Covertan is made from a single polymer - polypropylene, which is recyclable. This even includes the bonding used in wide width products.
Covertan 17 is our benchmark product. With 17g per square meter, it is the lightest of our range. Thick filaments and isotropic distribution give it a good air and water permeablity and a very good mechanical strength. This permeability effect combined with windbreaks creates a micro-climate that enhances crop growth. Covertan 17 is available in various standard and customised widths to suit all fields.
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 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 30 has been specially designed for winter protection of crops. With its heavy weight, 30 Covertan protects damage from frost and snow. Selected permeabilty manages airflow and can reduce the impact of sudden changes in temperature. This helps avoid excessive dehydration in plants during overwintering.
Designed to protect plants in containers or saplings Covertan 60 is the thickest and strongest fleece in our range. Its heavy weight (60 g / m²) makes it a very effective windbreak that protects plants exposed and maintains good thermicity. It can be used in extreme climatic conditions.
Covertan is manufactured by Fiberweb from polypropylene pellets. This polymer is extruded into filaments that form a basic web. The filaments are then bonded together by a process called hot calendering: there is no chemical binder. Individual fleece layers are then joined together with molten polypropylene to create wide and ultra-wide roll widths. The fleece is made from polypropylene which facilitates recycling.
