Light Transmission (PAR Range)
The total light transmission of the Greenhouse covering film is extremely important for Photosynthetically Active Radiation, 400 to 700 nanometers is necessary. The intensity of these wavelengths (PAR Range), directly influences the growth and development of green plants.

Widths:

• 24′
• 32′
• 40′
• 48′

Length: Our master rolls ensure we carry enough poly, at any given time, to meet even the most ambitious re-poly projects.

Light Diffusion
The light diffusion increases photosynthetic efficiency by providing more homogeneous light from all directions. The film reduces shadows, helps minimize burning and ensures better distribution of light.

Thermal Effect
During all day, all wavelengths add heat to the Greenhouse. In the evening it cools down and re-emits radiation within the IR range. Special properties are incorporated within the film which blocks IR radiation and helps maintain a controlled temperature in the Greenhouse, providing plant insulation and reducing frost damage.

Anti-condensation properties modify the film surface; as a result, water droplets are separated into a continuous water layer which subsequently runs down along the slope of the film. These films increase light transmission and reduce water drip.
