A thin ETFE film, F-CLEAN® Greenhouse Film is the preferred covering material for horticultural greenhouses as it lets in more light than glass, PE film, polycarbonate and PMMA sheets. By allowing maximum UV light transmission (up to 94%), F-CLEAN ensures earlier harvest of better quality fruit and vegetables and more colorful flowers. Low surface energy gives F-CLEAN film non-stick and self-cleaning properties so greenhouses remain clean naturally with rain or snow. And snow will automatically slide off, saving the cost of labor-intensive and expensive snow removal. No condensation will ever fall onto plants as F CLEAN has excellent anti-dripping properties. Highly durable, this ETFE film has proved to protect greenhouses for more than 25 years without showing signs of deterioration. Grades range in thickness from 60 µm (2.4 mil) to 100 µm (4 mil).
