Screens as a blanket
To prevent conditioned, both heated or cooled, air from escaping through the greenhouse roof, screen fabrics are used. In this case, the fabric acts like a blanket that keeps the greenhouse warm. The only downside is that screen fabrics reflect the growth light. Therefore, Energy Saving Screens are developed to have insulating properties with the least amount of light loss.
Knitted or Woven
There are several suppliers of high-tech screening fabrics for the greenhouse industry. Energy screens are either woven or knitted. Both production methods use synthetic yarns to create a strong, durable fabric. Beside the production method, there is a difference in quality between energy screen manufacturers because of the use of materials, the quality of plastics and the types of yarns.
