I believe there are two popular fabrics used in RV awnings. The less expensive one is made of Vinyl. There are several different grades of awning material made of this material and they are usually at least two ply thick and are waterproof. Some have a tendency to delaminate after several years of service.
The second type is made of an acrylic material. This material is more expensive, is a woven material and seems softer and quieter to the touch. It is most often found on more expensive motorhomes. I don't know how waterproof it is but it seems to work very well and lasts a long time. Awnings made of this material are usually all one color and not shaded like many of the vinyl ones are.
That is about all I know about awnings. I have an acrylic one on my home and a vinyl one on my trailer. Both have been in service for quite a few years but the one on my trailer is about ready to be replaced (11 years old)due to cracking and delamination in a couple of places. The one at home is still in excellent shape but the color has faded just a bit over the years.
Hope this helps.
