Covertan 17

High moisture transmission to support growth

Covertan 17 helps ensure high moisture transmission, air permeability for temperature stability, and heat retention to drive the early maturation of crops. Covertan 17 allows the creation of a microclimate favorable to crop growth and can therefore help create more consistent and earlier yields. This helps reduce the crop cycle, favoring faster crop rotation.

Covertan 17


  • Thicker fibers make the product robust to protect from occasional extreme weather
  • High resistance to UV radiation helps ensures durability over time
  • High mechanical strength, relevant during installation, protection, and removal which help reduce tearing and save time and labor.
  • Good water permeability for uniform distribution of rainwater and irrigation
  • Good light transmission for effective photosynthesis
