Why is wind break good?

Answer 1

I am not sure in which context you are asking this question, but in general, wind break will stop wind from entering an area, thus eliminating wind chill or drafts.

In an uninsulated or partially insulated house, putting up a barrier of trees can stop the wind from hitting the house. If the wind can not get through cracks in the walls, there will be less of a draft, and cold air will not be able to enter forcibly.

With a windbreaker jacket, the same concept applies. The fabric of the jacket is woven in a manner that wind cannot enter the jacket, bringing in cold air with it and carrying the warm air surrounding your body away.

In short, wind break allows for climate control by stopping or slowing the redistribution of cold air.

Answer 2

Wind breaks are beneficial because they can reduce wind erosion, protect crops and livestock from strong winds, create a microclimate that can improve crop growth, and provide habitat for wildlife. By reducing wind speed and force, wind breaks can also help conserve soil and reduce energy costs for agricultural operations.
