Installation Effect
  • Duck feather thermal cover does not absorb moisture easily, so it keeps the inside of the house comfortable and reduces the occurrence of harmful insects.
  • Increasing corp yields by reducing damage caused by cold damage and accelerating crop growth with excellent thermal.
  • Growing evenly by reducing edge and temperature deviation covering the crop with an insulating tunnel rather than heating the entire film-house to reduce heating.
