ETFE Glazing

Ethelyne Tetrafluoroethelyne (ETFE) is a translucent polymer glazing material. ETFE has been widely used in Japan for decades, and offers enormous benefits as a greenhouse glazing. Ceres is currently the only North American distributer of this super durable and highly light transmissive glazing material.

We provide ETFE as a glazing option for Ceres HighYield™ kits. We can also sell ETFE for your specific greenhouse needs – whether a retrofit or new build (track distance has to be engineered).

  • High light transmittance, which means higher yields and improved crop quality
  • Fewer greenhouse pests and pathogens, as UV light acts as radiation
  • Strong mechanical strength, capable of resisting high wind and snow loads, and hail
  • Does not degrade or yellow
  • Easily reparable, with ETFE film patches and sheets
  • Recyclable
  • Fire Rated ASTM E84 Class A, ETFE foil shrinks back from plume, which vents fire
  • Stable exceeding 400F!

Lighting Optimization

  • Up to 94% light transmission with UV
  • Diffused light allows for reduction of shadows and improved plant growth

Pictured to the left one can see shadows over on the left side of the greenhouse, as this client decided to use clear ETFE on the south facing windows. As one looks over towards the right the shading disappears, as diffuse ETFE was chosen for the rooftop glazing.
