop yields and shorten harvest times

It creates similar microclimate benefits to 17gsm material . The increased mechanical strength of 125% benefits the integrity of the cover in longer harvest crops such as potatoes, which remain covered for several months.

These increased levels of strength are also beneficial in areas of high elemental exposure such as larger field sizes with high levels of prevailing wind. 

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.

Crops such as Strawberries, Zucchini and Cucumber benefit from the thermal effect of crop cover, however these plants are abrasive and can wear holes in light weight covers. Covertan offers an economic solution to maintain the integrity of the cover, reducing the impact of abrasion through increased mechanical strength. 

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. Covertans 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 19 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.  Installation is also simplified with the option of reinforced edges that reduce the risks during roll-out and staking to ensure the integrity of the fleece is maintained. 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.
