Not all shade sails are waterproof as some of them are made of cloth fabric. But there are waterproof shade sails in Arizona which are ingrained with a wide number of beneficial features.
Waterproof shade sails offer protection against harmful UV rays and also keep your patio, garden and other outdoor areas dry in the rain.
Generally shade sails were made of cloth which explains why it gets drenched in the rain. Although it offers UV protection, these sails could hardly withstand the vagaries of nature. Water proof shade sails were thus developed to provide protection against the elements of nature.
