A windbreak wall is a structure designed to decrease the speed at which wind travels. It also protects areas from wind-related harm. These walls are especially effective in agricultural settings where they help buffer plants against strong winds, as well as improving pedestrian comfort in city planning and reducing the effect on buildings near yours of windblown dust and chill air. Wind-break walls can be made from any number of materials including earth, wood, or concrete and their effectiveness depends on their height, how dense they are, and what design is used. They lower wind speed, making the environment more comfortable. They help to cut down noise levels and privacy.
