Wind loads vary based on location and the placement and installation of the vertical posts and horizontal rails. When the fencing is installed according to specifications, wind is never a problem. As for weathering, vinyl does not rust, and it holds up better than any alternative fencing material on the market. All components are designed to allow for normal expansion and contraction with varying temperature, and the fencing will withstand even the most extreme weather conditions. It will not deform in the hottest weather, nor will it crack or break on the coldest night. CAUTION: If you live in the Southwest, where the sun tends to be stronger than in other parts of the country, weathering due to ultraviolet radiation can be a problem—UNLESS it’s DuraMax fencing. DuraMax fencing is the only vinyl fencing manufactured in the Southwest. Its vinyl is extruded from a specially formulated DuraResin 3 material that contains 12 parts per hundred titanium dioxide, which acts as an effective sunscreen. DuraResin 3 also contains special UV inhibitors and modifiers designed to withstand strong UV sun rays. Unlike DuraMax, other brands of fencing are manufactured in regions where the sun is less intense, and they are extruded from resins that are NOT formulated to withstand intense UV.
