Understanding ETFE Material
Ethylene Tetrafluoroethylene (ETFE) is a fluoropolymer that has been extensively used in Japan for decades, though it remains relatively new in the United States. This unique material is gaining traction as a glazing solution for greenhouses, thanks to its exceptional properties. At Ceres, we are thrilled to provide this innovative glazing material for clients looking to retrofit their existing greenhouses or invest in a complete Ceres energy-efficient ETFE cannabis greenhouse. Let’s review the benefits of using ETFE for your greenhouse project.
Benefits of ETFE Greenhouse Film
ETFE stands out for its superior light transmission capabilities, allowing over 95% of light, including the full UV spectrum, to enter your greenhouse. This selective transmission is crucial as it not only allows UV light but also optimizes Photosynthetically Active Radiation (PAR), essential for cannabis growth. Even in low natural light conditions, ETFE ensures that plants receive the necessary wavelengths for growth.
UV light, particularly UV-A, is vital for cannabis health, promoting faster and healthier growth and enhance both yield and terpene profile of cannabis. Additionally, UV light helps control pests and reduces mold, fungus, and plant diseases, leading to healthier plants.
ETFE’s excellent light transmission also enhances energy efficiency by significantly reducing the need for supplemental lighting, resulting in substantial energy savings and a lower carbon footprint. When installed in multiple layers, ETFE’s thermal properties effectively retain heat during colder months and minimize heat gain during warmer months, lowering heating and cooling costs.
Beyond energy savings, ETFE can boost cannabis crop yields and revenue for greenhouse owners. By optimizing light transmission and creating an ideal growing environment, ETFE helps growers produce higher-quality crops in larger quantities, translating to higher market value and increased profitability.
ETFE is lightweight yet incredibly strong. It weighs only 1/100th of glass, allowing for wider truss spacing and less shading in your greenhouse. This feature also leads to cost savings in greenhouse design and construction. Despite its light weight, ETFE is remarkably durable, capable of elongating up to 400% without breaking, making it suitable for areas prone to hail, high winds, or earthquakes. We offer various thicknesses of ETFE (60 μm to 300 μm) to address specific weather challenges.
ETFE also boasts longevity and minimal maintenance compared to traditional materials like polycarbonate. While polyethylene greenhouses need re-sheeting every 3-5 years due to decreased light transmission, ETFE retains its capacity well, losing only about 5% over 20 years. Some ETFE greenhouses in Japan are still effective after 30 years, thanks to ETFE’s resistance to UV radiation and chemical damage, maintaining clarity and structural integrity for decades.
Moreover, ETFE is self-cleaning due to its nonstick surface, allowing snow and debris to slide off easily, maintaining light transmission levels. Its resistance to issues like drip marks further reduces cleaning and maintenance needs, lowering operational costs over the greenhouse’s lifespan. Choosing ETFE means enjoying enhanced growing conditions and significant time and resource savings, boosting overall efficiency and productivity.
Clear ETFE vs. Diffuse ETFE
ETFE can be installed in one, two, or three-layer configurations. The outer layer, thick (100-300 microns), protects the greenhouse from elements and is clear to allow up to 95% light transmission. The thinner inner layer (60 microns) creates a diffuse effect, eliminating shadows and scattering light, allowing it to penetrate the plant canopy more effectively. An air bubble between the layers gives it an R-value of about 1.8 ft²·°F·h/BTU (US) or 0.32 m²·K/W (SI). ETFE film is available in clear or diffuse options.

Flexible and Versatile ETFE
ETFE is highly flexible and can be shaped into complex forms, offering greater design flexibility in greenhouse construction for efficient space use and improved aesthetics. Besides greenhouses, ETFE is used in various structures like sports stadiums, hospitals, and shopping centers due to its aesthetic appeal.
