WeatherMax 80 fabric uses solution-dyed yarns that are fade-resistant and stand up to the abuse of UV radiation, snow and cold—two reasons that it was chosen by Stoett Industries to fabricate three-season rooms. Because Stoett’s vertical panels are pulled up and down frequently, the fabric must also be lightweight and durable. WeatherMax is stronger and more abrasion-resistant than acrylic, according to the manufacturer, and is completely recyclable. The HydroMax finish repels water and is breathable, to limit the growth of mold and mildew. Twenty colors are available.
