This is an embossed, vinyl-laminated polyester fabric specifically designed for RV pop-up enclosures. Mildew-resistant, waterproof and long-lasting, this innovative fabric combines vinyl and polyester in a construction that results in the highest tear and tensile strength available. This vinyl-laminated fabric is flexible, highly UV resistant and flame retardant. There is a right and wrong side to this outdoor fabric, meaning that only the vinyl-laminated side should be exposed to the outside.
