The resistance of a terrace awning to rain is not always the same. So it depends primarily on what fabric the sheathing was made of. Most often we deal with polyester. What is worth emphasizing, in one of the last phases of its preparation for further use, the material is secured with acrylic varnish. It is this action that ensures a higher than normal resistance of the terrace awning to rain.
Of course, we can take additional steps ourselves to strengthen it. For this purpose, it is worth ensuring that the angle of inclination of the awning is at least 14 degrees. In this case, the cover will not only cope with light rain or drizzle, but also will not pose a threat to people sheltering under it. A certain problem may be primarily those rainfalls that last longer or are stronger. If we do not want to expose the awning to damage, then rolling it up will be the best solution.
