SUNTHERM EVA 3

Suntherm Thermal cover films Thermal Effect (IR) By incorporating an IR additive, thermal cover films absorb and reflect infra-red radiation in the range between 7-15 microns (radiation reflected from all bodies in the greenhouse). This reduces the loss of energy accumulated in the plant foliage into the atmosphere, and prevents the cooling of the foliage at night, which is essential for maintaining higher foliage temperatures – especially on cold nights. Moreover, when the foliage temperature is higher than the air temperature, the plants are drier, and this reduces incidents of foliage diseases. In addition, thermal cover films help save heating costs. The use of thermal cover films with the IR additive has been shown to increase crop yield in comparison to cover films without the IR additive. Light diffusion and Shaded The light diffusion feature improves photosynthesis efficiency by enhancing the exposure of different plant parts to visible light. This is especially important in model crops with a developed landscape such as tomatoes, cucumbers, zucchini, pepper, roses and more. Special additives are used in the cover films to promote light dispersion, and with minimal reduction to the light entering the greenhouse. In addition to improving photosynthesis efficiency, Light Diffusion cover films also help to reduce damage caused by direct sunlight to sensitive crops such as peppers and eggplants and prevent burns. Anti-Dust Effect By using our advanced 5-layer extrusion technology, we can include a dust-reducing additive to the top layer of our cover films. In this manner, the upper layer of the cover film is especially smooth, and this significantly reduces the accumulation of dust. Anti-virus Effect Additives are used to significantly reduce the damage caused and viral diseases transmitted to the plants by various insect pests. This also significantly reduces the proliferation of foliage diseases, especially botrytis, as well as the “blackening” of red rose petals. As a result, the use of fungicides and pesticides can also be significantly reduced. In addition, by absorbing the UV radiation, our cover films also reduce contact with various pests, viral diseases transmitted by those pests, and the “blackening” of the petals.
