Wind barrier walls serve much the same function as wind-breaking walls but may be more sturdy in structure. They are intended to shield particular areas from strong winds and can be of use in urban situations where wind speed around buildings is reduced, agricultural fields to protect crops, and alongside highways so traffic survival increases. The walls are useful for controlling wind flow in an area, hence making it more comfortable and safe. They are generally made of hard materials that are durable and can withstand rough weather conditions. Besides being functional, they are designed to look good.
