As the shade sails market growing, more and more requirements for having shade sails and structures to be waterproof comes up, some branded shade cloth producers dedicated themselves to studying and pushing forward shade fabric technology, and they eventually produced a waterproof shade cloth, it is a kind of shade cloth with a special waterproof polymer coated at one side which makes shade cloth waterproof. 

Compared with some cheap polyester waterproof fabric, which has a very short product life and actually not the right choice for outdoor shade sails, waterproof shade cloth absolutely carries much longer product life time since its un-coated side carry 10 year UV warranty and the coated side carry at least 5 year UV warranty. 

This fabric has been accepted and used by most shade sails and structure manufacturers around globe. We Sunshade Union is one among them.
