Regular awnings are usually designed to protect against the sun; there are no waterproof awning fabrics. Acrylic awning fabrics offering sun protection are impregnated to make them water-repellent, enabling them to withstand light, brief rainfall when inclined at an angle of at least 14°. In the event of heavy or prolonged rainfall, you should always retract awnings to prevent damage. If an awning has been retracted while wet, you should always extend it again as soon as possible to allow it to dry.
