Key Facts

  • Fleece is mainly used to control temperatures in early crop production.
  • There is a substantial difference in the micro climate created between a cheap fleece and a quality fleece. Covertan® has much higher values for air and water permeability and has improved light transmission.
  • Covertan® should last 1-2 seasons and it has the strongest and most reliable joins currently on the market.
  • It must be laid tight like a bed sheet as it is designed to stretch as the crop grows. It has over 30% stretch.
  • If laid loose it can flap and may damage the emerging crop.
  • Fleece is best secured by using soil or sandbags.
  • It is normal practice for growers to spray both herbicides and fungicides through Covertan® but the fleece must be completely dry for it to work effectively.


  • Covertan® & Novagryl® over 10.5m wide have reinforced edges as standard.
  • Available in 17, 19, 22, 30, 40 and 50 gram weights.

Fleece was first developed by Fiberweb France in the early ‘80’s to protect fruit & vegetable crops from frost and promote earlier harvest dates.


30 years later Fiberweb are the worldwide market leader in agricultural nonwovens and they still produce their original fleece, Covertan®.
