Basically, vinyl is made up of PVC with a characteristic top coat that offers maximum resistance to slip. It is also stretchable and therefore does not crack and cause leakage in the patio cover. In addition, vinyl covers are easy to maintain except for cleaning of regular dirt and grime. Vinyl patio covers are treated with chemicals to resist UV rays and fungus so they do not lose their pattern or color. They can be installed in any weather because the diverse weather conditions do not influence or cause hindrance to its installation.
