Installation Effect
  • Good thermal effect increases crop yields through even growth of crops!
  • Volume is reduced when rolled up,so it can be installed sufficiently between double and triple vinyl!
  • when installed side, it can be maximized thermal made of duck down and thin cashmilon combined!
Differentiated advantage of duck down thermal curtain
  • Because of hardening, thermal condition of cashmilon begins to fall after 2~3 years but duck down thermal curtain stays strong to maintain thermal and usage gets longer.
  • Professional farm workers recognized it!

What is hardening?

the color is changed and gets hard because of exposing from sun light and moisture.
