Covertan 19

Increased mechanical resistance for more sensitive crops or difficult climatic conditions needing more thermal protection.

Covertan 19 offers the same high moisture transmission, air permeability for temperature stability, and heat retention properties as Covertan 17, but has increased mechanical strength. Robust and versatile, Covertan 19 is recommended for more sensitive and longer-harvest crops and difficult climates. It is also suitable for areas of prolonged exposure such as larger field sizes with high levels of prevailing wind.
