New Versions 1. Pneumatic wind dam. Here, the tree plantings are replaced by the pneumatic structures. A wind dam of such kind is rather cheap, it may be built quite easy and quickly, it is easy to modify and simple in control, but its service life is shorter.

2. Panel wind dam. Here, the wind conducting partitions are made as a system of panels fabricated from rigid material, sheets of strong fabric or film. Its drawbacks and advantages are the same as of pneumatic wind dam.

Both wind dam versions may be used together with the planted type wind dam. See: brief description of patent applications.
