The Windbreaks do not only have a mechanical function (avoiding the damages reported above) but contribute to improving micro climate. Also the photosynthetic activity and hydria balance lead to better results because of the decreasing of the transpiration and the evaporation.
Apparently, the best protection against wind is a stumbling block able to fully avoid all wind effects. The experience shows that in order to have an efficient barrier, it must have 50% permeability. A stumbling block would cause currents to run back, and would limit the protected area. See photos below.
SYNTECH windbreak net with a protection of about 50% (optical density) it reduces the force of the wind by a 40% on extension 8/10 as wide as its height. In seaside areas very much beaten by wind and where a need is to filter the sand and to fix away the salt content of the sea area, it is possible to use a thicker weave of 70%.
SYNTECH windbreak net using thicker weave has a protection power of about 70% (optical density) and reduces the wind by 60%. Thicker weaves are not recommended because they would cause turbulence in the upper and lower windy areas. See photo 2 (B). SYNTECH windbreak net are produced in the following heights, 100m, 150cm, 200cm, 300cm, 400cm,. They have high mechanical durability values and are absolutely non-run.
SYNTECH net installed as anti dazzle barriers in the middle of the high way, decreases the dazzling effects respectively by 50% and 70% and make them bearable to the eyes. Installed in the external sides of the road prevent the cars from skidding because of the strong wind. In Sandy areas on light soils, they keep the sand away from the road. See photo below.
