Take on everything from the wet to the ablaze with WeatherMax FR Black 355, a fire-retardant awning and marine fabric. Like WeatherMax 80, it is of a durable weight. In fact, WeatherMax FR is 8.5 ounces per square yard, heavier than the 8-flat ounces found in WeatherMax 80. This aids in durability and makes the black fabric especially proficient in awning, marine, and canopy applications. In addition to its fire resistance, WeatherMax FR has a water-repellent finish to protect against heavy rain and an antimicrobial agent to prevent mildew, fungus, and bacterium.
