PE tarpaulins are usually made of polyethylene (Polyethylene). They are mainly used for sunshade, rain protection and sun protection, rather than materials specifically designed for windproofing. Although PE tarpaulin can block wind to a certain extent, it is not a material specifically designed to withstand strong winds or extreme weather conditions.

If you need a windproof covering, it's best to choose a material specifically designed to be windproof, such as a canvas or polyester tarp. These materials are generally sturdier and better able to withstand wind forces, especially in adverse weather conditions.

In short, PE tarpaulin can provide a certain degree of wind protection, but it is not the best choice. If you need stronger windproof performance, it is recommended to choose other materials.
