There are many variations of vinyl fabric on the market, but the basic vinyl is a polyester fabric that is laminated on both sides with vinyl. The resulting product is a strong, waterproof fabric that has very good UV and mildew resistance as well as exceptional dimensional stability, tensile and tear resistance. Vinyl has fewer choices of color and patterns than canvas and does not have the breathability benefit that canvas offers, but it is more easily maintained, does not stretch and is water proof. There are varying grades of vinyl fabric, the difference being variations in the polyester base fabric as well as differences in the types and applications of the vinyl laminate. Vinyl is used for awnings, canopies, cabanas, carports, entry awnings, patios and outdoor rooms. Commercially it is a popular choice for outdoor dining areas and outdoor bars. Most vinyl fabrics are fire retardant and will accept graphics.
