Resistance to Climatic Conditions
Sun Selector films successfully withstand climatic conditions throughout the world. These include extreme temperatures ranging from -22EF to -122EF. They are also resistant to severe weather and air pollution.
The excellent optical features of Sun Selector films allow optional light transmission. Maximum light transmission in the visible range (PAR) between 0.4 to 0.7 micron is the required range for photosynthesis and various morphogenetic processes.
Sun Selector's triple-layer construction results in a smooth film that prevents dust accumulation on the outside. This is an important feature to insure maximum light transmission.
Polyethylene films are ideal for greenhouses, tunnel passages, and low tunnels. Their light weight and flexibility enables fast, easy installation. Transporting the films is convenient and their use enables savings in construction expenses.
IR additives enable films to absorb or reflect infrared radiation in the range of 7 to 15 microns. This is the radiation reflected from the earth to space. Absorption or reflection in this range reduces loss of energy that has been accumulated throughout the day in the greenhouse and prevents heat loss at night. This is an important advantage for farmers especially on cold nights and results in substantial savings in heating expenses. Sun Selector films has resulted in a 30% increase in yields as compared with films lack IR additives.
A.F. (Anti-Fog) Action
Anti Fog improves light transmission and prevents water from accumulating on the film and dripping on the plants. Incidence of disease is thus reduced. Cool drops on the plant foliage lower the temperature of the plant at night and may cause scorching during the day.
